抄録

Recently, we have reported the formation of nano-particles by mixing a poor solvent into a solution of polymer, and then evaporating a good solvent. In this report, nano-particles were prepared from various biodegradable polymers. Average size of the particles was measured by dynamic light scattering spectrophotometer. The particles were observed by Field-Emission Scanning Electron Microscopy. Uniform sized particles were formed. The particle size was controlled ranging from 100 nm to 1000 nm. In the case of Poly(ε- caprolactone)(PCL), the particle size became larger with increasing the concentration of solution, and increasing the volume ratio of a good solvent / a poor solvent. Fabrication of biodegradable particles containing a drug and their concentration of drug in the particles will be reported.
