Figure 3From: Inactivation of viruses by coherent excitations with a low power visible femtosecond laserThe three typical assays for a sample with nominally prepared 5 × 102 pfu of M13 bacteriophages (a) without laser irradiation; (b) after laser irradiation for about 10 hours. The extremely few number of plaques observed in the irradiated sample is indicative of almost complete inactivation of the M13 bacteriophages in the sample.Back to article page
