A method of forming a bioelectronic device including a protein on an electrically conductive substrate, by electrodepositing aminopolysaccharide chitosan on the substrate while applying a cathodic voltage to the substrate, to form an aminopolysaccharide chitosan film thereon, applying an anodic voltage to the substrate in the presence of NaCl to activate the aminopolysaccharide chitosan film so that it is reactive with protein. The method also optionally includes reacting the aminopolysaccharide film, after activation thereof, with the protein, so that the protein assembles on and is coupled to the substrate, thereby forming a bioelectronic device. The protein can include single or multiple protein species, and including biosensing proteins. Additional methods include biosensing of electrochemically active compounds either present in a sample or generated during a biological recognition event and devices useful in such methods. The resulting devices are useful as sensors in hand-held devices, textiles, garments and the like.

Methods for the generation of hydrogels formed by electrodeposition of an electroaddressable polymer are described. The hydrogels may contain one or more cell populations electroaddressed or electroaddressable to a location within the hydrogel and where the cells of the cell populations are entrapped by the hydrogel and are capable of expansion within the hydrogel and may be releasable from the hydrogel. Further provided are electroaddressable polysaccharide blends for the in-film expansion of a cell population, allowing probing of the cells and formation of immunocomplexes. Further provided are methods of using hydrogels containing electroaddressed or electroaddressable cell populations in in-film bioprocessing methods such as cell-based biosensing, protein-based biosensing, and in studies of cell signaling.

In accordance with aspects of the present disclosure, an exemplary system includes a hollow probe having a lumen containing one or more excitation optical fiber(s) and one or more imaging optical fiber(s) where the probe is sized to access a person's body, a first light source optically coupled to the excitation fiber(s) and configured to emit light that excites fluorescence of NADH in breast tissue, a second light source optically coupled to the excitation fiber(s) and configured to emit light that excites fluorescence of FAD in tissue such as breast tissue, an image capturing device optically coupled to the imaging fiber(s), and a controller configured to control the first light source and the image capturing device to capture NADH fluorescence signals/intensities while the probe is within the person's body and control the second light source and the image capturing device to capture FAD fluorescence signals/intensities while the probe is within the person's body.

A novel quantum-based computational process for drug discovery and design was used to identify potential novel liver-stage anti-malarial therapeutic molecules. The approach combined the latest big-data advances in high-throughput bioassay development with fundamental scientific knowledge to generate new pharmaceutical leads. Several molecules with no previous association with anti-parasitical activity were identified. These molecules and there use in prevention and/or treatment of infections are provided.
