Abstract
Polymer macroporous monoliths are widely used as efficient sorbents in different, mostly dynamic, interphase processes. In this paper, monolithic materials strongly bound to the inert glass surface are suggested as operative matrices at the development of three-dimensional (3-D) microarrays. For this purpose, several rigid macroporous copolymers differed by reactivity and hydrophobic–hydrophilic properties were synthesized and tested: (1) glycidyl methacrylate -co-ethylene dimethacrylate (poly(GMA -co-EDMA)), (2) glycidyl methacrylate -co-glycerol dimethacrylate (poly(GMA -co-GDMA)), (3) N-hydroxyphthalimide ester of acrylic acid -co-glycidyl methacrylate -co-ethylene dimethacrylate (poly(HPIEAA -co-GMA -co-EDMA)), (4) 2-cyanoethyl methacrylate -co-ethylene dimethacrylate (poly(CEMA -co-EDMA)), and (5) 2-cyanoethyl methacrylate -co-2-hydroxyethyl methacrylate -co-ethylene dimethacrylate (poly(CEMA -co-HEMA -co-EDMA)). The constructed devices were used as platforms for protein microarrays construction and model mouse IgG—goat anti-mouse IgG affinity pair was used to demonstrate the potential of developed test-systems, as well as to optimize microanalytical conditions. The offered microarray platforms were applied to detect the bone tissue marker osteopontin directly in cell culture medium.
