A novel multifunctional nanoreactor was designed for highly efficient detection and profiling of membrane proteins using macroporous siliceous foams (MSF) with large pore size of ∼ 70 nm and hydrophobic surface (contact angle over 100°). By introducing organo groups (e. g. from bis(triethoxysilyl)ethane) on the surface of MSF, the modified material was employed for selective extraction and in situ...
A laser desorption/ionization mass spectrometry method has been constructed based on metal oxide particles for analysis of small nutrients in milk sample. Owing to the desirable structural parameters and efficient laser desorption/ionization performance, our method offers high sensitivity ∼pmol, low sample consumption down to 10 nL, and facile sample preparation for practical use. This work makes...
