Claim 17:
18. The method according to claim 13, wherein one of the following applies:
(a) the nanoparticles are obtained as vesicles when the molar ratio of monomeric material to macroinitiator compound in the solvent is from 100:1 to 500:1, and the reaction is allowed to occur for a period of time such that an average ratio of monomeric material repeating units to macroinitiator repeating units from 1:9 to at least 9:1 is obtained;
(b) the nanoparticles are obtained as micelles when the molar ratio of monomeric material to macroinitiator compound in the solvent is from 40:1 to 100:1 and the reaction is allowed to occur for a period of time such that an average ratio of monomeric material repeating units to macroinitiator repeating units from 1:100 to 10:1 is obtained; or
(c) the nanoparticles are obtained as cylindrical worm structures when the molar ratio of monomeric material to macroinitiator compound in the solvent is from 40:1 to 200:1 and the reaction is allowed to occur for a period of time such that an average ratio of monomeric material repeating units to macroinitiator repeating units from 1:1 to 100:1 is obtained.
