Nanostructured model device of energy sensing and monitoring apparatus comprises arrays of orderly nanotubes parallel oriented forming 3D cross-bar with vertically oriented nanopillars membrane through self-assembly affixed onto an electrode; the membrane comprises active sites of an innate Heat Shock Protein (HSP) cross-linked with conductive polymers on an electrode to be able to monitor toxic protein ?-amyloid (A?) energy landscape change, and the reversed membrane potential was restored in the presence of an antibiotic drug. By depositing the HSP60 polymer mixtures on a top of a MMP-2 membrane, it promoted a moonlighting protein network that was able to 97.3% impaired A? refolding with imprecision 0.05%, which was not depending on antibiotic drug's concentration, wherein to be able to maintain the RMP.

A system and method of generating electricity from the salinization of freshwater is provided. In one embodiment, the diffusion of cations and anions from saline to freshwater is rapidly alternated in order to generate electrical power in the form of alternating current. To create pathways for the rapidly alternating diffusion of cations and anions, rhodopsins (light-activated ion channels and pumps) are expressed in bacteria that are growing as a biofilm on a membrane that separates the saline and freshwater. Illumination of the biofilm with blue light permits cation diffusion through cation-permeable channelrhodopsins. Illumination of the biofilm with yellow light permits diffusion of anions through halorhodopsins.

In one aspect, a method for placing carbon nanotubes on a dielectric includes: using DSA of a block copolymer to create a pattern in the placement guide layer on the dielectric which includes multiple trenches in the placement guide layer, wherein there is a first charge on sidewall and top surfaces of the trenches and a second charge on bottom surfaces of the trenches, and wherein the first charge is different from the second charge; and depositing a carbon nanotube solution onto the dielectric, wherein self-assembly of the deposited carbon nanotubes within the trenches occurs based on i) attractive forces between the first charge on the surfaces of the carbon nanotubes and the second charge on the bottom surfaces of the trenches and ii) repulsive forces between the first charge on the surfaces of the carbon nanotubes and the first charge on sidewall and top surfaces of the trenches.
