Abstract: Biological chemicals, potentially found in blood are measured by collecting sweat and determining the concentration or meaning of the selected chemical in sweat. The sweat can be collected using a time based, interval collector 10 and analyzed using an external device. It can also be collected on a one time basis, using a flexible, chemical capacitor 50, or on a continuous basis using a chemical, field effect transducer 98.

Abstract: Described herein is a method, system and computer program for analyzing a colorimetric assay that includes obtaining an image of the assay, optionally correcting for ambient lighting conditions in the image, converting the intensity data for at least one of the red channel, the green channel, or the blue channel to a first data point, recalling a predetermined standardized curve, comparing the first data point with the standardized curve, and identifying the value for the assay parameter from the standardized curve.

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: The focus of this invention is the combined use of: i) one or more biological agents to promote the precipitation of one or more desired solids onto ii) a biologically-assembled 3-D microscale-to-nanoscale structure. That is, the solid precipitation and the 3-D structural assembly are both conducted with the aid of biology. The biologically-derived 3-D structures may assembled by a biological organism, by a component of a biological organism, by a biological molecule, or by combinations thereof. One or more biological agents is/are used to promote the precipitation of one or more new solids onto the biologically-derived 3-D structure.

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 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.
