Abstract:Desorption/ionization
induced by neutral clusters (DINeC)
was employed
for the soft transfer of organic and biomolecules, such as porphyrins
and peptides, from a bulk sample onto any substrate of choice. Qualitative
analysis of the deposition technique was performed by means of mass
spectrometry, demonstrating that the deposited molecules remained
intact due to the soft nature of the transfer process. Deposition
rates were studied quantitatively using a quartz crystal microbalance;
layers of intact biomolecule… Show more
