Abstract:
The present invention is directed to a fiber optic device consisting of a fiber bundle having multiple legs of silica fibers, using a plurality of microspheres construct to attach target cells, for the assay of cytotoxic compounds. Each leg of silica fibers consists of twenty-five or more silica fibers treated with biotin and streptavidin treated microspheres which chemically bind the microspheres to the silica fibers. Further, the present invention is directed to the unique microspheres. The microspheres have a core, preferably alginate, with an outer surface of chitosan.The present invention is further directed to the use of the described fiber optic device to isolate, research and develop biological medicaments and diagnostic cytotoxic compounds. The fiber optic device utilizes thousands of fibers and the unique microspheres to provide a high-throughput screening device.
Abstract:
Systems and methods employing combinatorial arrays for revealing factors which control biomineralization processes. An understanding of such control factors may be expected to allow those of skill in the art to mimic biomineralization processes so as to allow manufacture of engineered synthetic biomineralized products, such as artificial bones. Such products would be expected to have structure and properties similar or identical to natural products (e.g., bones), and exhibit improved immunological acceptance when implanted as compared to existing synthetic engineered products.

Abstract:
Disclosed is a thermoreversible synthesis of a new type of material made by embedding a colloidal population within a thermo-reversibly gelled polymer. The polymer may be a physically cross-linked PVA hydrogel. PVA hydrogels are non-toxic, biocompatible, mechanically robust, and elastic. The present invention TGCCA diffraction is similar to that of photo-polymerized PCCA. The present invention TGCCA can be irreversibly covalently cross-linked using glutaraldehyde. The cross-linked TGCCA can be made responsive to chemical stimuli by functionalizing the hydrogel hydroxyl groups. The diffraction of carboxyl or amine functionalized TGCCA was monitored as a function of the pH and determined diffraction wavelengths titrate with the pKa of the functional group. It was also demonstrated that TGCCA could be fabricated in arbitrarily large volumes and shapes. The present invention method fabricates inexpensive homogenously diffracting chemically modifiable TGCCA.
Abstract:
Triazine linkers can be used to prepare universal small molecule chips for functional proteomics and sensors. These triazine linker compounds are prepared by making a first building block by adding a first amine by reductive amination of triazine, making a second building block by adding a second amine to cyanuric chloride, and combining the first and second building blocks by aminating the first building block onto one of the chloride positions of the second building block. These triazine linkers are then linked to a substrate for determining binding affinity of proteins.
