″Nanofibers for fingerprints″


″Experience shows that no two individuals have fingers exactly alike.″

Rashid-al-Din Hamadani (also known as ″Rashideddin″, 1247–1318)

In 1823, distinguished Czech physiologist, Johannes Evengelista Purkinje, published his thesis about a full nine different fingerprint patterns. And it was 1858 when Sir William James Herschel first used fingerprints on native contracts. Today, various fingerprint sensors and matching algorithms are available to capture a digital image of the fingerprint pattern and compare previously stored fingerprints.

The market for fingerprint technologies account for the largest share of the global biometrics market and is valued at USD 2.8 billion in 2010 and is expected to increase at a CAGR of 19.6% to reach nearly USD 6.6 billion by 2015 (Transparency Market Research).

In fingerprint technology, accuracy of the algorithm and print matching speed are critical elements of the system performance. Recently, by using electrospinnning technology,
a nanofiber membrane is developed that uses a commercial resin that allows ultra fast identification of latent fingerprints (DOI: 10.1002/anie.201006537). This technique is unique
in that latent fingerprints can be non-destructively lifted from surfaces and developed within
30 seconds without the need for pre-/post-treatment processes.

This emerging technology is growing at a fast rate as it is being rapidly adopted not only
in the private sector but in various government projects as well.
