• Left hand side video shows a trapped particle
  tweezed with a femtosecond beam and an embedded
  dye undergoes two photon excitation at 400nm
• It is the average power that matters for trapping
  and the peak power which dictates the
  nonlinearity

CELLS FOR SPECIFIC DELIVERY OF DNA THROUGH THE
MEMBRANE
