Formation of nanogels from alginate-block-dextran copolymer and Ca2+ ions under equilibrium conditions
Alginates are well-known for their capacity to form strong gels in presence of calcium ions. Here, we propose to study the behaviour of hydrophilic diblock copolymers containing alginate and dextran blocks. These copolymers form nanogels with Ca2+ as shown through preliminary experiments by ligh scattering. We will take advantage of the dialysis cell developed by the D22 team to perform the gelation of the copolymers close-to-equilibrium conditions. This will enable us: i) to highlight the mechanism of formation of nanogels, from unimers to final aggregates, ii) to better understand the role of key parameters on the size and morphology of nanogels : the molar mass and composition of BCs, the type of cations (Ca2+, Ba2+, Sr2+) and the dialysis kinetics that can be varied by modifying the pore size of the membrane.
