With the exception of [C 4 mim][CH 3 COO] + DMSO solvent, the solubility of cellulose decreases with increasing alkyl chain length in the order: [C 2 mim][CH 3 COO] + DMSO > [C 6 mim][CH 3 COO] + DMSO > [C 8 …
SpletWhat can dissolve PDMS? Among the commonly used solvents, chloroform, ether, and xylene are highly compatible with PDMS. They have a solubility parameter (SP, d) in the range of 7.3–9.5 cal ½ cm-3 / 2.PDMS will absorb these solvents from a microchannel, and the polymer will saturate with the solvent over time. SpletHere we determined the suitable DMSO concentration for the cryopreservation of human hepatoma HepG2 cells attached to glass and polydimethylsiloxane (PDMS) matrices coated with poly-l-lysine. With the use of the glass matrix, the rate of cell adhesion increased with the DMSO concentration up to 30% v/v in the freezing solution.
