I-Mass Spectrometry: Imigaqo, izicelo ezinokutsha kunye nezicelo zenguqu kwisayensi yanamhlanje

I-Mass Spectrometry imele phambili kwinzululwazi yohlalutyo, kwaye imvakalelo emangalisayo kunye nokuchaneka kwenze isixhobo esingenakuthintelwa ekuchongeni nasekuthatheni iimolekyuli. Ubuchule busebenza ngokuguqula iisampulu ze-ion kwaye zilinganisa ubunzima bayo (m \ / z) umyinge, uvumela abaphandi ukuba basebenzise izakhiwo zemolekyuli. I-Ms idlala indima ebaluleke kakhulu kwiProtetics, imetamics, impumelelo yeziyobisi, ukubek'esweni okusingqongileyo, kunye nendlela yokuxilongwa kwezonyango. Ukukwazi kwayo ukubonelela ngolwazi lwemolekyuli eneempawu eziphezulu kuyaqhubeka nokuqhuba ubuchule kwinkqubela phambili yenzululwazi eyahlukileyo.

Imigaqo yobunzima ye-spectrometry

I-Mass Spectrometry (ms) yindlela enamandla yohlalutyo esetyenziselwa ukwenza izinto ezaziwayo, chonga izinto ezingaziwayo, kunye ne-Elcifate yemozulu. Kwi-MS, isampulu ye-iosd, kwaye amasuntswana abizelweyo akhutshelwe ahlukaniswe kwaye alinganiswa ngokusekwe kwimilinganiselo yabo yokuhlawula. I-spectrometer yesiqhelo iqulethe izinto ezintathu eziphambili:

• I-Ion yomthombo: kuvelisa i-ions yegesi evela kwiimolekyuli zemolekyuli.

• Umhlalutyi weManzi: usombulula i-ions ngenqanaba labo lokuhlawula.
  

  

• Umcwangcisi: Vula i-ion efundisiweyo kwaye usebenzise ubuninzi babo.

Inkqubo yohlalutyo ibandakanya amanyathelo aliqela:

1. Imveliso ye-ION: isampulu yi-iosd ukuvelisa ii-ions zemolekyuli ezihlawulisiweyo (rhoqo ngeendlela ezifana no-Iontronition okanye i-electropray).

2. Ukwahlulwa kwe-Ion: I-ions icinyiwe okanye yahlulwe ngokwe-M \ / z kwi-hlalutel.

3. Ubuqhetseba (ukuba kuyafuneka): Ukhethwe kwangaphambili i-Ions kunokuqhekeka kwiseli yokungqubana ukuveza ulwazi lwesakhiwo.

4. Ukufunyanwa nokurekhoda: Imiboniso esetyenzisiweyo i-Ions yokugqibela kwaye irekhoda i-spectrum enkulu, i-plan ye-Iyon Discys versing M \ / Z. Le mbonakalo inika ubunzima bemolekyuli kunye nemikhondo yocalulo yohlalutyo.

I-Innovations kwi-spectrometry

Iindlela ze-Iorizoy

Intshayelelo e-Iyotion e-Iyor ineengxaki ze-MS. Umzekelo, i-Ilectropray I-electros I-Nano-Electroptray (i-Nano-TIS) isebenzisa ii-capillaries ezihle kakhulu zokwenza amathontsi amachaphaza avela kwimithamo encinci yesampula, ngaloo ndlela ukuphucula ukuziva uvakalelo kunye nokusonjululwa. Kwi-Laser yeMatrix encedisiweyo \ / uIonis (Maldi), izixhobo zeMatrix zeMatrix ziphucule i-Ionist Equires kunye neSigqibo esiPhakamileyo sibonisa ukucinga kweeproteni, i-metabolites, kunye nee-lipids kumacandelo athile. Iindlela ze-ionsure ze-i-Insorization i-Electropy Ionsul (i-DIA) kunye nohlalutyo ngqo ngexesha lokwenyani (i-DART) limele i-leap top: bavumela iisampulu ukuba zihlaziywe ngqo emoyeni ngaphandle kokulungiselela kakhulu. Ezi ndlela zenza ukuba uhlalutyo olukhawulezileyo, olusekwe kwisiza kwizicelo ze-forensic, ukubeka iliso kwindalo esingqongileyo kunye nolawulo oluphambili.

Itekhnoloji yohlalutyo

I-Innovations kwi-Managezles eninzi iphumelele ubuchule obumangalisayo beMS. Umzekelo, uhlalutyo lwe-orbip lubonelela ngesisombululo se-Uturration, ukuSebenzisa ii-Ions kwintsimi ye-elektrostatic apho i-ofisi ye-ofisi ye-onsestatic khona apho kuvelisa imilinganiselo ye-M \ / ye-z. Izixhobo ze-orbiplap zanamhlanje zinokufezekisa izisombululo ezinzima ngaphezulu kwe-100,000 kwi-Mid-Uluhlu lwee-MARMM M I-4ier-guqule i-ion cyclorlonce ye-Ion ye-Ion (i-FT-ACR ibonelela ngesisombululo esiphakamileyo kunye nokuchaneka ngokuthintela i-ions yemagnetic eqinileyo kunye nokuhlalutya i-cyclogron yentshukumo yabo ye-cyclonron. I-TOF ebonisa i-TOF (i-Mnu-Tof) yandisa indlela yokubhabha ngokusebenzisa izindululo ezininzi, ngakumbi ukonyusa isisombululo se-TOF ngaphandle kokwandisa isixhobo. Iinkqubo ze-hybrid zidibanisa itekhnoloji: I-Qudrupole-Orbbiprap kunye nezixhobo ze-quadrupole-tof zisebenzisa i-quadrupole ukukhetha i-ion kunye ne-orbitrap okanye i-tobrap yokufezekisa isantya esiphezulu, umlinganiso ophezulu. Ezi hybrids zihambisa ukukhetha kunye nokuchaneka kohlalutyo lwesampulu. Ukongeza, i-TESTE YESIBONI I-QQQ isetyenziswa ngokubanzi kwizinto zeprotetiotication kunye nezonyango zeklinikhi zoMlinganiso othembekileyo we-biomarker.

Ukulungiswa kwedatha & AI

Ndikunye nenkqubela phambili ye-Hardware, isoftware kunye neendlela zohlalutyo lwedatha zivela ngokukhawuleza. Ukufunda umatshini (ml) kunye nobukrelekrele bobugcisa (i-AI) basetyenziselwa ukutolika idatha yedatha ye-MS ye-sks, ukuphucula imeko yokwamkelwa kwephecaphithi kunye nokunciphisa uhlalutyo ixesha lokuhlalutya. Ezi ndlela zinokufumana ngokuzenzekelayo i-peaks ebonakalayo, i-deconvolutick igqithisa imiqondiso, kwaye icombulule uhlalutyi ngokuchanekileyo, ukunciphisa impazamo yomntu. Umzekelo, i-algorithmsrithms ephambili inokuchonga ngokuzenzekelayo kwaye ilungelelanise i-Peask, ukulungiswa kwengxolo yesiseko kunye nokuhambisa iziphumo zokuchaneka okuphezulu. Ezo zinto zihamba nge-automandline yokulinganisa izixhobo zokusebenza kunye nokomeleza ukuzala, nto leyo ebaluleke kakhulu kwizifundo zeProtetic Protetic kunye nezifundo zeMetabomic.

Ukusetyenziswa kwe-mass spectrometry

I-Mass Spectrometry iqashwe kuluhlu olubanzi lwamabala, kubandakanya:

• Iproteomics kunye neMetabomics: KwiSayensi yoBomi, i-MS inceda ukuchongwa kunye nokudityaniswa kwamawakawaka kunye ne metaboltes kwiisampulu ezintsonkothileyo, i-Aicmark Recorting Accovery Apperlingy kunye nohlalutyo lweMetabol. Abaphandi banokubuqonda ngakumbi iimolekyuli zeselula zokuqonda iinkqubo zebhayoloji kunye neendlela zesifo.

• UQEQESHO LWEZOQOQOSHO NE-BIODODICINE:Kumayeza, i-MS isetyenziselwa ukubonisa i-bimarmars yezifo, yokufunda i-pharmaconkinetics yechiza, kunye nenkxaso kunyango oluchanekileyo. Umzekelo, iiprofayili okanye iiprofayili ze-metabolite kwigazi okanye izicubu zinokuhlaziywa ukuze zichongwe izifo kwangoko okanye zibeke esweni impendulo yonyango.

• Ukuhlolwa kwendalo kunye ne-forensics:I-MS ifumana ingcoliseko emoyeni, amanzi, kunye nomhlaba (njengezinyithi ezinzima, izitshabalalisi, kunye neziyobisi eziphilayo) kwaye ichonge ii-toxins iisampulu kunye neziyobisi kwiisampulu zendalo, ekuqinisekiseni ukhuseleko lwendalo, ukuqinisekisa ukhuseleko lwendalo. Umzekelo, ukuhlaziywa kwamanzi kwamanzi ngentsalela ye-pesticide okanye umoya kwizinto eziguqukayo zinokufezekiswa ngobuntununtunu obuphezulu.

• UKhuseleko loKutya kunye neSayensi yeZwensi:I-MS isetyenziselwa ukuvavanya ukungcola kunye nokongezwa kokutya kunye neziselo (E.G., iintsalela ze-pitiside, ezongeziweyo ezingekho mthethweni), ukuqinisekisa ukhuseleko lwemveliso. Ikwabalulekile kwiSayensi yeZandla kunye ne-Nanotechnology yokufakelwa kobume bekhemikhali kunye nolwakhiwo lwezixhobo ezintsha.

• Ukuhlolwa kwendawo kunye nohlalutyo lweseliIzixhobo ze-ms zihlalutya iisampulu zokubonisa i-Destters
  

  

Ukujonga kwixesha elizayo

Njengoko inkqubela phambili yetekhnoloji, i-New Innovations iyaqhubeka nokuvela kwi-spectrometry. Umzekelo, ukudityaniswa kwesampulu ye-microfluidic yesampulu ye-microfluidic, i-nooves e-Ion Anoengineineineineineineineineineineineineineineineineineineineineineineineineineineineines, kunye nohlalutyo lwedatha eqhutywa yi-AI-eqhutywa nge-AI-eqhutywa ngakumbi lubambisa imvakalelo kunye negalelo. Kwisishwankathelo, i-spectrometry iya kuqhubeka nokutyhala imida yesayensi, ivule amathuba amatsha kwiindawo ezifana nokubeka iliso kwindalo, isifo sonyango, kunye ne-chemistry obalulekileyo.
