1. A nanonet comprising:
a) a surfactant aggregate having an average aggregate diameter; and
b) a polymer having an alkyl chain having at least 8 carbon atoms in length and having an average particle diameter in which the average particle diameter is the same or smaller than the average aggregate diameter, wherein the polymer is selected from the group consisting of:
poly (styrene-co-maleic anhydride) having a styrene: maleic anhydride ratio of 3:1 and a Mw of 130,000 g/mol,
poly (styrene-co-maleic anhydride) having a styrene: maleic anhydride ratio of 2:1 and a Mw of 7,500 g/mol,
poly (styrene-co-maleic anhydride) having a styrene: maleic anhydride ratio of 3:1 and a Mw of 9,000 g/mol,
poly (styrene-co-maleic anhydride) having a styrene: maleic anhydride ratio of 2:1 and a Mw of 22,000 g/mol,
polymethacrylate, di-isobutylene-co-maleic acid (DIBMA), styrene carbamate block co-polymers, and styrene maleimide block co-polymers,
provided that when the surfactant is selected from the group consisting of: 2-[4-(2,4,4-trimethylpentan-2-yl)phenoxy]ethanol (C14H22O(C2H40)n (n=9-10)), 2-[4-(2,4,4-trimethylpentan-2-yl)phenoxy]ethanol (C14H22O(C2H4O)n (n=30)), N-dodecyl-beta-D-maltoside (DDM), sodium oleate, sodium cholate, sodium deoxycholate (DOC), beta-octyl glucoside (Beta-OG), lauryl dimethylamine n-oxide (LDAO), then the polymer is not selected from the group consisting of: poly(Styrene-co-maleic anhydride) having a styrene: maleic anhydride ratio of 2:1 and a Mw of 7,500 g/mol, poly(Styrene-co-maleic anhydride) having a styrene: maleic anhydride ratio of 2:1 and a Mw of 22,000 g/mol, and Di-isobutylene-co-maleic acid (DIBMA).
