87036, Italy 10.3762/bjnano.9.37 Abstract In the last decade, much interest has grown around the possibility to use liquid-crystal droplets as optical microcavities and lasers. In particular, 3D laser emission from dye-dopedcholestericliquidcrystals confined inside microdroplets paves the way for
the field of sensors and for the development of anti-counterfeiting labels.
