Nitrogen-doped porous carbon material derived from metal–organic gel for small biomolecular sensing

A simple preparation method of N-doped PCM via direct carbonization of nitrogen containing metal–organic gel was demonstrated. The resultant N-PCM, with high surface area, mesoporosity, and high UV absorption ability, was used as a matrix to assist small-biomolecule sensing in laser desorption/ionization mass spectrometry.
