Abstract: A porous hydrogel sensor that is responsive to the presence of one or more target compounds in solution is synthesized based on demixing of certain molecules in the presence of a target compound. The porous hydrogel sensor may include fluorescently tagged antibodies that are noncovalently bound to the gel and then released in the presence of the target antigen. The porous hydrogel sensor may alternatively include dissolvable cross-links using polymerized antibody and antigen complexes so that, in the presence of the target antigen, the cross-links will be displaced and the hydrogel will dissolve.

Abstract: A class of bicyclic brominated furanone structures that have reduced toxicity and high activity for inhibiting biofilm formation and quorum sensing by microbes. The molecules have two fused cyclic alkyl groups that provide a structural framework that retain one or more bromine groups on the structure. The bicyclic furanones have reduced toxicity to mammalian cells as compared to other brominated furanones but retain the ability to inhibit biofilm formation in bacterial populations.

Abstract: A method of, and apparatus for, increasing the power output of the cell using one or more intrinsic oxide buffer layers to reduce extraneous optical absorption. The intrinsic oxide buffer layers can be, for example: (i) an undoped oxide film that is prepared without intentional doping, (ii) a compensated oxide layer that is prepared using compensating dopants to reduce the conductivity of the oxide film, which can be either undoped or doped, and/or (iii) a passivated oxide layer that is prepared using hydrogen or other atoms to improve the electronic properties of low conductivity oxide films.
