The present invention provides a formulation to link protein to a solid support that comprises one or more proteins, Oligo-dT and one or more non-volatile, water-soluble protein solvents, solutes or combination thereof in an aqueous solution. Further provided is a method of attaching a protein to a surface of a substrate. The formulations provided herein are contacted onto the substrate surface, printed thereon and air dried. The substrate surface is irradiated with UV light to induce thymidine photochemical crosslinking via the thymidine moieties of the Oligo-dT.

METHOD FOR ORGANIZING INDIVIDUAL MOLECULES ON A PATTERNED SUBSTRATE AND STRUCTURES ASSEMBLED THEREBY

Embodiments of the present invention relate to bistable devices constructed using a polynucleotide platform for sensing molecular events including binding or conformational changes of target molecules. Applications include measuring concentration of a target, measuring the effect of environmental conditions on the target, and screening a library for molecules that bind the target or modulate its function. In embodiments, devices include: a top lid, bottom lid, and flexible linker or hinge between them. A device has an open configuration in which the top and bottom lid are separated, and a closed configuration they are bound close together. Binding domains or variations of the target molecule are fixed to a device so that when the molecular event occurs, the device switches from open to closed, or vice versa. Aspects relate to detecting device geometry using, for example, an optical, electronic, magnetic, or DNA signal.

High surface area coatings for solid-phase synthesis

High surface area coatings are applied to solid substrates to increase the surface area available for solid-phase synthesis of polymers. The high surface area coatings use three-dimensional space to provide more area for functional groups to bind polymers than an untreated solid substrate. The polymers may be oligonucleotides, polypeptides, or another type of polymer. The solid substrate is a rigid supportive layer made from a material such as glass, a silicon material, a metal material, and plastic. The coating may be thin films, hydrogels, microparticles. The coating may be made from a metal oxide, a high- dielectric, a low- dielectric, an etched metal, a carbon material, or an organic polymer. The functional groups may be hydroxyl groups, amine groups, thiolate groups, alkenes, n-alkenes, alkalines, N-Hydroxysuccinimide (NHS)-activated esters, polyaniline, aminosilane groups, silanized oxides, oligothiophenes, and diazonium compounds. Techniques for applying coatings to solid substrates and attaching functional groups are also disclosed.
