Ramangwana rekurapwa kwegomarara richava nemarobhoti mini pamutsetse wepamberi 1o3hs

O remangwana rekurapa cancer yakawana mubatanidzwa mutsva mumakore mashoma apfuura, kunyanya nekuvandudzwa kwetekinoroji uye neakakurumbira nanotechnology. Ikozvino bhizimusi imhando yerobhoti mini inogona kuendesa mishonga kuuropi kurwisa mamota mudunhu. Kune vanhuwo zvavo, zvinoita sezviri nyore, zvisingashamisi; zvisinei, kuongorora kwakadzama kunoratidza kuti uropi ndeimwe yenzvimbo dzinenge dzisingakwanisi kuwana, kana kuburikidza neropa kana kunyange kushandisa mamwe marobhoti madiki emushonga - izvi zvinoitika nekuda kwechimwe chipingamupinyi mumuviri. 5l434y

Kufona kwe ropa-uropi chipingamupinyi, ine basa rekuchengetedza iyo Central Nervous System (CNS, kune avo vanojairana nayo) kubva kune zvine chepfu uye vanogona kupinda nechisimba, zvakare kuchengetedza zvinovaka muviri uye zvimwe zvinobatsira zvikamu. Dambudziko nderekuti izvi zvinoita kuti kutungamira kwakananga kwemishonga inopesana, semuenzaniso, mamota europi kusagoneke, zvichiita kuti kurapwa kweiyi fomu yegomarara kukanganiswa.

Rimwe dambudziko nemabundu ehuropi nderekuti mavhiya anodiwa kuti abvise nyama ine hutachiona anopinda sei. Pamusoro pekuve nengozi zvakanyanya, maoparesheni, sekutonga, anongokwanisa kubvisa 90% yemamota aripo munharaunda, chaizvo nekuti chirwere chinopararira munzvimbo ine njodzi. Nanotechnology, saka, inoshandiswa kuedza kugadzirisa matambudziko aya uye kuve nechokwadi chekubudirira mukubvisa mapundu, sezvazvakaita neiyo mini robot nyowani inogona kupa chirevo chitsva kune ramangwana rekurapa cancer.

Tinogona sei kupa chirevo chitsva kune ramangwana rekurapa cancer? 2g562e

Kusvika panguva iyoyo, kutakurwa kwezvinhu zvekurwisa mamota muuropi kwaisashanda. Munguva pfupi yapfuura, zvakadaro, chidzidzo chakaitwa nevatsvagiri veChinese chinogona kuchinja mutambo: kuvharidzira mini robhoti ine membrane ye Escherichia coli - mabhakitiriya anowanikwa mumatumbo edu - uye achiishandura kuva Trojan horse, vatsvakurudzi vakakwanisa kuisa chiduku chiduku muhuropi hwemakonzo e laboratory.

Zvakakosha kucherechedza kuti tsvagiridzo ichiri mumatanho ekutanga, zvinoreva kuti bvunzo pavanhu zvinotora nguva. Kunyangwe zvakadaro, zvinonakidza kuona kuti tekinoroji iri kuuya kusvika papi, kunyanya munzvimbo yehutano. Hazvishamisi, takanga tine akati wandei marobhoti akaunzwa kuCES 2021 yakanangana nezvido zvinomuka panguva yedenda. Chero zvazvingava, kana zvidzidzo zvikaitwa muvanhu, tichava nehondo huru mu remangwana rekurapa cancer.

Iyo mini robhoti inoshanda sei? 3u4t67

Chinhu chekutanga chekufunga nezve kufamba zvemichina midiki. Mini marobhoti haisi chinhu chitsva munyika yezvokurapa (zvichida kwete nguva pfupi yadarika) - mamwe atoshandiswa kugadzirisa diki diki kukuvara kwemukati, kugovera mishonga zvakanyanya mune imwe dunhu uye mamwe mabasa akafanana. Ivo vanofamba vachishandisa magnetism, photovoltaic simba uye vanotozviwana ivo pachavo kuburikidza neruzha.

Hazvina kunyanya kusiyana nerobhoti yakaongororwa nechikwata cheChinese; Musiyano uri pakuti inokwanisa sei kukunda chipingamupinyi cheropa-uropi. Kudanwa neutrobot, mukuremekedza nzira iyo inozvivhara nayo mu neutrophils, robhoti rakagadzirirwa mumatanho matatu anokosha anogona kubatsira mune ramangwana rekurapa kenza:

1. Kugadzira a nano magnetic gel nemishonga ichashandiswa nerobhoti diki;
2. Putira robhoti nenano gel mune a membrane de E. coli kuitira kuti immune system ione sekutyisidzira;
3. Ratidza mudiki kune a neutrophil - chikamu chemasero edziviriro immune system - kuitira kuti igone kuita phagocytose uye, nekudaro, kupinda neutrophil.

Ndosaka zita remadunhurirwa rekuti Trojan horse rakashandiswa. Neimwe nzira, iwe unogona kufunga kuti mini robhoti iri kupinza mishonga muchivharo chinodzivirira iyo Central Nervous System, yakapihwa kuti inozvivanza semabhakitiriya kuti ave phagocytosed uye, nekudaro, inova chikamu cheneutrophil uye, ipapo chete, kuwana. kupinda kune "rumwe rutivi" rwechipingamupinyi chambotaurwa. Sekureva kwechinyorwa, marobhoti madiki akakwanisa kuendesa mishonga kumamota emakonzo, inotova nhanho hombe.

Kupinda mukati mukati nzira yekufambisa zvemarobhoti, tinoona kuti vatsvakurudzi vakakwanisa kudzora kufamba kwemarobhoti mini nekuisa mbeva muimba duku ine magnetic field inofamba. Achishandisa simba remagineti, marobhoti madiki akakwanisa kuita rwendo kuenda kuhuropi chipingamupinyi, achiita achizvimiririra, achingogadziriswa chete kubva kuhuropi. zvaunofunga Munguva chaiyo.

Chimwe chezvipingamupinyi zvikuru pakuvandudza tekinoroji inyaya yekuti marobhoti anogona kudzorwa kana ari mukati boka, asi vaongorori havasati vakwanisa kuwana nzira yekudzora kana kutombovatevera ivo pachavo. Izvi zvinomiririra njodzi pakuti mini robhoti inoburitswa pamuviri nemushonga wakagadzirirwa kuparadza mamota hachisi chinhu chakanaka. Zvinoenderana netsvagiridzo, swarm maitiro (shanduro yemahara) mukuze, sekuronga kunoita chinyorwa) kudivi re neutrobots Inobatsirawo nekumhanya kwekufamba, kukurudzira zviito zvinokurumidza.

Zvichiri kukurumidza kutora shanduko ye nanotechnology kuti ive nyore, kunyanya kana zvasvika kune ramangwana rekurapwa kwegomarara, asi tsvakiridzo yakafanana iri kuitika. kuwedzera kudzokororwa munyika yezvidzidzo, izvo zvinoreva kuti, munguva pfupi, zvishoma zvinhanho zvekuedza zvichaitika uye, nekudaro, kuvandudzwa kwehunyanzvi huchashandiswa kuvanhu kuchavepowo. Uye, hongu, kwete chete emamota, asi zvakanyanya kune zvimwe zvirwere zvakare.

Vatsvakurudzi vanobatanidzwa muchidzidzo ndeiyi:

• Zesheng Li;
• Changyong Gao;
• Xinjian Fan;
• Yuxin Pang;
• Tianlong Li;
• Zhiguang Wu†;
