Chemists 'print' sensors for nano-objects

Young scientists from ITMO University proposed a new type of optical nano-sensors. Their operating principle is based on the interaction of light in thin films: a similar effect can be observed in soap bubbles. Such sensors can be quickly manufactured using an inkjet printer and special ink made of titanium dioxide. In the future, the sensors can be used for rapid biomedical analysis. The results are published in Nanoscale.
