Nanotechnology and Food Remains in the Realm of Speculation and Fear Mongering

With few examples of how nanotechnology is currently being used in food, speculation rules and fear becomes the guiding principle

Nanotechnology and Food Remains in the Realm of Speculation and Fear Mongering

It still seems that the mob with pitchforks is in control of the issue of nanotechnology and food. I was reading a fairly balanced report in a publication called the Mindful Metropolis on the state of nanotechnology and food. It was thorough report with just a few hiccups, most notably the assertion that food companies spend “millions of dollars on nanotechnology research and development” and then noting that “food companies maintain a great deal of secrecy regarding nanotechnology programs.” If the latter is the case, it begs the question of how you could conclude the former.

But that is the way of this issue. Without any clear evidence of what types of nanomaterials are used in which food stuffs (we are not including nanoclays used as a filler for plastic packaging), much of the coverage of this issue is based on little more than speculation. An example of this is the various numbers provided for the amount of food products containing nanomaterials: “The Woodrow Wilson International Center for Scholars sets the number at 84; the Project on Emerging Nanotechnologies has the number at 98; and in a 2008 report on nanofood, Friends of the Earth identified 104 food and cosmetic products containing nanomaterials.”

Once again, we are told that labeling will cure this and inform consumers. But as I have argued before this proposal will do little to inform and do much to terrify people, often, if not completely, needlessly.

Then the piece really falls completely under the influence of a Friends-of-the-Earth (FoE) representative, which as an organization has demonstrated its aim to create an open debate on the uses of nanotechnology by boycotting public engagement meetings.

It all turns somewhat comical by the end when the FoE representative argues that even if nanoparticles are proven to be completely harmless in food, it would still be objectionable because people might be getting all their nutrients without eating fruits and vegetables. “What it comes down to, I’d recommend that consumers veer away from processed foods.” 

I am sure that this sentiment will really strike a chord with the affluent and comfortable who are concerned that their carbon footprint may be endangering the planet. But for the poor and starving it might be a pretty good thing to have a simple and inexpensive processed food that could supply your nutritional needs when you can neither grow nor afford the fruits and vegetables that would give you a balanced diet.

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.
