Photothermally induced release from liposome suspended in mixture solution of gold nanoparticle and thermo-sensitive polymer

- Gold nanoparticles (GNP)/PNIPAM-BMA mixture are mixed with DPPC liposome.
- The temperature of suspension increases due to the treatment of near infrared (NIR) irradiation to GNP.
- A stepwise release takes place under NIR irradiation for the thermal contraction of the thermo-sensitive copolymer and the phase transition of the liposome membrane.
