Kub yog ib qho ntawm cov tshuaj muaj zog tshaj plaws, thiab nanoscale kub hais muaj tshwj xeeb lub cev thiab tshuaj.Raws li thaum ntxov 1857, Faraday txo cov AuCl4-dej tov nrog phosphorus kom tau ib tug sib sib zog nqus liab colloidal tov ntawm kub nanopowders, uas ua txhaum tib neeg txoj kev nkag siab ntawm cov xim ntawm kub.Nano kub hais kuj tau pom tias muaj fluorescence, supramolecular thiab molecular paub cov khoom.Nws yog qhov tseeb vim hais tias ntawm cov khoom tshwj xeeb ntawm nano kub hmoov uas lawv muaj cov ntawv thov dav dav hauv cov teb ntawm biosensors, photochemical thiab electrochemical catalysis, thiab optoelectronic li.Nyob rau hauv xyoo tas los no, raws li qhov tshwm sim ntawm qhov liab-hloov ntawm qhov chaw plasmon resonance ncov ntawm Au nanoparticles tom qab adsorption, DNA thiab carbohydrate molecules loaded nrog nano Au particles tau kawm thiab pom tias muaj txiaj ntsig zoo hauv kev tiv thaiv kab mob, calibration. thiab tracer.

Kub nanoparticlesraws li ib hom nanoparticles, yog dav nyiam vim lawv stability, homogeneity thiab biocompatibility.Lub nto plasmon resonance zog thiab aggregation ntawm kub nano hais, raws li zoo raws li lawv dependence rau sab nraud ib puag ncig, ua rau lawv lug siv nyob rau hauv colorimetric qhia.Cov tub rog tshaj tawm rau kev sib sau ua ke ntawm Au nano hais muaj xws li hydrogen bonding, ionic ligand site kev sib cuam tshuam, kev sib koom tes hlau, thiab kev koom nrog tus tswv tsev.Siv sodium citrate ua tus stabilizer, sodium citrate-hloov kub nanoparticles tau ua tiav zoo thiab siv los ua cov tshuaj ntsuam xyuas xim.Qhov saum npoo ntawm nano kub sojntsuam yog qhov tsis zoo thiab tuaj yeem yooj yim ua ke nrog cov txiaj ntsig zoo ntawm lub hom phiaj los ntawm kev sib cuam tshuam electrostatic.Hauv BR buffer tov ntawm pH 4.6, propranolol yog qhov zoo them vim yog protonation, yog li nws tuaj yeem ua ke nrog kub nanoparticles, uas ua rau muaj kev hloov pauv hauv cov xim ntawm lub cev, thiaj li tsim kom muaj ib txoj kev qhia txog xim yooj yim rau propranolol.Nyob rau tib lub sijhawm, nrog kev sib sau ua ke ntawm cov hmoov nano kub, RRS kev siv lub cev kuj tseem yuav nce ntxiv, yog li RRS txoj kev nrog ib qho yooj yim fluorescence spectrophotometer raws li lub detector kuj tsim los soj ntsuam propranolol.Raws li sodium citrate-hloov kub nan oparticles, colorimetric thiab RRS txoj kev rau kev txiav txim ntawm propranolol tau tsim.

Hongwu Nano muaj lub sijhawm ntev thiab ruaj khov ntawm cov khoom zoo kub (Au) nano hais, kev ruaj ntseg zoo, Hoobkas ncaj muag muag, thiab cov nqi sib tw.Thov tsis txhob yig tiv tauj peb kom paub ntxiv.
