A　random　laser　carrying　the　scattering　information　on　a　biological　host　is　a　promising　tool　for　the　characterization　of　biophysical　properties.　In　this　work,　random　lasing　from　label-free　living　cells　is　proposed　to　achieve　rapid　cytometry　of　apoptosis.　Random　lasing　is　achieved　by　adding　biocompatible　gain　medium　to　a　confocal　dish　containing　cells　under　optically　pumped　conditions.　The　random　lasing　characteristics　are　distinct　at　different　stages　of　cell　apoptosis　after　drug　treatment.　By　analyzing　the　power　Fourier　transform　results　of　the　random　lasing　spectra,　the　percentage　of　apoptotic　cells　could　be　distinguished　within　two　seconds,　which　is　more　than　an　order　of　magnitude　faster　than　traditional　flow　cytometry.　These　results　provide　a　label-free　approach　for　rapid　cytometry　of　apoptosis,　which　is　advantageous　for　further　research　of　random　lasers　in　the　biological　field.
