The Gujarat Forensic Science University (GFSU) has come up with a cost-effective way of detecting intoxicants in the bloodstream: an innovation that is expected to make policing easier.
The varsitys Research and Development department head,Prof Y K Agrawal,had received a patent last October for successfully making a one-and-a-half inch metal sheet,which comprises Calixarene-based nano particle sensors capable of detecting 15 different kinds of intoxicants.
Prof Agrawal said intoxicants,even in the tiniest drop of blood or saliva can be traced within 15 seconds.
Depending on the percentage of narcotics present in the blood,the sensors will emit colours. Some drugs are colourless; some like barbiturates emit green colour. The sensors will immediately detect them under white light, said Prof Agrawal.
He added: It will take us a few months to come up with this product; the cost will not exceed Rs 15. The university will apply for a patent soon.
Prof Agrawal further elaborated the functioning of the product. He said: As soon as the intoxicants fall on Calixarene,the latter absorbs them and forms a complex. This result in the transfer of energy in the form of specific radiation under the spectrophotometer (an object used to detect radiation emitted by a specific complex).
Even poison can be easily detected through this instrument,which can reduce the labour of doctors in emergencies,Prof Agrawal added.
He further said: We have already used this metal chip on blood and saliva samples brought from different sources; but,forensic use is yet to be done on this chip. There are a few companies that have approached the varsity for this product. It will take a few more months before the product is launched.
