Synthesis and Physicochemical Properties of Polyacrylamide Nanoparticles as Photosensitizer Carriers
At present, polyacrylamide nanoparticles are attractive to drug delivery. However, some physicochemical characteristics of these nanoparticles still need to be further improved in practice. Polyacrylamide nanoparticles with an average size of 80 nm a
