Abstract:
The claimed invention provides a fusion polypeptide comprising a fibrous protein domain and a mineralization domain. The fusion is used to form an organic-inorganic composite. These organic-inorganic composites can be constructed from the nano- to the macro-scale depending on the size of the fibrous protein fusion domain used. In one embodiment, the composites can also be loaded with other compounds (e.g., dyes, drugs, enzymes) depending on the goal for the materials, to further enhance function. This can be achieved during assembly of the material or during the mineralization step in materials formation.

Abstract:
A method is provided for identifying and isolating peptides capable of binding of inorganic materials such as silica, silver, germanium, cobalt, iron, or oxides thereof, or other materials on a nanometric scale such as carbon nanotubes, using a combinatorial phage display peptide library and a polymerase-chain reaction (PCR) step to obtain specific amino acids sequences. In the method of the invention, a combinatorial phage display library is used to isolate and select the desired binding peptides by a series of steps of target binding of phage with the nanometric material of interest, elution and purification of the bound phages, and amplification using PCR to determine the sequences of phages producing the desired binding peptides. The binding peptides of the invention are particularly advantageous in that they may be used as templates to guide the development of useful structures on a nanometric scale.
Abstract:
A process for producing Gabapentin, (1-(anminomethyl)-1-cyclohexaneacetic acid) from Gabapentin hydrochloride salt. In the process the Gabapentin hydrochloride is converted to Gabapentin using inorganic base such as Barium hydroxide. Gabapentin hydrochloride is converted to Gabapentin sulfate which in turn is converted to free base using Barium hydroxide. The process is directed to improvement in the manufacture of Gabapentin which would be industrially feasible and effective Gabapentin obtained following the process of the invention is suitable as a drug especially in the treatment of cerebral diseases such as epilepsy. The above process involves simple steps and avoid the problems of the known art. In particular the process avoids severe conditions and/or complexities and can be readily adopted for industrial application. The process provides for good yield and does not involve lengthy extended process steps. It is cost-effective and can be carried out involving simple ingredients and steps of manufacture.
Abstract:
An apparatus and method for detecting infrared radiation is provided which comprises a temperature-sensing helical coiled-coil protein such as TIpA, CC1, collagen or myosin, incorporated into an electrically conductive film or gel deposited onto an electrically conductive medium, means for recording changes in conductivity or resistance of the conductive film or gel caused by the presence of infrared radiation and its effect on the thermal-sensing protein, and means to analyze the changes in conductivity or resistance in the conductive film caused thereby so as to determine if infrared radiation is present. By virtue of the present invention, a “biomimetic” infrared sensor is provided which can integrate a recombinantly produced thermally sensitive protein in a conductive polymer matrix, such as a film or gel, and provide a low-cost, lightweight, conformable, and disposable infrared detecting device having high sensitivity and excellent dynamic range.
Abstract:
A method of immobilizing at least one molecule in a silica matrix to form a biosilicification product. The at least one molecule may be immobilized in the silica matrix at substantially the same time as the silica matrix is formed. The method comprises combining at least one silaffin polypeptide, at least one molecule, and at least one hydroxylated water-soluble derivative to form the biosilicification product. The silaffin polypeptide may be Sil1 protein from C. fusiformis, a fragment of the Sil1 protein, poly-L-lysine, or a synthetic polypeptide having affinity for silica. The at least one molecule may be an enzyme, a protein, a polypeptide, an antibody, an antigen, poly(nucleic) acids, microbial cells, plant cells, or animal cells. The hydroxylated water-soluble derivative may be silicic acid.
