Hemolytic activity of a dental adhesive monomer (N-methacryloyloxy-5-aminosalicylic acid, MASA) and its interaction with phospholipid liposomes as studied by NMR and DSC.

Dent. Mater. J. 11(1) , 17-25, (1992)

N-methacryloyloxy-5-aminosalicylic acid (MASA) has recently been used as an adhesive primer in restorative resin systems. To monitor the biological activity of MASA, we studied changes in NMR-chemical...
