  • Publication number: 20220018801
    Abstract: 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.

  • Patent number: 9534999
    Abstract: The present invention provides a single cancer direct detection device comprises an electrode having a nanopore biomimetic membrane inducing a bio-communication signal by cancer cells selectively under antibody-free and label-free condition. Methods of detecting cancer cells and monitoring cancer progresses in a contour map format are also discussed. In particular, the cancer cell heat release map comprises multiple variables correlations, a ratio of “Action potential/Resting potential” (RAPRP) as a special biomarker for the variable along with other variables of current or concentration makes visual display cancer progresses possible compared with normal cells which have negligible heat release.

  • Publication number: 20140178925
    Abstract: The present invention provides a novel electrochemical device and a cancer cell heat release map method to visually display the cancer progresses. The novel device comprises an electrode having a nanopore biomimetic electron-relay network with imidazolium-ATP of cancer cell-water-pyridine at the active sites that mimic the electron-relaying between His 516 and N(5)-FAD of GOx for the purpose to selectively detect triple-negative breast cancer cell at single cell concentration and it rejects brain cancer cell. The device is fast in millisecond to detect cancers without sample preparation and without interference from other substances, such glucose and proteins under reagent-free conditions. A unique biomarker of the ratio of “Action/Resting” cell membrane potential can be used to monitor the cancer progress against the normal cells. A visual contour map of a multiple variable correlation method provided to assess the heat release from the cancer cells against the normal cells is presented.
