The invention discloses a
drug-loading bionic
scaffold based on in-situ emulsified and homogenized
PLGA microspheres, a preparation method and application, and the preparation method comprises the following steps: step 1, adding hydroxyapatite into a collagen solution, fully mixing, adding a
photoinitiator, and fully reacting to obtain a
mixed solution A; 2, dissolving a
polylactic acid-polyglycolic acid
copolymer PLGA, adding a
drug solution needing to be loaded, and fully mixing to obtain a
mixed solution B; and 3, adding the
mixed solution B serving as an
oil phase into the water-phase mixed solution A obtained in the step 1, carrying out oscillation emulsification, and carrying out photocuring to obtain the
drug-loaded bionic
scaffold containing the homogenized
PLGA microspheres, according to the homogenized PLGA
microsphere functionalized drug-loading bionic
stent,
PLGA microspheres with
uniform size are obtained, the encapsulation efficiency of drugs is improved, and the release process of the drugs can be regulated and controlled.
