Tiny magnets to repel drug counterfeiters

Abstract:
A large pharmaceutical packaging company is hoping that nanotech security tags devised by a small Singaporean firm will help it combat counterfeit drugs. India-based drug supplier Bilcare says it is in talks with Indian pharmaceutical companies to commercialise the nanoscale magnetic fingerprinting technology by Singular ID, a spin-out they bought for SGD 19.58 million (£7 million) earlier this month.

Singular ID's security tags are ceramic thin films dotted with irregular pores that are filled by 200nm wide magnets. Each film holds a randomly generated magnetic pattern that can be stored in a database: in essence, a unique fingerprint that is easy to manufacture but virtually impossible to copy.

According to Bilcare, Pfizer and other US-based pharmaceutical companies have also shown 'keen interest' in the system.
