Abstract: The present investigation presents the synthesis and properties of a new nanogel structure based on poly(itaconic anhydride-co-3,9-divinyl-2,4,8,10-tetraoxaspiro[5.5] undecane) and a low molecular mass gelator, namely riboflavin. The chemical structure of the new network system was confirmed by FTIR and 1H-NMR. The sensitivity of the new structures was evaluated by determining the hydrodynamic radius in interdependence with environmental conditions. The investigation was realized as nanogels are considered very attractive carrier systems owing to their nanometer-sized dimensions, which allow for holding large amounts of solvent and incorporating specific compounds in their nanoscale three-dimensional polymer networks.
Keywords: Itaconic anhydride, spiroacetal moiety, riboflavin, low molecular mass gelator, polymer network.
