Maitiro uye Sainzi yeMicheka Yehutano Inorwisa Mabhakitiriya
Mhando dzeMishonga Inorwisa Utachiona
Pandinotarisa sainzi iri mubazi rezvehutano, ndinoona zvakasiyana-siyana zvemishonga inorwisa utachionakubasa. Chinhu chimwe nechimwe chinoshandisa nzira yakasiyana yekumisa kana kuuraya utachiona hunokuvadza. Heino tafura inoratidza zvinhu zvinonyanya kushandiswa, mashandiro azvo, uye kuti ndeapi mafiber azvinorapa:
| Mushonga wekurwisa utachiona | Maitiro Ekuita | Mafiber Anoshandiswa Zvakajairika |
|---|---|---|
| Chitosan | Inodzivirira kugadzirwa kwemRNA uye inovhara kutakurwa kwezvinhu zvakakosha zvinosanganiswa | Donje, Polyester, Waya |
| Simbi neMunyu weSimbi (semuenzaniso, sirivha, mhangura, zinc oxide, titanium nanoparticles) | Inogadzira mhando dzeokisijeni dzinoshanda; inokuvadza mapuroteni, mafuta, uye DNA | Donje, Polyester, Naironi, Waya |
| N-halamine | Inokanganisa ma enzymes emasero uye maitiro ekugadzirisa muviri | Donje, Polyester, Naironi, Waya |
| Polyhexamethylene Biguanide (PHMB) | Inokanganisa kusimba kwemasero | Donje, Polyester, Naironi |
| Makomputa eAmmonium eQuaternary | Inokuvadza membrane yemasero, inoparadza mapuroteni, uye inodzivisa kugadzirwa kweDNA | Donje, Polyester, Naironi, Waya |
| Triclosan | Inovhara kugadzirwa kwemafuta uye inokanganisa membrane yemasero | Polyester, Naironi, Polypropylene, Cellulose Acetate, Acrylic |
Ndinowanzoona simbi dzakadai sesirivha nemhangura zvichishandiswa mumayunifomu echipatara uye mumagumbeze. Mishonga iyi inobatsira kuderedza kupararira kwebhakitiriya nemavhairasi mujira rehutano. Makomputa eQuaternary ammonium ne chitosan zvinowanikwawo muzvigadzirwa zvakawanda zvevarwere nevashandi vezvehutano.
Cherechedza:Miyedzo yekuedza yakaita seAATCC 100, ISO 20743, uye ASTM E2149 inobatsira kuyera kuti ma agents aya anoshanda sei mumamiriro ezvinhu chaiwo.
Maitiro Anoita Mishonga Kukanganisa Kukura Kwemabhakitiriya
Ndinoona kuti mishonga inorwisa utachiona inoshandisa nzira dzakasiyana siyana kudzivirira hutachiona kuti husakure paganda rehutano. Heano mamwe emabasa makuru ayo mishonga iyi inoshanda nawo:
- Dzinorwisa madziro emasero kana ma membrane ebhakitiriya, zvichiita kuti masero aputike kana kubuda mvura.
- Zvimwe zvinhu, zvakaita sesirivha nanoparticles, zvinoburitsa maion anovhiringidza mapuroteni neDNA mukati mehutachiona.
- Zvimwe zvakaita sechitosan zvinovhara kugona kwehutachiona kugadzira mapuroteni matsva kana kutakura zvinovaka muviri.
- Zvimwe zvinhu zvinogadzira mhando dzeokisijeni dzinokanganisa zvikamu zvakakosha zvehutachiona, zvichikonzera kufa kwemasero.
- Kurapa kwakagadzirwa nema enzyme kunogona kuputsa zvidimbu zvekudzivirira zvehutachiona, zvichiita kuti zvive nyore kuuraya.
Miedzo yemurabhoritari inosimbisa zviito izvi. Semuenzaniso, ndakaona zvidzidzo apo machira akarapwa nesilver kana zinc oxide nanoparticles anoratidza kushanda kwakasimba kurwisa mabhakitiriya akaita seE. coli neStaphylococcus aureus. Masayendisiti anoshandisa maturusi akadai se scanning electron microscopy kuti vaone kuti mishonga iyi inoramba yakabatana nejira uye inoramba ichishanda mushure mekusuka. Miedzo yakajairika, yakaita seiya inobva kuAmerican Association of Textile Chemists and Colorists, inobatsira kuona simba uye kugara kwenguva refu kwemishonga iyi.
Kubudirira uye Kugara Kwenguva refu
Ndinogara ndichitsvaga jira rekuchengetedza hutano rinoramba richishanda mushure mekushandiswa kakawanda uye kuwachwa. Mishonga yakanakisisa inorwisa utachiona inoratidza kushanda zvakanaka pakurwisa mabhakitiriya akasiyana-siyana, kunyangwe mushure mekuvhiyiwa. Tafura iri pazasi inoratidza mashandiro anoita mishonga yakasiyana-siyana isati yavhiyiwa uye mushure mekuvhiyiwa:
| Mushonga wekurwisa utachiona | BR inopesana neE. coli (%) | BR inopesana neK. pneumoniae (%) | BR inopesana neMRSA (%) | BR mushure mekuvhiyiwa kuti isaparare paE. coli (%) | BR mushure mekuvhiyiwa kuti isaparare paK. pneumoniae (%) | BR mushure mekuvhiyiwa MRSA (%) |
|---|---|---|---|---|---|---|

| Mafuta emuti wetii | 100 | 100 | 99.13 | 100 | 97.67 | 23.88 |
Ndinoona kuti zinc chloride nesilver nitrate zvinochengetedza simba razvo rekuuraya utachiona kunyangwe mushure mekupiswa. Mafuta emuti wetii anoshandawo zvakanaka, asi mamwe mishonga, senge mamwe ma quaternary ammonium compounds, anorasikirwa nesimba rawo mushure mekupiswa. Zvidzidzo zvenguva refu zvinoratidza kuti kuputira ne copper oxide ne graphene oxide kunogona kuramba kuchiuraya mabhakitiriya kwemwedzi inosvika mitanhatu. Mune imwe ongororo, machira aya akarapwa akaramba achishanda ne96% pakurwisa E. coli mushure memwedzi mitanhatu yekushandiswa.
Kuedzwa kwekiriniki kunotsigira zvakawanikwa izvi. Semuenzaniso, mapillowcases emuchipatara nemachira akafukidzwa nemishonga inorwisa utachiona akachengetedza huwandu hwemabhakitiriya huri pasi pehutsanana mushure mevhiki yekushandiswa. Izvi zvinoratidza kuti kurapwa kwakakodzera kwemishonga inorwisa utachiona kunogona kuita kuti machira ekuchengetedza hutano ave akachengeteka uye akavimbika kune varwere nevashandi.
Kushandiswa, Mabhenefiti, uye Remangwana reTekinoroji Yejira Rehutano
Nzira dzekubatanidza muMachira eHutano
Ndakaona nzira dzinoverengeka dzinoshanda dzekuwedzeramishonga inorwisa utachionaNzira idzi dzinobatsira kuchengetedza jira rakachengeteka uye rinogara kwenguva refu.
- Matekiniki ekuputira akadai sekudip-coating, spray-coating, uye electrospinning anoshandisa zvinhu zvinosvibisa pamusoro pejira. Electrospinning inogadzira nanofibers dzinowedzera simba rekuuraya utachiona.
- Kuiswa mumafaibha panguva yekugadzira zvinhu zvinosunga makiyi mukati, zvichiita kuti jira rigare kwenguva refu uye risingatsvedzi.
- Kupedza kurapwa kwakadai sekurapa kweplasma kunovandudza kuti mishonga inonamira zvakanaka sei pajira.
- Tekinoroji dzekugadzira nano-coating dzinoisa zvinhu zvinokuvadza padanho remamorekuru, izvo zvinobatsira kudzivirira kubuda kwechinhu uye kuchengetedza jira richishanda zvakanaka.
- Zvidimbu zvesirivha, maion emhangura, uye quaternary ammonium compounds zvinoshanda zvakanaka uye zvinogara kwenguva refu mushure mekusukwa kakawanda.
- Zvipatara zvinoshandisa machira ayavakashuma kuti hutachiona hushoma uye nzvimbo dzakachena.
- Miedzo yakajairika yakaita seAATCC 100 neISO 20743 inoongorora kuti machira aya anoramba achishanda zvakanaka uye akachengeteka.
Kuchengetedzeka, Kutevedzera Mutemo, uye Mhedzisiro Yechokwadi
Ndinogara ndichitarisa kuti jira rekuchengetedza hutano rinotevedzera mitemo yakasimba yekuchengetedza. Machira aya anofanira kunge akachengeteka paganda, asina chepfu, uye asina utachiona. Anofanira kumisa hutachiona uye kudzivirira kukonzera allergies. Mitemo nemirairo yepasi rose zvinoita kuti machira aya adzivirire varwere nevashandi.
- Mishonga inobva mumiti inopa nzira dzakachengeteka uye dzisingakuvadzi ganda.
- Mishonga inorwisa utachiona inoderedza utachiona, hwema, uye kukuvara kwemachira.
- Mishonga isingakuvadzi nharaunda inoderedza njodzi yekugumbuka uye kusvibiswa kwemuviri.
- Machira aya anobatsira kumisa kupararira kwehutachiona muzvipatara.
Kuongororwa nguva dzose neAATCC 100 neISO 20743 kunoita kuti machira ekuchengetedza hutano arambe achishanda nekufamba kwenguva.
Kufunga Nezvezvakatipoteredza uye Kuvandudza Zvinhu
Ndinofarira nharaunda pakusarudza machira ekuchengetedza hutano. Mamwe machira anogona kusuka nekukuvadza masisitimu emvura. Kushandisa zvinhu zvakasikwa zvinobva mumiti kunoita kuti pave nesarudzo yakachengeteka uye inoora. Machira ekudzivirira anodzivirira utachiona kuti husanamatira, pachinzvimbo chekuauraya, anobatsirawo kuchengetedza nharaunda. Aya mazano matsva anoita kuti machira ekuchengetedza hutano ave akachengeteka kuvanhu nepasi rose.
Ndinoona kuti matekinoroji ekurwisa utachiona mumachira ekuchengetedza hutano anopa dziviriro yakasimba nekumisa hutachiona kukura. Zvipatara zvinoshandisa mhinduro idzi zvinoshuma hutachiona hushoma. Kudzora hutachiona kunotungamirirwa nedata, sezvakaita kuVanderbilt University Medical Center, kunoratidza kudzikira kwehuwandu hwehutachiona. Ndinotarisira kuti kufambira mberi kutsva kucharamba kuchiita kuti machira ekuchengetedza hutano agare akachengeteka uye achishanda zvakanaka.
Mibvunzo Inowanzo bvunzwa
Chii chinoita kuti jira rekuchengetedza hutano risiyane nejira remazuva ese?
Ndinoona jira rinorwisa utachiona serinokosha nekuti rinodzivisa hutachiona kukura. Jira remazuva ese harina dziviriro iyi.
Mishonga inorwisa mabhakitiriya inogara kwenguva yakareba sei pajira rehutano?
Ndinoona kuti kurapwa kwakawanda kunotora nguva yakawanda yekugeza. Mamwe anoramba achishanda kwemwedzi mitanhatu, zvichienderana nemushonga uye nzira yekugeza nayo.
Machira anorwisa utachiona akachengeteka here kune ganda rinotapukira?
Ndinogara ndichitarisa kuti zvakachengeteka here. Machira mazhinji ekurapa anoshandisa mishonga isingakuvadzi ganda. Ndinokurudzira kutsvaga zvigadzirwa zvakaongororwa kuti zvine allergies uye kutsamwa.
