Figure 2From: Inactivation of viruses by coherent excitations with a low power visible femtosecond laserThe three typical assays for a sample with nominally prepared 1 × 103 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 a manifestation of almost complete inactivation of the M13 bacteriophages in the sample.Back to article page
