Ukusetshenziswa kwe-iron oxide emkhakheni we-biomedical

1.Isingeniso

 

I-iron oxide idonse ukunaka okuningi emkhakheni we-biomedical ngenxa ye-superparamagnetism, i-biocompatibility, kanye nokuzinza kwamakhemikhali. Ukuthuthukiswa kwe-nanotechnology kuye kwanweba futhi ububanzi bokusetshenziswa kwe-iron oxide, okuyenza idlale indima ebaluleke kakhulu emkhakheni wezokwelapha.

 

2. Ukusetshenziswa kwe-iron oxide ekulethweni kwezidakamizwa

 

Izinhlayiya ze-Nano iron oxide zingasebenza njengabathwali bezidakamizwa ngenxa yamandla kazibuthe, futhi zingafinyelela ukulethwa kwezidakamizwa okunembile ku-vivo ngokusebenzisa isiqondiso senkundla kazibuthe yangaphandle. Lokhu kungathuthukisa ukusebenza kwezidakamizwa futhi kunciphise umonakalo kumaseli avamile.

 

3. I-ejenti yokuqhathanisa ye-magnetic resonance imaging (MRI).

 

Ama-nanoparticles e-iron oxide, njengama-ejenti ahlukile ku-MRI, angathuthukisa ukugqama kwezithombe futhi asize odokotela babone indawo yesilonda ngokucacile. Ikakhulukazi ekuthwebuleni isimila, ukusetshenziswa kwama-ejenti wokungafani we-iron oxide kuthuthukisa ukunemba kokuxilongwa kusenesikhathi.

 

4. Magnetotherapy

 

Ngokusebenzisa umphumela we-magnetocaloric we-iron oxide nanoparticles, ukushisa kungenziwa ngaphansi kwesenzo sensimu yamagnetic yangaphandle eshintshanayo, ngokukhetha ukubulala amaseli wesimila. Le ndlela inezinzuzo zokungahlaseli kanye nokukhetha okuphezulu.

 

5. Ama-Biosensor

 

Ama-nanoparticles e-iron oxide nawo asetshenziswa njengeziguquli zesignali kuma-biosensors ukuze kutholwe ama-biomolecules afana ne-DNA, amaprotheni, nama-enzyme. Bakhombise amandla amakhulu ekuhlonzweni kwezifo nasekuqaphelweni kwemvelo.

 

6. Ukuphepha kwezinto eziphilayo kanye nobuthi be-iron oxide

 

Nakuba i-iron oxide inemisebenzi eminingi emkhakheni we-biomedical, ukuphepha kwayo kwebhayoloji kanye nobuthi obungaba khona kuseyiyona nto okugxilwe kuyo ocwaningweni. Usayizi, umumo, nokuguqulwa kwendawo yama-nanoparticles kungathinta ukusatshalaliswa kwawo kanye nokugaywa kwe-metabolism ku-vivo.

 

7. Isiphetho

 

I-iron oxide ibonise amandla amakhulu emkhakheni wokusetshenziswa kwe-biomedical, ikakhulukazi ekulethweni kwezidakamizwa, ukuthwebula izithombe, nokwelashwa. Ucwaningo lwesikhathi esizayo ludinga ukuthuthukisa ukwakheka kwama-nanoparticles e-iron oxide, kuthuthukiswe ukusebenza kwawo, futhi kuqinisekiswe ukuphepha kwawo ekusetshenzisweni komtholampilo.

 

8. I-Outlook

 

Ucwaningo lwangomuso lungagxila ekuthuthukiseni ama-nanoparticles e-iron oxide asebenzayo kanye nokuhlola ukusetshenziswa kwawo emithini yomuntu siqu kanye nenembayo. Khonamanjalo, ucwaningo mayelana ne-biocompatibility kanye ne-biodegradability ye-iron oxide luzoqhubeka.
