Ni ukubera iki kuvura TC bikenewe kubikoresho bikoreshwa mumico?
Hariho ubwoko butandukanye bw'utugingo ngengabuzima, dushobora kugabanywa mu ngirabuzimafatizo zifatika no mu ngirabuzimafatizo mu buryo bw'umuco Ingirabuzimafatizo zahagaritswe ni selile zikura zidashingiye ku buso bw'inkunga, kandi zigakura mu guhagarikwa mu muco, nka lymphocytes Adherent selile ni ingirabuzimafatizo zifatika, bivuze ko imikurire yingirabuzimafatizo igomba kugira ubuso bufatika.Bashobora gukura gusa no kubyara kuri ubu buso bashingiye ku bintu bifatika bifata ubwabo cyangwa bitangwa mu muco.Ingirabuzimafatizo nyinshi ni iz'ingirabuzimafatizo.
Mbere, ibyinshi mu bikoreshwa mu muco w’akagari ku isoko byari bikozwe mu kirahure, cyari hydrophilique, ku buryo ubuso butari bukeneye kuvurwa bidasanzwe Nyamara, mu gihe cyo gukoresha nyirizina, hari ibitagenda neza nko guhumana kandi byoroshye kwanduza icyitegererezo Hamwe iterambere ryihuse rya siyanse n'ikoranabuhanga, ibikoresho bitandukanye bya polymer (nka polystirene PS) byasimbuye buhoro buhoro ibikoresho by'ibirahure bihinduka ibikoresho by'ibanze byo gutunganya umuco w'utugari.
Polystirene ni amorphous random polymer ifite umucyo.Ibicuruzwa byayo bifite umucyo mwinshi cyane, hamwe no kohereza hejuru ya 90%, ibyo bikaba bifasha kwitegereza uko umuco w’akagari umeze kuri microscope.Byongeye kandi, ifite ibyiza byo kurangi byoroshye, gutunganya neza amazi, gukomera no kurwanya imiti yangiza, Nyamara, ubuso bwa polystirene ni hydrophobique.Kugirango tumenye neza ko ingirabuzimafatizo zishobora kwizirika ku buso bw’ibikoreshwa neza, ubuso bw’ibikoreshwa mu muco w’akagari bugomba kuvurwa bidasanzwe.Ibintu bya Hydrophilique bitangirwa hejuru kugirango bihuze no gukura no kubyara ingirabuzimafatizo.Ubu buvuzi bwitwa TC hejuru yubuvuzi TC ikoreshwa mubiribwa byumuco wutugari, ibyapa byumuco utugari, ibyapa bizamuka, amacupa yumuco, nibindi.
Ibiranga ibiryo byumuco utugari nyuma yo kuvura TC hejuru
1. Mbere yo koza ibicuruzwa hejuru: plasma ya O2 irashobora gukuramo uduce duto nizindi myanda ihumanya hejuru yibicuruzwa, hanyuma igakuramo gaze ivanze mucyumba cya vacuum ikoresheje pompe ya vacuum kugirango igere ku ngaruka zabanje gusukurwa.
2. Kugabanya uburemere bwubuso bwibicuruzwa, kugirango impande zoguhuza amazi yibicuruzwa bigabanuke cyane, kandi bihure ningufu zikwiye za ionisation hamwe nibitekerezo, kugirango impande zoguhuza amazi yibicuruzwa WCA <10 °.3 plasma ya O2 izakora muburyo bwa chimique hejuru yibicuruzwa, kandi amatsinda menshi yimikorere arashobora kongerwaho kubicuruzwa, harimo hydroxyl (- OH), carboxyl (- COOH), karubone (- CO -), hydroperoxy (- OOH), nibindi Amatsinda akora arashobora kuzamura umuvuduko wumuco nibikorwa mugihe cyumuco w'akagari.
