Hydrogels ndiwo maratidziro ehydrophilic polymer cheni, anonzi colloidal gels, mune iyo mvura ndiyo inopararira svikiro. -Tatu-dimensional software inokonzerwa nehydrophilic polymer ngetani dzakabatanidzwa pamwechete nekuyambuka-kubatanidza. Nekuda kwekubatanidza-muchinjikwa, iko kusimba kweiyo hydrogel network hakuzo nyungudika nekuwanda kwemvura (doi: 10.1021 / acs.jchemed.6b00389). Hydrogels zvakare anonyanya kupinza (anogona kuve neanopfuura 90% emvura) echisikigo kana ekugadzira epolymer network. Izwi rekuti "hydrogel" rakatanga kuoneka mumabhuku muna 1894 (doi: 10.1007 / BF01830147). Pakutanga, kutsvagisa kwemahydrogel kwakanangana neiyi yakapfava chemakemikari yakabatana nepolymer network kuti iongorore hunhu hwayo, senge kuzvimba / kuzvimba kinetics uye kuenzana, kupatsanura solute, vhoriyamu chikamu shanduko uye inotsvedza kukwesana. Sezvakaita ophthalmology uye kuendesa zvinodhaka. Nekuenderera mberi kwekuvandudza kwekutsvagisa kwegelrogel, tarisiro yayo yakachinja kubva pamyorerwe ari nyore kuenda kune "mhinduro" network. Panguva ino, akasiyana mahydrogel anokwanisa kupindura shanduko mune zvakatipoteredza mamiriro akaita pH, tembiricha, uye magetsi nemagineti minda zvakagadzirwa. Hydrogel actuator inopindura magetsi nemagineti minda inokurudzirwa. Zvisinei, mahydrogels panguva iyoyo aiwanzo nyorovera kana kupwanya mashini, izvo zvaitadzisa zvakanyanya maitiro avo ekushandisa. Nekuuya kwemireniyumu nyowani, mahydrogels akapindawo munguva nyowani, nekuvandudza kwekuvandudza mune yavo michina zvivakwa. Iyi budiriro yakatungamira kune dzakawanda interdisciplinary zvidzidzo zvehydrogels. Mazuva ano, nzira dzakasiyana dzemakemikari dzine masimba ekushandisa simba dzinogona kushandiswa kugadzira mahydrogels akasimba kupfuura mhasuru uye shwashwa. Uye zvakare, inozadzikisawo mamwe mabasa, sekuzviporesa, kuwanda mhinduro, kunamatirana, kunyorova kunyorova, nezvimwewo. Kuvandudza kwekusimba kwesimba rehydrogel kwawedzera zvakanyanya kushandiswa kwesimba iri munzvimbo dzakasiyana siyana, kusanganisira marobhoti akapfava, akagadzirwa nhengo, mushonga wekuvandudza, nezvimwe (doi: /10.1021/acs.macromol.0c00238).
【Chinangwa chikuru】
1. Scaffold munyama mainjiniya (doi: 10.1002 / advs.201801664).

3. Shandisa matsime akafukidzwa nehydrogel yesero tsika (doi: 10.1126 / science.1116995).
4. Mahydrogels anonzwisisa zvakatipoteredza (anonziwo "akachenjera magels" kana "akangwara gels"). Aya mahydrogels anokwanisa kuona shanduko muPH, tembiricha kana metabolite kusungwa uye kusunungura shanduko dzakadai (doi: 10.1016 / j.jconrel.2015.09.011).
5. Injekiseni hydrogel, iyo inogona kushandiswa semutakuri wezvinodhaka kurapwa kwezvirwere kana mutakuri wesero yezvinangwa zvekumutsiridza kana zvinyama engineering (doi: 10.1021 / acs.biomac.9b00769).
6. Yakachengetedzwa kuburitsa zvinodhaka kuendesa system. Ionic simba, pH uye tembiricha zvinogona kushandiswa sekukonzeresa kudzora kuburitswa kwemishonga (doi: 10.1016 / j.cocis.2010.05.016).
7. Ipa kunwa kweiyo necrotic uye fibrotic tishu, kudzikisira uye kudzikisira
8. MaHidrogel anoita kune mamwe mamorekuru (akadai seglucose kana maantigen) anogona kushandiswa se biosensors kana DDS (doi: 10.1021 / cr500116a).
9. Manapukeni anoraswa anogona kupinza weti kana kuisa mumapenji ehutsanana (doi: 10.1016 / j.eurpolymj.2014.11.024).
10. Makore ekubatana (silicone hydrogel, polyacrylamide, silicon-ine hydrogel).
11. EEG uye ECG ekurapa ma electrode anoshandisa mahydrogels anoumbwa nemuchinjikwa-wakabatanidzwa ma polymers (polyethylene oxide, polyAMPS uye polyvinylpyrrolidone).
12. Hydrogel zvinoputika.
13. Rectal manejimendi uye kuongororwa.
14.Kuisa huwandu hwemadota.
15. Mazamu anodyara (kusimudzira zamu).
16. Glue.
17. Zvimedu zvinoshandiswa kuchengetedza hunyoro hwevhu munzvimbo dzakaoma.
18.Madhiresi ekuporesa kutsva kana mamwe maronda akaoma-kupora. Ronda gel rinobatsira kwazvo mukugadzira kana kuchengetedza nzvimbo ine hunyoro.
19. Kuchengetedza zvinodhaka zvekushandisa kwekunze; kunyanya ionic zvinodhaka zvinounzwa neiontophoresis.
20. Chinhu chinofananidza mhuka mucosal tishu, inoshandiswa kuyedza mucosal adhesion zvivakwa zvemushonga wekutakurisa masisitimu (doi: 10.1039 / C5CC02428E).
21. Kugadzirwa kwesimba rinopisa. Kana ichibatanidzwa neion, inogona kudzora kupisa kubva kumagetsi emagetsi nemabhatiri, uye nekushandura kupisa kupisa kuita cheji yemagetsi.
【Kufambira mberi kwedu ikozvino
Parizvino, zvikumbiro zvedu zvehydrogel zvinonyanya kushandiswa mu cosmetology uye kurapwa, uye kuchengetedza chinzvimbo chinotungamira muindasitiri yehydrogel kumba nekune dzimwe nyika maererano nehunyanzvi, uye QA \ QC inoramba yakatsiga.
