Ubumenyi bwibanze bwa PHA

Polyhydroxyalkanoate (PHA), polyester yo mu nda ikomatanyirijwe hamwe na mikorobe myinshi, ni biomaterial isanzwe ya polymer.

Muri selile mikorobe, cyane cyane selile, hari umubare munini wa polymer polyester - Polyhydroxyalkanoates (PHA).Nibisanzwe bya polymer biomaterial.Ntabwo yerekeza cyane cyane kuri polymer runaka, arikoijambo rusange kumurongo wa polymers ifite imiterere isa nibintu bitandukanye.

PHA ifite uburambeibyiciro bine by'iterambere.

Igisekuru cya mbere cya PHA, polyhydroxybutyrate (PHB), cyakozwe cyane na Chemie Linz AG muri Otirishiya mu myaka ya za 1980 (umusaruro wa toni 100).Nkibintu byavumbuwe kera bya seriveri ya PHA, PHB nuburyo bworoshye kandi busanzwe mumuryango wa PHA.Ifite imiterere ihanitse, imiterere ikomeye kandi yoroheje, kandi imiterere yubukanishi hamwe no gushonga bisa na polypropilene (PP);ariko kurambura kuruhuka Igipimo gito, ubwinshi.Kubwibyo, PHB mubisanzwe ntishobora gukoreshwa nkigikoresho kimwe kandi igomba guhinduka kugirango igere kumikorere ikoreshwa.

Igisekuru cya kabiri cya PHA, polyhydroxybutyric acide copolyester (PHBV), cyacurujwe na ICI mu myaka ya za 1980.PHBV ni kopi ya PHA ifite uburemere burenze 300.000.PHBV, nkiterambere ryibicuruzwa byo mu gisekuru cya mbere PHB, yazamuye cyane ubuhanga bwayo nyuma yo kongeramo 3-hydroxyvalerate (3HV) monomer.Kubera ko ishobora kubora burundu mu ifumbire mvaruganda, mu butaka, mu nyanja n’ibindi bidukikije, ifite kandi biocompatibilité nziza kandi ikora neza cyane kuri liside na gaze, bigatuma PHBV iba ibikoresho byiza byubwubatsi bwabantu kugirango bakore suture yubuvuzi.insinga, imisumari yamagufa, nibindi, kandi birashobora no gukoreshwa nkibiti byubuhinzi,imifuka yo guhaha, ibikoresho byo kumeza nibikoresho byo gupakira ibiryo.Kugeza ubu, uburyo bwo gukora ibicuruzwa bya PHBV bwarushijeho gutera imbere, kandi bwashyizwe mu bikorwa bya golf,ibikoresho byo kumeza, firime, amasahani, gupakira nibindi bice.

Igisekuru cya gatatu cya PHA - poly 3-hydroxybutyrate-3-hydroxyhexanoate (PHBHHx), kuva mu 1998, Laboratoire ya Microbiology University ya Tsinghua na Centre ishinzwe iterambere ry’ibinyabuzima rya Guangdong Jiangmen byateje imbere aside hydroxybutyric ku nshuro ya mbere ku isi Ikoranabuhanga ry’inganda zikora inganda. PHBHHx hamwe na aside hydroxycaproic, kandi ikamenya umusaruro munini.Ugereranije na PHBV, PHBHHx ifite kristu yo hasi kandi ihindagurika cyane, kandi imikorere yayo iragereranywa na plastike ya polyethylene (PE).

Igisekuru cya kane PHA-kopolymer ya poly-3-hydroxybutyrate na 4-hydroxybutyrate (P3HB4HB cyangwa P34HB), ifite imiterere myiza yo gukora firime nibintu byumubiri, ariko hydrophilicity.Igisekuru cya kane PHA yerekanye uburyo bwiza bwo gukoresha mubijyanye nubushakashatsi bwubuhanga bwa tissue, nkibikoresho bya scafold mubukorikori bwamagufwa yo kwipakurura amagufa ya marrow mesenchymal stem selile, nibindi

Kuberako PHA ifite biocompatibilité nziza, biodegradability hamwe nubushyuhe bwo gutunganya amashyuza icyarimwe.Kubwibyo, irashobora gukoreshwa nkibikoresho byubuvuzi kandiibikoresho byo gupakira biodegradableicyarimwe, cyahindutse ahantu hakorerwa ubushakashatsi cyane mubijyanye na biomateriali mumyaka yashize.PHA ifite kandi ibintu byinshi byongerewe agaciro nkibintu bidafite umurongo wa optique, piezoelectricity, hamwe na barrière barrière.
