Isingeniso

Ucwaningo lwe-biomedical luyindawo ewumnyombo yokuqhubekisela phambili inqubekelaphambili yezokwelapha kanye nokwelashwa kwezifo, okunemiphumela efinyelela kude empilweni yabantu nasekuthuthukisweni komphakathi. Ocwaningweni lwesayensi,izitsha ze-scintillation, njengethuluzi eliyisisekelo kodwa elibalulekile, ukunemba nokuthembeka kunquma ngokuqondile ukunemba nokukhiqizwa kabusha kwemiphumela yokuhlola.

Indlela Izitsha Ze-Scantillation Ezisebenza Ngayo

1. Isingeniso kubuchwepheshe bokubala be-liquid scintillation

• Umgomo oyisisekelo wokutholwa kwe-radioisotope: ama-radioisotopes akhipha amandla ngesikhathi sokubola, futhi la mandla angatholwa futhi asetshenziselwe ukuhlaziya inani
• Indima ye-scintillation fluid: Uketshezi lwe-scintillation luqukethe izinto ze-fluorescent. Lapho izinhlayiya ezinemisebe zihlangana noketshezi lwe-scintillation, amandla ayamuncwa futhi aguqulwe abe isignali yokukhanya (amaphothoni).
• Iqhaza leshubhu le-photomultiplier: Ishubhu ye-photomultiplier ithola amasignali okukhanya akhishwa uketshezi lwe-scintillation futhi iwaguqulele kumasiginali kagesi, agcina erekhodwa futhi ahlaziywe ithuluzi ukuze kutholwe ukutholwa kobuningi be-radioisotopes.

2. Idizayini nezinto zokwakha izitsha ze-scintillation

• Ingilazi: Ukucaca okuphezulu, ukungabi namakhemikhali kwamakhemikhali nokumelana nokushisa okuphezulu, kulungele i-asidi eqinile, i-alkali noma imvelo ye-solvent ye-organic, kodwa ibuthakathaka.
• Ipulasitiki: ingasindi, ayinqamuki futhi ifanele ukusetshenziswa kanye, kodwa ingase ingazinzi ezindaweni ezithile zamakhemikhali.
• Ukungafihli kanye nokuzinza kwamakhemikhali: Ukucaca okuphezulu kuqinisekisa ukudluliswa okuphumelelayo kwezimpawu zokukhanya, kuyilapho ukuzinza kwamakhemikhali kuqinisekisa ukuthi amasampula awangcolisiwe noma awonakaliswa ngesikhathi sokugcina nokuhlolwa.
• Idizayini engavuzi: Iqinisekisa ukuthi amasampula emisebe ngeke avuze, ivikela ukuphepha kokuhlolwa.
• Umklamo wokulwa nokuhwamuka: Ivimbela ukuhwamuka kwesampula futhi iqinisekise ukunemba kwemiphumela yokuhlola.
• Ukumelana namakhemikhali: Zijwayelane nezimo ezihlukahlukene zokuhlola ukuze unwebe impilo yesevisi.

• Uhlelo lokusebenza ekuhlaziyweni kwenkulumo yofuzo: kusetshenziswa ama-probe anama-radiolabeled ukuze kutholwe izinga lokuvezwa kofuzo oluthile nokutadisha indlela yokulawula izakhi zofuzo.

3. Ucwaningo lwezemvelo kanye nobuthi

• Ukuze kutholwe izinto ezingcolisa imisebe endaweni ezungezile: Ukuhlaziywa kobuningi bokungcola okukhipha imisebe emanzini, emhlabathini nasemoyeni ngokubala kwe-liquid scintillation ukuhlola ubungozi bemvelo.
• Okokuhlola imiphumela yebhayoloji yezinto zamakhemikhali ezifundweni ze-toxicological: kusetshenziswa amasu e-radiolabeling ukutadisha izindlela ze-metabolic zezinto zamakhemikhali ezintweni eziphilayo kanye nezindlela zobuthi bazo.

4. Ucwaningo lwezokwelapha lwezokwelapha

• Izicelo ocwaningweni lomdlavuza: ukuze kuthuthukiswe nokuhlolwa kwemithi ye-radiopharmaceuticals, efana namasosha omzimba anelebula le-radioisotope noma izidakamizwa zokwelashwa okuqondiswe kwesimila nokuxilongwa.
• Isicelo ocwaningweni lwe-immunology: ukutadisha indlela yokusabela komzimba kanye nezimpawu zezinto eziphilayo ezihlobene nesifo ngokusebenzisa amasosha omzimba ane-radiolabeled.

Intuthuko Yezobuchwepheshe kanye Nezinto Ezintsha Ezitshalweni Ze-Scantillation

2. Izinhlelo zokusebenza ezingaba khona emithini yomuntu siqu kanye nemithi enembile

• Amathemba ekwelashweni kofuzo kanye nokuthuthukiswa kwezidakamizwa eziyisishiyagalombili: izitsha ze-scintillation zingasetshenziselwa ukuthuthukiswa nokuhlolwa kwama-gene vectors ane-radiolebele noma imithi eqondiwe, ukuhlinzeka ngosizo lobuchwepheshe emithini yomuntu siqu.
• Amandla okusebenza ekuxilongweni kwezifo kusenesikhathi: ngobuchwepheshe bokutholwa kwe-radioactive ebucayi kakhulu, izitsha ze-scintillation zilindeleke ukuba zibambe iqhaza elibalulekile ekuxilongweni kokuqala komdlavuza, izifo ze-neurodegenerative nezinye izifo ezinkulu, futhi zikhuthaze ukuthuthukiswa komuthi onembile.

Isiphetho

Njengethuluzi eliyisisekelo locwaningo lwe-biomedical, izitsha ze-scintillation zidlala indima ebalulekile ekuhloleni okubalulekile okufana nokutholwa kwe-radioisotope nokubala kwe-liquid scintillation, ukuhlinzeka ngosekelo oluthembekile lwezobuchwepheshe lwempumelelo yesayensi. Ngokuthuthuka okuqhubekayo kwesayensi yezinto ezibonakalayo kanye nobuchwepheshe bokutholwa, ukusebenza kwezitsha zokucwenga kuzothuthukiswa, kuqhubeke nokukhuthaza ucwaningo lwe-biomedical ukuze lusebenze kahle futhi lunembile.

Abacwaningi kufanele banake ikhwalithi nokusebenziseka kwamathuluzi okuhlola futhi bakhethe amabhodlela e-scintillation asebenza kahle kakhulu ukuze bathuthukise ukunemba nokukhiqizwa kabusha kokuhlolwa. Izinto ezintsha kanye nobuchwepheshe, njengezinto ezivumelana nemvelo, izinhlelo ezizenzakalelayo namathuluzi okuhlaziya ubuhlakani bokwenziwa, kufanele kwamukelwe ngenkuthalo ukukhuthaza ukusungulwa kwezindlela zokuhlola kanye nokwenza ngcono ukusebenza kahle kocwaningo.
