This invention provides a
cell microenvironment stabilizer that captures
hydrogen ions, its preparation method, and its application, belonging to the field of
biomedical technology. The preparation method of this
cell microenvironment stabilizer includes the following steps: (1) mineralizing CaCl2 with TGF-β1,
catalase, and
polyethylene glycol-
polyglutamic acid block
copolymer to obtain mineralized nanoparticles; (2) preparing
hydrogel microspheres under freezing conditions using a microfluidic device, and then photocrosslinking the frozen
hydrogel microspheres; (3) mixing the
hydrogel microspheres with the mineralized nanoparticles to prepare the
cell microenvironment stabilizer. This invention prepares a mineralized hydrogel
microsphere, which, as a
cell microenvironment stabilizer, can be used to block the NLRP3
cascade in chronic
inflammation, capturing
excess hydrogen ions through the mineralization layer to neutralize the acidic microenvironment. This micro / nano
bioreactor based on hydrogel microspheres can effectively interfere with NLRP3 in the microenvironment of degenerated tissues from inside and outside the cells, inhibiting chronic
inflammation.
