Dukurikije ubushakashatsi bushya bwasohotse muri 《 Applied Materials Today》, ibikoresho bishya bikozwe mu tunyabutabire duto cyane bishobora gusimbura ibintu bishobora kwangiza bikoreshwa mu mashereka n'ibicuruzwa by'isuku muri iki gihe.
Abanditsi b'iyi nyandiko, bo mu kigo cy'ikoranabuhanga cy'Abahinde, bavuga ko inyandiko zabo nshya zigira ingaruka nke ku bidukikije kandi ko zifite umutekano ugereranije n'ibyo abantu bakoresha muri iki gihe.
Mu myaka mike ishize, ama-diaper akoreshwa mu gusana, ama-tampon n'ibindi bikoresho by'isuku byakoresheje ama-resin anyuzamo umwuka (SAPs) nk'ibintu binyuzamo umwuka. Ibi bintu bishobora kwinjiza ibiro byabyo inshuro nyinshi mu mazi; Ama-diaper asanzwe ashobora kwinjiza ibiro bikubye inshuro 30 mu mazi yo mu mubiri. Ariko ibyo bikoresho ntibibora: mu bihe byiza, ama-diaper ashobora kumara imyaka 500 agabanuka. Ama-SAP ashobora kandi guteza ibibazo by'ubuzima nka toxic shock syndrome, kandi yabujijwe kuri ama-tampon mu myaka ya 1980.
Ibikoresho bishya byakozwe muri electrospun cellulose acetate nanofibers nta na kimwe muri ibi bibazo gifite. Mu bushakashatsi bwabo, itsinda ry’ubushakashatsi ryasesenguye ibyo bikoresho, bizera ko bishobora gusimbura SAPs zikoreshwa mu bikoresho by’isuku by’abagore.
"Ni ngombwa gushyiraho ubundi buryo bwizewe bwo gusimbura ibicuruzwa biboneka ku isoko, bishobora gutera indwara y’uburozi n’ibindi bimenyetso," Dr Chandra Sharma, umwanditsi w’iyi nyandiko. Turagira inama yo gukuraho ibintu byangiza bikoreshwa mu bicuruzwa bigurishwa ubu n’ibikomoka kuri resine bidashobora kubora hashingiwe ku kudahindura imikorere y’ibicuruzwa cyangwa no kunoza uburyo bikurura amazi n’uburyo biruhura.
Nanofibers ni insinga ndende kandi zoroshye zikorwa n'amashanyarazi. Kubera ubuso bwazo bunini, abashakashatsi bemeza ko zifata neza kurusha ibikoresho bihari. Ibikoresho bikoreshwa mu ma tampons agurishwa bikozwe mu nsinga zirambuye, zifite imigozi hafi mikoroni 30 inyuma. Nanofibers zo, ku rundi ruhande, zifite ubugari bwa nanometero 150, zikaba nto inshuro 200 ugereranyije n'ibikoresho bigezweho. Ibikoresho byoroshye kurusha ibikoreshwa mu bicuruzwa bihari kandi bisiga ibisigazwa bike nyuma yo kubikoresha.
Ibikoresho bya nanofiber nabyo bifite imyenge (birenga 90%) ugereranije n’ibisanzwe (80%), bityo birushaho kwinjiza. Hari ikindi kintu gishobora kuvugwa: hakoreshejwe ibizamini by’inkari za saline n’iz’ubukorikori, insinga z’imyenda zikoresha amashanyarazi zirushaho kwinjiza kurusha ibicuruzwa biboneka ku isoko. Banagerageje ubwoko bubiri bw’ibikoresho bya nanofiber hamwe na SAPs, kandi ibyavuye mu bushakashatsi byagaragaje ko nanofiber yonyine ikora neza kurushaho.
"Ibisubizo byacu bigaragaza ko utwuma duto tw'imyenda dukoresha amashanyarazi dukora neza kurusha ibikoresho by'isuku biboneka ku isoko mu bijyanye no kwinjiza amazi no kuyaruhura, kandi twizera ko ari byiza gusimbura ibintu byangiza biri gukoreshwa ubu," Dr. Sharma yagize ati. "Twizeye ko tuzagira ingaruka nziza ku buzima bw'abantu n'ibidukikije binyuze mu gukoresha no guta ibikoresho by'isuku mu buryo bwizewe."
