Stratum corneum permeabilization with photoacoustic waves generated by piezophotonic materials
Abstract Photoacoustic (PA) waves generated by short laser pulses absorbed by piezophotonic materials are shown to permeabilize the stratum corneum to large molecules and proteins. Two minutes of such PA waves at a laser pulse frequency of 20Hz...

Large precursor tolerance database search — A simple approach for estimation of the amount of spectra with precursor mass shifts in proteomic data
Abstract Mass measurement and precursor mass assignment are independent processes in proteomic data acquisition. Due to misassignments to C-13 peak, or for other reasons, extensive precursor mass shifts (i.e., deviations of the measured from...
