Patent ID: 10786465

Abstract:
A composition comprising a nanoparticle, wherein the nanoparticle comprises a polymer/copolymer conjugated to a moiety is disclosed. A method of forming a nanostructure includes stirring poly(lactide-co-glycolide (PLGA) and 11-Ethyl-3-(dimethylaminopropyl) carbodiimide (EDC) in CH2Cl2 to create a PLGA mixture, n-boc-ethyelenediamine and N,N-Diisopropylethylamine (DIEA) are added to the PLGA mixture to create a reaction mixture. The reaction mixture is then precipitated in cold diethyl ether to form a purified polymer, which is then dried. The dried and purified polymer is then reconstituted in CH2Cl2:TFA solution and stirred under inert conditions. The product of the reconstituting step is evaporated to form a clear viscous residue that is dissolved in CH2Cl2 and then precipitated in cold ether to form a polymer. These functional polymers can encapsulate a variety of bioactives forming nanosystems improving the performance of bioactives.
