Microneedle Therapy: Kev Siv Tshuab Evolution Thiab Kev Lag Luam Yav Tom Ntej

Kev Taw Qhia Ntau tshaj li peb xyoo lawm tau dhau los txij li lub tswv yim ntawm kev kho microneedle yog thawj zaug. Nws tau dhau los ua qhov kev hloov kho thev naus laus zis zoo kawg nkaus, hloov zuj zus los ntawm cov silicon microneedles yooj yim thaum ntxov mus rau niaj hnub ntse, programmable advanced systems. Txoj kev txhim kho no tsis yog tsuas yog qhia txog kev nce qib hauv cov ntaub ntawv tshawb fawb, kev tsim khoom thiab biomedicine, tab sis tseem qhia txog kev coj noj coj ua yav tom ntej ntawm kev lag luam kev noj qab haus huv. Daim ntawv no tau tshuaj xyuas keeb kwm kev txhim kho ntawm microneedle thev naus laus zis, tshuaj xyuas thaj chaw thev naus laus zis tam sim no, tshawb nrhiav nws lub luag haujlwm tseem ceeb hauv cov tshuaj kho tus kheej, kev tswj hwm kev noj qab haus huv ntse thiab kev lag luam kev noj qab haus huv, thiab qhia txog yav tom ntej toj roob hauv pes ntawm microneedle sector. ## Evolution of Microneedle Technology ### First Generation: Solid Microneedles (1990s - Early 2000s) Lub tswv yim ntawm microneedle ntxov tshaj plaws hnub rov qab mus rau xyoo 1970, thaum kev sim tshuaj ntsuam xyuas pib hauv 1990s. Xyoo 1998, pab pawg coj los ntawm Mark Prausnitz tau ua pov thawj thawj zaug tias microneedles tuaj yeem txhim kho kev xa tshuaj transdermal. Thawj - tiam microneedles feem ntau yog ua los ntawm cov khoom siv silicon lossis hlau, tsim los ntawm etching thiab microfabrication. Lawv tau tsuas yog siv rau kev kho mob ntawm daim tawv nqaij los txhawb cov tshuaj permeation tom qab, nrog rau kev ua haujlwm ib leeg. Txawm hais tias qhov kev ua tau zoo tau raug txheeb xyuas, lawv raug kev txom nyem los ntawm qhov tsis zoo xws li koob yooj yim tawg, muaj peev xwm seem seem ntawm daim tawv nqaij thiab cov nqi tsim khoom siab. ### Thib Ob Tiam: Coated thiab Dissolvable Microneedles (Ib nrab-2000s - 2010s) Txhawm rau kov yeej cov kev txwv ntawm cov khoom siv microneedles, cov kws tshawb fawb tau tsim coated thiab dissolvable microneedles. Coated microneedles yog loaded nrog tshuaj nyob rau saum npoo ntawm cov khoom koob lub cev; txheej txheej dissolves thiab tso tawm cov tshuaj tom qab kev nkag mus ntawm daim tawv nqaij. Dissolvable microneedles yog tsim los ntawm dej- cov ntaub ntawv soluble xws li hyaluronic acid, gelatin thiab PVP, encapsulating tshuaj thiab dissolving tag nrho tom qab tso nrog tsis muaj kev pheej hmoo ntawm cov seem seem. Cov tiam no tau paub txog kev xa tshuaj sib xyaw ua ke, txhim kho kev nyab xeeb thiab yooj yim heev. Kev tsim cov thev naus laus zis kuj tau nthuav dav los ntawm microfabrication mus rau micromolding, centrifugal casting thiab photopolymerization, txhim kho kev tsim khoom thiab scalability. Kev nce siab ntawm cov microneedles uas tsis tuaj yeem ua rau cov khoom siv hauv tsev microneedle ua tau thiab txhawb nqa lawv daim ntawv thov hauv kev saib xyuas tawv nqaij zoo nkauj thiab kev tswj hwm kev noj qab haus huv hauv tsev. ### Thib Peb: Hollow thiab Stimuli-Responsive Microneedles (Ib nrab-2010s - 2020s) Hollow microneedles ua haujlwm zoo li micro-syringles, ua kom muaj cov tshuaj ua kua dej thiab tsim nyog rau kev tswj hwm qib siab -. Stimuli- teb microneedles, tseem hu ua **smart microneedles**, tuaj yeem hnov ​​​​cov cim ntawm lub cev xws li qabzib, pH thiab cov kab mob inflammatory biomarkers thiab tswj cov tshuaj tso tawm, kos npe rau kev dhia mus rau cov kev xa tshuaj ntse. Cov microneedles no feem ntau yog ua ke nrog stimuli- cov ntaub ntawv teb nrog rau cov thermosensitive, pH-sensitive thiab enzyme-sensitive polymers kom ua tiav ntawm - thov tso tshuaj. Cov txheej txheem tsim khoom tau dhau los ua qhov nyuaj, suav nrog ob-photon polymerization thiab 3D luam ntawv, ua rau kev tsim cov txheej txheem nyuaj xws li barbs, ntau-chamber kab noj hniav thiab cov lus qhia siv rab koob. Cov khoom xaiv tau nthuav dav rau biodegradable polymers, hydrogels thiab nanocomposites, ntxiv nthuav dav daim ntawv thov scenarios. ### Plaub tiam: Kev sib koom ua ke thiab Multifunctional Microneedles (Tam sim no Frontier) Lub cim tshiab ntawm microneedle systems integrates ntau lub peev xwm nrog rau kev hnov, kuaj mob, kho thiab saib xyuas. Piv txwv li, microneedles embedded nrog microsensors tuaj yeem soj ntsuam kev ntsuas lub cev tsis tu ncua xws li qabzib, lactic acid thiab uric acid, thiab xa cov tshuaj los ntawm lub kaw lus kaw - voj voog. Lwm qhov kev tsim kho tshiab suav nrog: - Microneedles rau kev tso tawm ntau yam tshuaj - Electroporation- txhim kho microneedles - Photothermal- teb microneedles - Integrated microneedle Cov no-microfluidic thiab Stretchable microneedles Cov kab ke plooj plooj qhov ciam teb ntawm kev kuaj mob thiab kev kho mob, paub qhov tseeb **theranostic kev koom ua ke**, thiab ua cov cuab yeej muaj zog rau tus kheej cov tshuaj. ## Tam sim no Technological Frontiers thiab Innovation Hotspots ### Material Innovation Materials science yog lub hauv paus tsav tsheb tom qab microneedle nce qib.
