摘要:A method and apparatus for selectively applying a print material onto a substrate for the synthesis of an array of oligonucleotides at selected regions of a substrate. The print material includes a barrier material, a monomer sequence, a nucleoside, a deprotection agent, a carrier material, among other materials. The method and apparatus also relies upon standard DMT based chemistry, and a vapor phase deprotection agent such as solid TCA and the like.

摘要:The present invention is on polymers derivatized with an organic deposition-enhancing group for their enhanced deposition onto keratin fibers, especially human hair. The deposition-enhancing group is a di-hydroxyl phenolic compound with a spacer alkyl group bound to a reactive amine or carboxyl group, which reacts with one of the hydroxyl, carboxyl, primary and secondary amine groups on the polymeric backbone. The invention is on the method of synthesizing such compounds and compositions comprising the compounds.
