摘要： The present invention provides biomimetic sensor devices that utilize proteins - such as G-protein coupled receptors - and are useful in high-sensitivity analysis of analyte-containing samples. These sensors may be used to determine the presence or concentration of one or more analytes in a sample. The invention also includes methods of fabricating the devices and methods of using the devices to assay samples.

摘要： Biomimetic sensor devices that utilize proteins - such as G-protein coupled receptors - and are useful in high-sensitivity analysis of analyte-containing samples. These sensors may be used to determine the presence or concentration of one or more analytes in a sample. Methods of fabricating the devices include Three-terminal transistor circuits were fabricated from carbon nanotubes grown on oxidized silicon substrates by catalytic chemical vapor deposition, with the heavily doped substrate used as a back gate electrode. Methods of using the devices to assay samples include contacting a sample with a device comprising a transmembrane protein disposed in a lipid, an amphiphile, or both, the device comprising a semiconductor material in electronic communication with the transmembrane protein; and measuring a first electronic characteristic of the device when the device is contacted with the sample.

摘要： Membrane proteins are difficult to express in recombinant form, purify, and characterize, at least in part due to their hydrophobic or partially hydrophobic properties. Membrane scaffold proteins (MSP) assemble with target membrane or other hydrophobic or partially hydrophobic proteins or membrane fragments to form soluble nanoscale particles which preserve their native structure and function; they are improved over liposomes and detergent micelles. In the presence of phospholipid, MSPs form nanoscopic phospholipid bilayer disks, with the MSP stabilizing the particle at the perimeter of the bilayer domain. The particle bilayer structure allows manipulation of incorporated proteins in solution or on solid supports, including for use with such surface-sensitive techniques as scanning probe microscopy or surface plasmon resonance. The nanoscale particles facilitate pharmaceutical and biological research, structure/function correlation, structure determination, bioseparation, and drug discovery.
摘要翻译：至少部分由于其疏水或部分疏水性质，膜蛋白难以以重组形式表达，纯化和表征。膜支架蛋白（MSP）与靶膜或其他疏水性或部分疏水性蛋白质或膜片段组装以形成保留其天然结构和功能的可溶性纳米级粒子; 它们比脂质体和洗涤剂胶束有所改进。在存在磷脂的情况下，MSP形成纳米级磷脂双分子层盘，MSP稳定双层区周边的粒子。颗粒双层结构允许在溶液中或在固体载体上操作掺入的蛋白质，包括用于诸如扫描探针显微镜术或表面等离子体共振的表面敏感技术。纳米级颗粒促进了药物和生物学研究，结构/功能关联，结构测定，生物分离和药物发现。
