Bacteriorhodopsin-embedded purple membranes (PM) have been demonstrated to be a sensitive photoelectric transducer for microbial detection. To efficiently prepare versatile BR-based immunosensors with protein A as antibody captures, a large, high-coverage, and uniformly oriented PM monolayer was fabricated on an electrode as an effective foundation for protein A conjugation through bis-NHS esters, by first affinity-coating biotinylated PM on an aminated surface using a complex of oxidized avidin and graphene oxide as the planar linker and then washing the coating with a shear flow. Three different polyclonal antibodies, each against Escherichia coli, Lactobacillus acidophilus, and Streptococcus mutans, respectively, were individually, effectively and readily adsorbed on the protein A coated electrodes, leading to selective and sensitive quantitative detection of their respective target cells in a single step without any labeling. A single-cell detection limit was achieved for the former two cells. AFM, photocurrent, and Raman analyses all displayed each fabricated layer as well as the captured bacteria, with AFM particularly revealing the formation of a massive continuous PM monolayer on aminated mica. The facile cell-membrane monolayer fabrication and membrane surface conjugation techniques disclosed in this study may be widely applied to the preparation of different biomembrane-based biosensors.

AbstractWe have studied experimental samples of photoelectric transducers with an n ^+– p junction based on a silicon single crystal and an antireflection porous silicon (por-Si) film formed by color chemical etching in a HF : KMnO_4 : C_2H_5OH etcher. It is shown that for KMnO_4 oxidant concentrations of 0.025 and 0.040 M, the por-Si film growth time at which the maximal efficiency of the photoelectric transducer is reached can be substantially increased as compared to that attained using anode electrochemical etching. For investigating the current transmission mechanisms, we have measured the temperature dependence of forward- and backward-bias current–voltage branches. The existence of several current transmission mechanisms has been established. It is found that traps with activation energy distributed in a continuous range of values considerably affect the current transmission.
