Do Intact Viral Particles Survive Excimer Laser Ablation? 准分子激光削融后有完整的病毒颗粒存活吗?
The spectra confirm the formation of the intermolecular excimer of polyelectrolyte SMP, in which the chro-mogenic groups are on the main chains. 证实了生色团在主链上的聚电解质SMP分子间激基缔合物的形成.

An excimer laser was first used to clear coronary arteries in 1987 at the University of Ottawa Heart Institute, but that involved open heart surgery.
"With the proper funding, we believe Lasertechnics could introduce a one kilowatt, commercially reliable excimer laser within 18 months," he added.
The excimer laser delivers pulses of light only a few billionths of a second long, so once a doctor determines the desired shape of the cornea, the sculpting process would take only about 30 seconds.
