Embodiment 1
[0019] Example 1 The glutathione-functionalized hybrid material is used for the separation and enrichment of glycopeptides.
[0020] Preparation of glutathione-functionalized hybrid materials:
[0021] 1) Preparation of vinyl-functionalized hybrid materials: First, weigh 5 mg of dodecylamine and 20 mg of CTAB into a centrifuge tube, add 175 μL of ethanol and 125 μL of water, ultrasonically dissolve to form a homogeneous solution, and then add 100 mg of Tetraethoxysilane and 100mg 7-octenyltrimethoxysilane were placed in a water bath at 40°C for 24 hours; the hybrid material was washed three times with ethanol / water solution (1 / 1, v / v) , Vacuum drying at 60°C for 12h to obtain a vinyl-functionalized hybrid material.
[0022] 2) Preparation of glutathione-modified hybrid material: First, 20 mg of glutathione and 2 mg of photoinitiator DMPA were dissolved in 10 mL of an aqueous solution with 50% ethanol content. Next, spread 100 mg of the vinyl-functionalized hybrid material on...

Embodiment example 1
[0030] Implementation case 1 prepares the infrared image of the hybrid material such as figure 2 As shown, in the infrared spectra of the functional monomers tetraethoxysilane and 7-octenyltrimethoxysilane, the wave numbers are 2974 and 2889cm -1The absorption peak at Si-O-C 2 h 5 The C-H stretching vibration in . And the wave numbers are 1391, 1296cm -1 The absorption peak at -CH 3 The symmetric bending vibration of C-H in the middle. 1100 and 1073cm -1 The absorption peak at Si-O-C 2 h 5 Si-O stretching vibration in . After the free radical reaction is completed, a 1602cm -1 The C=C stretching vibration peak at 1391, 1296cm -1 attributable to -CH 3 The symmetrical bending vibration of C-H in , while 1100 and 1073cm -1 attributable to Si-O-C 2 h 5 The Si-O stretching vibration doublet in the -1 Si-O broad peak substitution of Si-O-Si. This shows that the C=C functional group has been introduced into the synthesized hybrid material, which provides favorable co...
