Fig. 7From: Optical and electron microscopy study of laser-based intracellular molecule delivery using peptide-conjugated photodispersible gold nanoparticle agglomeratesMetabolic activity of cells. Long-term influence on laser viability tested 48 and 72 h after laser treatment using PrestoBlue. All values are background corrected for the blank with only cell culture medium. Laser irradiation has no influence on cell proliferation. Cells killed with methanol/ethanol act as negative control. n = 6Back to article page
