Direct observation of laser generated free radicals from a myocardium target site.
The first direct observation of unstable free radicals generated by laser irradiation of myocardium samples has been performed by EPR at 100 K. Characteristic iron signals are measured for pulsed laser ablation of the sample. The EPR results are discussed in relation to the relative efficiency of the various types of lasers to produce free radicals. A comparison is made of the types of free radicals produced by the action of pulsed vs continuous wave (cw) laser energy.
