How about a molecular nose using nanoparticle based sensors for sniffing and identification of proteins? University of Massachusetts Amherst scientists have gone ahead and developed this nose which can be used for detection of various proteins which can be used for diagnosis of diseases such as cancer. The nose operates in a holistic manner and in this case gold nanoparticles were used which can be easily manipulated. A florescent dye was also added to the sensors in order to figure out which dye was interacting with which protein.
Six types of nanoparticles were used for sensing seven types of proteins and a technique was also developed for dealing with different protein concentrations and by using the raw data along with the statistical analysis the proteins were detected with an accuracy of around ninety six percent. It is more reliable and economical as compared to the current technologies being implemented.
