A brain-computer interface that could one day connect humans and computers without opening the skull sounds like something ripped straight from a sci-fi movie. Now, AI pioneer and futurist Ray Kurzweil has joined neurotechnology startup Subsense as a product and vision advisor, backing an experimental approach involving engineered nanoparticles delivered through the nose.

But before the internet runs with the idea of a “brain chip in a nasal spray,” there is a major reality check: Subsense’s NanoBCI is still in preclinical research. Human clinical testing remains a future goal, and the technology is not approved for marketing in the U.S.

Ray Kurzweil Joins Subsense to Develop a Non-Surgical Brain-Computer Interface

Subsense announced Kurzweil’s appointment at its AI Meets the Brain annual forum in Palo Alto, California.

The move brings one of the most recognisable names in AI futurism into a company attempting something radically different in the brain-computer interface space: creating neural access without surgically implanting electrodes or a computer chip inside the skull.

Kurzweil has spent decades exploring the convergence of artificial intelligence, nanotechnology and neuroscience, making his involvement particularly relevant to Subsense’s long-term ambitions.

“For years, I have believed that the convergence of AI, nanotechnology and neuroscience could fundamentally change how humans interact with technology,” said Kurzweil.

He added:

“Subsense is pursuing an approach that brings those fields together in a particularly compelling way, with the potential to move brain-computer interfaces beyond today’s surgical constraints and, over time, toward much broader applications.”

And Kurzweil isn’t exactly hiding how ambitious that future could become.

Speaking at the event, he said:

“Ultimately, we want to merge [the smartphone] with the brain,” Kurzweil said at the event.

He also argued:

“The whole point of humans is to go to greater frontiers, expand who we are.”

For Subsense, that vision fits neatly with a technology designed to bring computing closer to neural activity.

How Does Subsense NanoBCI Work Without Brain Surgery?

This is where the concept gets seriously futuristic.

Traditional implanted brain-computer interfaces generally require a device and electrodes to be surgically positioned inside the skull. Subsense is attempting to remove that surgical step by combining functional nanoparticles with an external wireless wearable device.

The company calls the system NanoBCI.

Rather than placing electrodes directly into the brain, Subsense says its approach uses two classes of functional nanoparticles that can act as an interface between neural activity and external computation.

The first involves plasmonic nanoparticles.

According to Subsense, these particles can be used for optical neural readout. They interact with near-infrared light and respond to local electrical activity, potentially allowing neural signals to be detected.

Then there are magnetoelectric nanoparticles.

Subsense says these particles can convert externally applied magnetic fields into localized electrical effects inside the brain. That could potentially provide a mechanism for targeted neuromodulation — essentially giving the system a way not only to read neural activity but also to influence specific neural circuits.

That creates an important distinction.

The company’s ultimate concept isn’t simply about reading the brain. It is about building a bidirectional brain-computer interface capable of both interpreting neural activity and influencing neural activity.

The Nasal Route Is the Most Unusual Part of Subsense’s Brain Interface

Subsense describes its approach as “non-surgical brain access.”

The company is attempting to use intranasal administration to introduce nanoparticles and targeted localization to position them near relevant brain regions. An external wearable device would then provide wireless control of the particles.

The nasal route is significant because it is intended to avoid the conventional surgical route used by implanted BCIs.

Reporting on the technology has described the nanoparticles as travelling through the nasal passage toward the brain, including through pathways associated with the olfactory system.

That sounds wild — but it is important not to turn an experimental research concept into something it isn’t.

Consumers cannot currently use a nasal spray to connect their brains to computers.

Subsense’s system remains under development, and it has not reached human clinical use.

Subsense NanoBCI Timeline: From Animal Research to Potential Consumer BCI

The company’s development roadmap also reveals just how far away this technology may still be from everyday use.

Subsense says it has already achieved early laboratory results involving nanoparticle development, neural reading and stimulation. Its technology information describes in-vitro experiments involving neural activity and preliminary neurostimulation work, as well as early in-vivo animal research.

Its stated 2026 research includes work on nanoparticle entry into the brain and in-vivo stimulation.

Here is the company’s projected development path:

Timeline	Development Stage
2026	Research involving nanoparticle entry into the brain and in-vivo stimulation
Q4 2026	Stated target for a first in-vivo brain stimulation milestone
2027–29	Planned clinical pilots
2029–31	Projected potential clinical product
2031 and beyond	Projected consumer brain-computer interface

These are company targets, not guaranteed milestones.

Before such a system could become a functioning human BCI, researchers would need to establish that nanoparticles can be delivered safely, remain appropriately localized, interact with neural tissue reliably and perform consistently in living humans.

The current evidence described by Subsense does not establish that its technology can safely or reliably provide a functional brain-computer interface in humans.

That distinction is crucial.

Subsense Has Raised $27 Million to Develop Its Brain Interface

Despite the technology still being experimental, Subsense has attracted substantial financial backing.

In December 2025, the company announced an additional $10 million in financing, bringing its total funding to $27 million.

The additional investment came from Golden Falcon Capital and was intended to accelerate research and development involving nanoparticle sensing, biosafety, next-generation nanoparticle development and hardware miniaturization.

At the time, Subsense described its goal as creating a bidirectional BCI capable of recording and modulating brain activity without surgical implants.

The company has also established laboratory and engineering facilities in Palo Alto, California, and says it has research collaborations across North America and Europe.

Its immediate focus is medical rather than consumer technology.

Subsense says its first applications are intended to involve neurological disorders, with Parkinson’s disease and epilepsy among the conditions it is targeting.

Only after those challenges are addressed does the company’s vision expand into much broader territory.

Could NanoBCI Eventually Change Human-Computer Interaction?

If Subsense’s technology can eventually demonstrate safety, precision and scalability, the potential applications could extend well beyond treating neurological conditions.

The company says its longer-term vision could include new forms of communication and perception, neural-level human-AI interaction, cognitive enhancement and other human-technology interfaces.

This is also where Kurzweil’s involvement becomes especially interesting.

His appointment does not mean that NanoBCI has achieved a clinical breakthrough. It also does not independently validate Subsense’s scientific claims.

Instead, his role is primarily strategic and visionary, helping the company think about how its technology could evolve alongside increasingly capable AI systems and advances in neural computing.

In other words, Kurzweil isn’t announcing that the future has already arrived.

He’s helping Subsense think about what that future might look like.

Subsense vs Neuralink: What Is the Difference?

The project has naturally invited comparisons with Elon Musk’s Neuralink, another company developing brain-computer interfaces.

The biggest difference comes down to how each technology attempts to establish a connection with the brain.

Neuralink’s approach involves surgically implanting a device and electrodes into the brain.

Subsense is attempting to eliminate that surgical step through intranasally delivered nanoparticles and an external wearable system.

If Subsense’s approach eventually proves safe and effective, that distinction could be significant.

A successful non-surgical system could theoretically be easier to deploy than a technology requiring specialised brain surgery.

But there is an important catch: non-surgical does not automatically mean safer.

The nanoparticle approach introduces its own difficult scientific and medical questions.

Researchers still need to determine how precisely the particles can be controlled, where they travel, how biologically compatible they are, how reliably they can communicate with neural tissue and how they could eventually be removed or safely managed.

Those questions remain part of Subsense’s ongoing research and development.

Is Subsense NanoBCI FDA Approved? No — and That Matters

One of the biggest details to remember amid all the futuristic headlines is Subsense’s own regulatory warning.

The company states on its website that its products “are not authorized, cleared, or approved by the FDA for marketing in the US” and that its performance claims have not yet been evaluated by the FDA.

So, despite the references to AI, nanoparticles and brain-computer interfaces, this is not an approved consumer technology or available medical device.

The company’s roadmap makes that clear.

Human clinical pilots are still listed as a future stage, while a consumer BCI is projected even further away.

For now, NanoBCI belongs in the category of experimental neurotechnology, not everyday consumer electronics.

What Ray Kurzweil’s Subsense Role Could Mean for the Future of AI and the Brain

Kurzweil’s arrival gives Subsense a prominent voice associated with long-running predictions about the convergence of humans and technology.

For the company, his appointment comes as it attempts to move an unusual BCI concept from laboratory research toward eventual medical applications.

For Kurzweil, it represents another step toward a technological vision he has discussed for decades: increasingly direct interaction between humans, computers and artificial intelligence.

The immediate reality, however, is much less sci-fi.

Subsense is still conducting preclinical research. Its technology has not been approved, cleared or authorised by the U.S. FDA for marketing. Human clinical testing remains a future objective, and the company’s projected timelines are not guarantees.

If the approach ultimately works, Subsense could offer a radically different route into the brain than conventional implanted BCIs.

But for now, the idea of controlling computers through nanoparticles delivered through the nose remains exactly what it sounds like: an ambitious experimental research program — not a working consumer brain-computer interface.
