Genomic analysis and drug discovery depend increasingly on rapid, accurate analysis of large sets of sample and extensive compound collections at relatively low cost. By capitalizing on advances in microfabrication, genomics, combinatorial chemistry,

We have performed fast, parallel separations of alleles of the D1S80 locus in a plastic, multi-channel chip, replicated from a microfabricated master and laminated with a plastic film. The array of 16 channels was filled with a replaceable sieving po

Large transitions in viscosity are demonstrated for suspensions of environmentally sensitive gel microspheres upon application of external stimuli. Depending on the number concentration of microspheres, these suspensions may thicken to become semisol

A molecular-thermodynamic analysis is directed toward predicting the partitioning of aqueous proteins into charged hydrogels. This analysis takes into account size exclusion by the network, electrostatic interactions, and the osmotic-pressure differe

Experimental partition coefficients were measured for the distribution of selected proteins and small biomolecules between aqueous, buffered solutions and hydrogels. Temperature-sensitive hydrogels were prepared by polymerizing N-isopropylacrylamide

Sorption of lysozyme by 2-hydroxyethyl methacrylate (HEMA) copolymer hydrogels was studied as a function of pH and gel composition. Three types of HEMA gels were synthesized : neutral (HEMA), acidic (HEMA + acrylic acid), and basic (HEMA + dimethylam

The literature provides several size-exclusion theories to predict solute exclusion by highly swollen hydrogels. Theoretical calculations are compared to the experimental data of Walther et al. (1993) for partitioning of poly(ethylene glycol)s and po

Partitioning data for hexavalent chromium (Cr(VI)) are presented for systems where thermally sensitive poly-N-isopropylacrylamide (NIPA)-based hydrogels are in contact with aqueous solutions of potassium dichromate (K 2 Cr 2 O 7 ). The poly-NIPA hydr

Monte Carlo simulation has been used to study the configurational properties of a lattice‐model isolated polyelectrolyte with attractive segment–segment interaction potentials. This model provides a simple representation of a hydrophobic polyelec
