Igolide yenye yezona zinto zizinzileyo kwiikhemikhali, kwaye amasuntswana egolide e-nanoscale aneempawu ezikhethekileyo zomzimba kunye neekhemikhali.Kwangoko ngo-1857, iFaraday yanciphisa isisombululo samanzi se-AuCl4 kunye ne-phosphorus ukufumana isisombululo esibomvu se-colloidal ye-nanoppowders yegolide, eyaphula ukuqonda kwabantu ngombala wegolide.Amasuntswana egolide eNano afunyenwe ene-fluorescence, i-supramolecular kunye nepropathi yokuqaphela imolekyuli.Kungenxa kanye ngenxa yeepropathi ezikhethekileyo ze-nano powders zegolide ezinokuthi zibe namathemba okusebenza abanzi kakhulu kwimimandla ye-biosensors, i-photochemical kunye ne-electrochemical catalysis, kunye nezixhobo ze-optoelectronic.Kwiminyaka yakutshanje, ngokusekwe kubume botshintsho olubomvu lwe-plasmon resonance peak ye-Au nanoparticles emva kokubhengezwa, i-DNA kunye neemolekyuli ze-carbohydrate ezilayishwe ngamasuntswana e-nano Au ziye zaphononongwa kwaye zafunyanwa ziluncedo kwimimandla yokugonyeka, ukulinganisa. kunye nomkhondo.

Iinanoparticles zegolidenjengoluhlobo lwe-nanoparticles, luyakhangwa ngokubanzi ngenxa yokuzinza, i-homogeneity kunye ne-biocompatibility.Iipropati ze-plasmon resonance kunye nokudityaniswa kwamasuntswana egolide e-nano, kunye nokuxhomekeka kwawo kwindawo yangaphandle, kubenza basetyenziswe ngokubanzi ekuchongeni umbala.Imikhosi exeliweyo yokuhlanganiswa kwee-Au nano particles ziquka i-hydrogen bonding, i-ionic ligand site interaction, i-metal coordination, kunye ne-host-guest inclusion.Ukusebenzisa i-sodium citrate njenge-stabilizer, i-sodium citrate-modified gold nanoparticles yenziwe ngempumelelo kwaye isetyenziswe njenge-colorimetric probes.Umphezulu we-nano probe yegolide uhlawuliswa kakubi kwaye unokudibaniswa ngokulula kunye neemolekyuli ekujoliswe kuzo ngokufanelekileyo ngokusebenzisa i-electrostatic interaction.Kwisisombululo se-BR buffer kwi-pH 4.6, ipropranolol ihlawuliswa ngokufanelekileyo ngenxa yeprotonation, ngoko inokudibaniswa ne-nanoparticles yegolide, okubangela ukuguqulwa kombala wenkqubo, ukwenzela ukuba kusungulwe indlela yokuchongwa kwe-colorimetric elula yepropranolol.Kwangaxeshanye, ngokudityaniswa komgubo we-nano wegolide, ubunzulu be-RRS benkqubo buya kunyuka, ngoko ke indlela ye-RRS ene-fluorescence spectrophotometer elula njengoko umtshini usekiwe ukuba ubhaqe ngovakalelo ipropranolol.Ngokusekelwe kwi-sodium citrate-modified gold nan oparticles, i-colorimetric kunye neendlela ze-RRS zokumisela ipropranolol zasekwa.

I-Hongwu Nano inexesha elide kunye nokubonelela ngokuzinzileyo kwegolide eliphezulu (Au) i-nano particles, ukuqinisekiswa komgangatho, ukuthengiswa ngokuthe ngqo kwefektri, kunye namaxabiso akhuphisanayo.Nceda ungalibazisi ukunxibelelana nathi ngolwazi oluthe kratya.
