The Inevitable Disconnect between Nanotechnology and Its Expectations

Vague definitions for nanotechnology account for it not meeting expectations

The Inevitable Disconnect between Nanotechnology and Its Expectations

I was reading a very professional article in the Boston Globe (I emphasize “professional” because so often these articles are not) that details the impact of nanotechnology innovation in Massachusetts when I stopped to consider why it is that people feel nanotechnology has not fulfilled their expectations.

The article starts with: “State officials and economic developers imagined new industries and jobs. Universities jockeyed for billions in research money. The news media hyped it as the next big thing. So what happened?” The answer we quickly get is “A lot, actually.”

The Globe reporter, Robert Gavin, offers some explanations for why the public has not been overwhelmed by nanotechnology’s impact that include its lack of “sexiness” and “Unlike with other technologies, there is not necessarily a consumer product at the end of the pipeline. Instead, nanotechnology often provides the components that make breakthroughs in new and existing products possible.” I couldn’t agree more. As I have said before in nanotech it’s the mundane that’s interesting.

The article goes on to share some interesting quotes from Mihail Roco, the long-time director of the National Nanotechnology Initiative (NNI), which offer up some possible timelines for nanotechnology’s development: “Nanotechnology is at about the point that IT had reached in 1975, said Roco, but has gotten there much faster. Roco estimates nanotechnology will reach IT’s 1995 stage by 2020.”

However, it neglects to address another key reason why nanotechnology has seemingly disappointed the fertile imagination of the general public. The unspoken and unanswered question seems to be: Where are the nanofactories and nanobots and the ability to make a laptop computer by pushing a button on your table-top factory?

While I have had my differences of opinion with some of the folks from the molecular manufacturing community, I do agree with them that many people believed that the nanotechnology they thought they would be getting would be more like that instead of the advanced material science and chemistry that we have today. As Philip Moriarty is quoted as saying in a recent interview “The problem with the nano- prefix is that there isn’t an area of modern condensed matter/solid state physics or chemistry that can’t be badged as nanoscience.”  

So, it seems that this is where science was in 2001 when the NNI was launched and the advanced material science of “surface reconstructions” needed funding and research and stood a far better chance of getting it if it was called “nano”. It’s worthwhile research, it will enable already existing products and even create some new ones, but maybe it’s time to say this doesn’t seem like the nanotechnology that captured our imagination because it isn’t.

Two Startups Are Bringing Fiber to the Processor

Avicena’s blue microLEDs are the dark horse in a race with Ayar Labs’ laser-based system

Diffuse blue light shines from a patterned surface through a ring. A blue cable leads away from it.

Avicena’s microLED chiplets could one day link all the CPUs in a computer cluster together.


If a CPU in Seoul sends a byte of data to a processor in Prague, the information covers most of the distance as light, zipping along with no resistance. But put both those processors on the same motherboard, and they’ll need to communicate over energy-sapping copper, which slow the communication speeds possible within computers. Two Silicon Valley startups, Avicena and Ayar Labs, are doing something about that longstanding limit. If they succeed in their attempts to finally bring optical fiber all the way to the processor, it might not just accelerate computing—it might also remake it.

Both companies are developing fiber-connected chiplets, small chips meant to share a high-bandwidth connection with CPUs and other data-hungry silicon in a shared package. They are each ramping up production in 2023, though it may be a couple of years before we see a computer on the market with either product.
