Abstract
In evolution of instrumentation for analytical chemistry as crucial technological breakthroughs should be considered a common introduction of electronics with all its progress in integration, and then microprocessors which was followed by a widespread computerization. It is seems that a similar role can be attributed to the introduction of various elements of modern nanotechnology, observed with a fast progress since beginning of this century. It concerns all areas of the applications of analytical chemistry, including also progress in flow analysis, which are being developed since the middle of 20th century. Obviously, it should not be omitted the developed earlier and analytically applied planar structures like lipid membranes or self-assembled monolayers They had essential impact prior to discoveries of numerous extraordinary nanoparticles such as fullerenes, carbon nanotubes and graphene, or nanocrystalline semiconductors (quantum dots). Mostly, due to catalytic effects, significantly developed surface and the possibility of easy functionalization, their application in various stages of flow analytical procedures can significantly improve them. The application of new nanomaterials may be used for the development of new detection methods for flow analytical systems in macro-flow setups as well as in microfluidics and lateral flow immunoassay tests. It is also advantageous that quick flow conditions of measurements may be helpful in preventing unfavorable agglomeration of nanoparticles. A vast literature published already on this subject (e.g. almost 1000 papers about carbon nanotubes and flow-injection analytical systems) implies that for this reviews it was necessary to make an arbitrary selection of reported examples of this trend, focused mainly on achievements reported in the recent decade.

Zhou H, Fu J, Jia Q, Wang S, Liang P, Wang Y, Lv Y, Han S. Magnetic nanoparticles covalently immobilizing epidermal growth factor receptor by SNAP-Tag protein as a platform for drug discovery. Talanta 2022; 240:123204. [PMID: 35026637 DOI: 10.1016/j.talanta.2021.123204] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 12/30/2021] [Accepted: 12/31/2021] [Indexed: 12/31/2022]
Abstract
Magnetic nanoparticles (NPs) cloaked with cell membranes expressing high levels of the epidermal growth factor receptor (EGFR) have been used to screen for EGFR-targeting active compounds in traditional Chinese medicine (TCM) formulations. However, previous strategies involved physical immobilization of the biomaterials on the surface of the nanocarrier, resulting in highly unstable platforms since the biological materials could dislodge easily. Chemical bonding of biomaterials to the nanoparticles surface can improve the stability of the biomimetic platforms. In this study, membrane fragments from cells expressing SNAP-Tag-EGFR (ST-EGFR) were immobilized on the surface of magnetic NPs. The ST-EGFR magnetic cell membrane nanoparticles (ST-EGFR/MCMNs) showed greater stability, and higher binding capacity, selectivity adsorption of gefitinib after 7 days compared to the un-immobilized magnetic cell membrane nanoparticles (EGFR/MCMNs). The ST-EGFR/MCMNs were used to screen for the EGFR-targeting active compounds of Zanthoxyli Radix (ZR), and identified toddalolactone and nitidine chloride. The latter significantly inhibited the proliferation of EGFR-overexpressing cancer cells, and was more effective compared to gefitinib. This innovative technology can be used to rapidly screen for active compounds from complex extracts, and aid in drug discovery.
