Abstract
Hamrick and Cleary recently reported alterations in biological systems produced by the intense acoustic transients that are generated when a Q-spoiled laser impulse is used to irradiate an optically absorbing material1. The statement that their samples of tobacco mosaic virus (TMV) were exposed to “positive acoustic pressure transients”, coupled with the conclusion that the breakage of particles was found to depend on the surface boundary conditions of the irradiated medium, may, however, lead to some confusion.
