Nanomagnets Provide Protection from Lethal Counterfeit Drugs

Because of the random patterns that the nanomagnetic particles form, even the makers of the tags can't copy them

Nanomagnets Provide Protection from Lethal Counterfeit Drugs

A company that started off with the name SingularID over half a decade ago has long impressed me with its ability to take a nanomaterial—in this case nanomagnets—and develop a suite of tools around its physical phenomena to sell a product that helps in brand protection.

Bilcare Research acquired the small start-up back in 2007, and it seems the anti-counterfeiting technology could have a real impact in combating drug counterfeits in India, according to this recent BBC story

According to the BBC piece, counterfeit drugs are a $200 billion business whose main target continues to be poor and developing countries. What we’re talking about here is not just lost profits for the genuine drug producers, but also sometimes lethal consequences for people who need a particular drug but receive a fake one that lacks the active ingredient needed—or simply poisonous drugs.

The article goes on to explain that a number of technologies, including Bilcare’s, are under consideration for combating the counterfeit drugs. What I always found intriguing about the nanomagnet solution developed by SingularID and now marketed by Bilcare is that even they can’t make a copy of it—the nanoparticles position themselves in random patterns.

But beyond that, what always attracted me to the story of this technology is that the developers didn’t just settle with a nanomaterial and a patent and expect the world to come knocking on their door with lucrative licensing agreements. Instead, they developed an entire product that they could sell to someone. This has been surprisingly rare in the brief time that there have been nanotech companies.

3 Ways 3D Chip Tech Is Upending Computing

AMD, Graphcore, and Intel show why the industry’s leading edge is going vertical

A crop of high-performance processors is showing that the new direction for continuing Moore’s Law is all about up. Each generation of processor needs to perform better than the last, and, at its most basic, that means integrating more logic onto the silicon. But there are two problems: One is that our ability to shrink transistors and the logic and memory blocks they make up is slowing down. The other is that chips have reached their size limits. Photolithography tools can pattern only an area of about 850 square millimeters, which is about the size of a top-of-the-line Nvidia GPU.

For a few years now, developers of systems-on-chips have begun to break up their ever-larger designs into smaller chiplets and link them together inside the same package to effectively increase the silicon area, among other advantages. In CPUs, these links have mostly been so-called 2.5D, where the chiplets are set beside each other and connected using short, dense interconnects. Momentum for this type of integration will likely only grow now that most of the major manufacturers have agreed on a 2.5D chiplet-to-chiplet communications standard.
