BINA scientists are developing a technique for measuring the local spectrum at each point of a sample. The spectrum contains much more information than just a color image, and can be used for diagnostics and other biomedical applications. The team aims for fast measurements of a large sample under a microscope, so that a pathological sample can be diagnosed in a rather rapid manner. These measurements are based on Fourier spectroscopy, which relies on collecting the light from the sample through a unique optical system.

Monitoring the dynamics of droplet evaporation has diverse potential applications, such as characterizing the surface and combustion efficiency of fuels. A BINA team has developed a technique for the monitoring of the evaporation of sub nano-liter volume droplets. The method is based on the dynamically-varying interaction between the fluid, the surface to which it is applied and its surroundings. In this method, the interference fringes of reflections from a pendent droplet at the tip of a standard fiber are recorded and analyzed. The temporal profiles obtained in the experiments provide distinct signatures of the specific fluids.
