Biosensors have become an important tool in health, safety, and scientific fields. The market for biosensors is highly competitive, but highly sensitive tests cost large amounts of time, money and training. The development of small and cheap devices would shake the market and create an accessible supply of technology to people in need. This is the potential microresonators have. They are extremely cheap to produce because they are made of miniscule amounts of glass. They can achieve results almost instantaneously, and would require no special training to operate. The devices could be the size of smartphones using disposable sensor chips to perform different sensings. Other less sensitive techniques have achieved devices of smartphone size, but microresonators can operate in real time while giving more sensitive results than any previous sensor for lower costs.
