As per a research at Purdue University it has been found out that Nanocantilevers could play a vital part in designing a new class of ultra small sensors which could help in quick detection of bacteria, pathogens and viruses. They could be useful as they vibrate at different frequencies when contaminant stick to them and this could indicate the presence of dangerous substance. Since nanocantilever’s are of minute size and more sensitive than larger devices therefore it can aid in the development of advanced sensors which can detect minute quantities of contaminant and hence provide a warning regarding the presence of dangerous pathogens. Cantilevers vibrate faster after antibodies are attached and the vibration would be faster if the protein coated nanocantilever is longer. This would certainly help in designing future nanomechanical sensors which use cantilevers.
