  • I-Sonication iyindlela ephumelelayo futhi enokwethenjelwa yokwenza izinhlayiya ze-nano flucentres eziphezulu zezinga eliphezulu ezimbonini.
  • I-ultrasonic synthesis ye-fluorescent ye-nano izinhlayiyana ilula, iphephile, i-reproducible futhi ilinganiselwa.

Ultrasonic Ukulungiselela Fluorescent Nano Particles

Ukusetshenziswa kwamagagasi e-ultrasonic ku-nano materials kuyaziwa kahle ngemiphumela yayo ezuzisayo, efaka ukuhlanganiswa kwe-sonochemical kwe-nano izinhlayiya, ukusebenza kwazo nokuguqulwa. Ngaphandle kwalolu hlelo lokusebenza lwe-sonochemical, i-ultrasound yindlela yokukhetha yokusabalalisa okuthembekile nokusebenzayo nokusabalalisa kwe-nano ukumiswa okwesikhashana.

Ultrasonic Ukulungiselela Nanoparticles Fluorescent

I-Ultrasonication iyithuluzi eliqinisekisiwe lokuthuthukisa ukuhlanganiswa kwe-colloidal ye-nanoparticles efana neyodwa kanye ne-crystalline enezinkampani ze-fluorescent, i-quantum esebenza kahle nokuzinza.
I-Ultrasonic isiza ngesikhathi:

I-Water-Soluble Carbon Nanoparticles ene-Fluorescence Up-Conversion

U-Li et al (2010) uye waqala isinyathelo esisodwa I-Ultrasonic indlela yokwenza izinto zenziwe ngokuzenzakalelayo fluorescent enomswakama-amanzi carbon nanoparticles (CNPs). Izinhlayiya ze-fluorescent zenziwe ngokuqondile kusuka ku-glucose nge-one-step alkali noma i-asidi eyasiza ekwelapheni kwe-ultrasonic. Izakhiwo zezinhlayiya zazicebile emaqenjini ama-hydroxyl, ezinikeza phezulu i-hydrophilicity. I-CNPs ingavela elikhanyayo futhi ezimibalabala i-photoluminescence ehlanganisa yonke indawo ebonakalayo ye-infrared (NIR) ye-infrared (NIR). Ngaphezu kwalokho, la ma-CNP abuye ahle kakhulu up-ukuguqulwa kwe-fluorescent izakhiwo.
Inqubo yokusabela ye-single-step-gates eyindlela eyodwa iyindlela eluhlaza futhi elula yokusebenzisa izendlalelo zemvelo ukulungiselela ama-CNP amancane amancane ngokulingana ngokusebenzisa i-glucose njengomthombo wekhabhoni. Umbukiso we-CNPs uzinzile (>Izinyanga eziyi-6) ne-PL eqinile (i-quantum isivuno ∼7%), ikakhulukazi izakhiwo ezimbili ezinhle kakhulu ze-photoluminescent: Ukuphuma kwe-NIR nezakhiwo ze-photoluminescent ze-up. Ukuhlanganisa ukusakazwa kwamahhala emanzini (ngaphandle kokuguqulwa okungaphezulu komhlaba) nezakhiwo ezikhangayo ze-photoluminescent, lawa ma-CNPs athembisa uhlobo olusha lwabamakhisi be-fluorescence, izinzwa ze-bio, imaging biomedical, kanye nokulethwa kwezidakamizwa kwezicelo ku-bioscience ne-nano-biotechnology.

Ukufakelwa kwe-carbon-soluble carbon nanoparticles kusuka ku-glucose nge-one-step alkali noma i-asidi ekwelashwa nge-ultrasonic. (Chofoza ukuze ukhulise!)

(a) Umfanekiso we-TEM we-CNP olungiselelwe nge-sonication kusuka ku-glucose ngobubanzi obungaphansi kuka-5 nm; (b), (c) Izithombe ze-CNPs zihlakazeka emanzini ngelanga kanye ne-UV (365 nm, isikhungo) ukukhanya, ngokulandelana; (dg) I-microscope ye-fluorescent izithombe ze-CNPs ngaphansi kokuncintisana okuhlukile: d, e, f, ne-g ye-360, 390, 470, no-540 nm, ngokulandelana.

I-Fluorescent Porphyrin Nano Izidumbu

Iqembu lokucwaninga likaKashani-Motlagh lenze kahle ngempumelelo porphyrin fluorescent nanoparticles ngaphansi ultrasonication. Ngakho-ke, bahlangene Ukwehliswa kanye ne-sonication. I-tetrakis (para-chlorophenyl) porphyrin eyabangela [i-TClPP nanoparticles] yayisimemezelo esixazululweni ngaphandle kokuhlanganiswa okungenani izinsuku ezingama-30. Ayikho i-self aggregation ye-porphyrin chromophores ehlonishwayo. I-TClPP nanoparticles ibonise izakhiwo ezithakazelisayo ze-optical, ikakhulukazi enkulu abantuchromic shiya ku-spectra ye-absorption.
Ubude besikhathi I-Ultrasonic ukwelashwa kunemiphumela emibi ebunzini bezinhlayiyana ze-porphyrin nanoparticles. Ngesikhathi esincane esifanayo sonication, i-porphyrin nanoparticles ineziqongo eziqine kakhulu kanye nokuxhuma okunamandla; lokhu kubonisa ukuthi ngokukhulisa isikhathi sokunikezwa kwe-sonication, inani le-porphyrin nanoparticles kuba ngaphezulu futhi inani le-porphyrins ngalinye liyanda ukwanda kwe-nanoparticle.

Ukulungiselela i-ultrasonic yezinhlayiya ze-nano fluorescent. (Chofoza ukuze ukhulise!)

Iqembu lokucwaninga likaKashani-Motlagh (2010) lithole i-ultrasonic elula Ukwehliswa umzila wokwenza izinqubo ze-prophyrin nano izinhlayiyana ze-fluorescent.

I-homogenizers ye-ultrasonic isetshenziselwa ukuhlanganiswa kwe-nano izinhlayiya ze-fluorescent

Ukwenziwa kwama-Nanocomposites Magnetic / Fluorescent

Ultrasonically kusiza synthesis of nanocomposites eziqukethe magnetic nanoparticles kanye i-fluorescent ama-quantum amachashazi (i-QDs) nge-revolution ye-silica shell. Lezi zinhlanganisela zibalulekile, ezinezinzuzo zama-QD kanye nama-particle magnetic nano. Amachashazi we-CdS amakhompi ahlanganiswa ngendlela elandelayo: Ekuqaleni, i-2 mL ye-film nucleation engaphansi kwefilimu equkethe i-ferro magnetofluid kanye no-0.5 ml we-1 mol / L CdS amanani amancane ayehlanganiswe ngaphansi I-Ultrasonic ivuselela, i-2 mL PTEOS (itheraethylorthosilicate yangaphambi kwe-polymerized) yabe isetshenziselwa ingxube eyedlule, futhi ekugcineni i-5 mL ammonia yanezelwa.
Ngaphezu kwalokho, ultrasonic emulsification ivumela ukulungiswa kwemibala emisha eminingi emiphakathini ephezulu e-fluorescent-superparamagnetic nanoparticles esebenzisa amachashazi e-quantum (QDS) ne-magnetite nanoparticles kanye ne-poltbutyl acrylate-co-ethyl acrylate-co-methacrylic acid) ye-tribloc copolymer ye-encapsulation.
