Sanadihii la soo dhaafay, tignoolajiyada nano-daroogadu waa tignoolajiyada cusub ee caanka ah ee tignoolajiyada diyaarinta daroogada. Daawooyinka Nano sida nanoparticles, kubbadda ama nano kaabsulka nanoparticles sida nidaamka side, iyo waxtarka qayb ka mid ah hab gaar ah wada jir ah ka dib markii daawada, sidoo kale waxaa si toos ah loo samayn karaa in processing farsamada ee nanoparticles.
Marka la barbardhigo dawooyinka caadiga ah, nano-daroogadu waxay leeyihiin faa'iidooyin badan oo aan la barbar dhigi karin daawooyinka caadiga ah:
Daroogada si tartiib ah u sii dayn, beddeleysa nolosha nuska ah ee daroogada ee jirka, sii dheereynta waqtiga waxqabadka daroogada;
Xubin bartilmaameed gaar ah ayaa la gaari karaa ka dib marka laga dhigo daroogo la hagayo;
Si loo yareeyo qiyaasta, la yareeyo ama la baabi'iyo waxyeellada sunta ah ee hoos yimaada dhismaha hubinta waxtarka;
Habka gaadiidka xuubka ayaa loo beddelaa si loo kordhiyo qulqulka daawada ee biofilm, taas oo faa'iido u leh nuugista daawada transdermal iyo ciyaarta waxtarka daroogada.
Markaa baahiyahaas iyadoo la kaashanayo side si ay dawooyin u gaarsiiyaan bartilmaameedyo gaar ah, sii ciyaarta doorka daaweynta ee nanodrugs, naqshadeynta side si loo hagaajiyo waxtarka bartilmaameedka daroogada waa muhiim.
Dhawaan wargayska news ayaa sheegay in jaamacadda New South Wales, Australia, cilmi-baarayaashu waxay soo saareen hab cusub, waxay bedeli karaan qaabka nano daroogada side, tani waxay kaa caawin doontaa gaadiidka daawooyinka ka hortagga kansarka ee lagu sii daayo burada, hagaajinta saameynta anti-bararka. -daawoyinka kansarka.
Unugyada polymer-ka ee xalka si toos ah ayaa loo samayn karaa qaab-dhismeedka spherical spherical vesicle godan, waxay leedahay faa'iidooyinka xasilloonida xooggan, kala duwanaanta shaqeynta ayaa si ballaaran loo isticmaalaa sida side daroogada, laakiin, marka la barbardhigo, sida bakteeriyada iyo fayraska dabiiciga ah waa tuubooyinka, ulo. , iyo qaab-dhismeedyada bayooloji ee aan spherical-ka ahayn waxay si fudud u geli karaan jirka. Sababtoo ah xuubka polymer-ka way adag tahay inay sameeyaan qaab-dhismeed aan spherical ahayn, tani waxay xaddidaysaa awoodda polymer-ka si uu daroogo u gaarsiiyo meesha uu u socdo ee jidhka bini'aadamka ilaa xad.
Cilmi-baarayaasha Australiyaanka ah waxay isticmaaleen microscopy cryoelectron si ay u eegaan isbeddelada qaabdhismeedka molecules-ka polymer ee xalka. Waxay ogaadeen in marka la beddelo xaddiga biyaha ee dareeraha, qaabka iyo cabbirka xuubka polymer-ka lagu hagaajin karo iyada oo la beddelayo xaddiga biyaha ee dareeraha.
Qoraaga hormuudka ah ee daraasadda iyo jaamacadda machadka kimistariga ee pine parr sol, ayaa yidhi: "Horumarkani waxa uu ka dhigan yahay in aanu soo saari karno qaabka polymer vesicle laga yaabo in uu beddelo deegaanka, sida oval ama tubular, iyo xirmada daroogada ee ku jirta." Caddaynta hordhaca ah waxay soo jeedinaysaa in sidayaal badan oo dabiici ah, kuwa aan ahayn nano-daroogadu ay u badan tahay inay galaan unugyada burooyinka.
Cilmi-baadhistan ayaa lagu daabacay khadka internetka cadadkii ugu dambeeyay ee joornaalka isgaarsiinta dabeecadda.
