Abstract:
A multibeam laser manipulation technique has been applied to noncontact and nondestructive optical fusion of two dye-containing microdroplets or that of a dye/water droplet and a porous silica gel particle in solution. Characteristics of the dye/particle(s) before and after coalescence have been followed simultaneously by microspectroscopy. Application of the multibeam laser manipulation-spectroscopy method in microanalytical chemistry is discussed.
