As a kind of environmentally sensitive and controlled drug release systems
hydrogel nanoparticles have shown more and more potential application in the field of biomedicine. They were mainly used in the delivery of biomacromolecules such as polypeptide
protein etc.
which have the properties as strong toxicity and side effect
short biological half-life time
easily degraded by bioenzyme. This review mainly summarizes the classification
preparation of hydrogel nanoparticles and their application in the field of biomedicine.
