O nou\u0103 tehnologie revolu\u021bionar\u0103, cunoscut\u0103 sub numele de \u201ePlasmoSniff\u201d, promite s\u0103 schimbe modul \u00een care se efectueaz\u0103 diagnosticul bolilor pulmonare. Acest sistem inovator utilizeaz\u0103 un senzor portabil capabil s\u0103 identifice biomarkerii bolii \u00een aerul expirat de pacient. Cercet\u0103torii sugereaz\u0103 c\u0103 tehnologia ar putea fi utilizat\u0103 at\u00e2t \u00een cabinetele medicale, c\u00e2t \u0219i la domiciliu, oferind astfel o solu\u021bie accesibil\u0103 \u0219i eficient\u0103 pentru pacien\u021bi.<\/p>\n

Detalii despre acest dispozitiv au fost publicate recent \u00een revista de specialitate Nano Letters.<\/p>\n

Cum func\u021bioneaz\u0103 testul<\/h2>\n

Procedura este simpl\u0103 \u0219i similar\u0103 cu utilizarea unui inhalator pentru astm. Pacientul inhaleaz\u0103 nanoparticule special concepute, care transport\u0103 biomarkeri sintetici. Aceste mici \u201eetichete\u201d chimice reac\u021bioneaz\u0103 \u00een prezen\u021ba infec\u021biilor pulmonare. \u00cen cazul \u00een care pl\u0103m\u00e2nii sunt s\u0103n\u0103to\u0219i, nanoparticulele sunt eliminate f\u0103r\u0103 modific\u0103ri. \u00cen schimb, \u00een prezen\u021ba pneumoniei, enzimele produse de infec\u021bie separ\u0103 biomarkerii de particule, iar ace\u0219tia sunt elimina\u021bi prin respira\u021bie, devenind astfel detectabili de senzor.<\/p>\n

\u201e\u00cen practic\u0103, un pacient ar inhala nanoparticulele \u0219i, \u00een decurs de aproximativ 10 minute, ar expira un biomarker care reflect\u0103 starea pl\u0103m\u00e2nilor. Tehnologia PlasmoSniff poate identifica ace\u0219ti biomarkeri \u00een c\u00e2teva minute, direct la punctul de \u00eengrijire\u201d, a explicat Aditya Garg, cercet\u0103tor postdoctoral implicat \u00een acest proiect.<\/p>\n

Detectarea semnalelor extrem de slabe<\/h2>\n

Senzorul PlasmoSniff se bazeaz\u0103 pe principiile plasmonicii, un domeniu care studiaz\u0103 interac\u021biunea luminii cu materia la scar\u0103 nanometric\u0103. Dispozitivul con\u021bine o pelicul\u0103 sub\u021bire de aur, \u00eempreun\u0103 cu nanoparticule de aur, separate de un interval de doar cinci nanometri, unde moleculele \u021bint\u0103 sunt capturate.<\/p>\n

Moleculele de ap\u0103 de pe suprafa\u021ba senzorului ajut\u0103 la \u201eprinderea\u201d biomarkerilor, iar ace\u0219tia sunt ulterior analiza\u021bi prin spectroscopie Raman, o tehnic\u0103 care permite identificarea moleculelor dup\u0103 \u201eamprenta\u201d lor vibra\u021bional\u0103. \u201eEste o problem\u0103 de tip \u2018acul \u00een carul cu f\u00e2n\u2019, dar metoda noastr\u0103 reu\u0219e\u0219te s\u0103 detecteze molecule care, altfel, ar fi ascunse printre mii de altele\u201d, a declarat Loza Tadesse, coordonatoarea cercet\u0103rii.<\/p>\n

Rezultate promi\u021b\u0103toare \u0219i aplica\u021bii extinse<\/h2>\n

Tehnologia a fost deja testat\u0103 pe probe de lichid pulmonar de la \u0219oareci, care au fost expu\u0219i la biomarkeri ai pneumoniei. Senzorul a reu\u0219it s\u0103 identifice aceste semnale la concentra\u021bii extrem de reduse, similare celor \u00eent\u00e2lnite \u00een infec\u021bii reale.<\/p>\n

Cercet\u0103torii se concentreaz\u0103 \u00een prezent pe integrarea sistemului \u00eentr-un dispozitiv portabil, care ar putea include o masc\u0103 pentru colectarea respira\u021biei \u0219i un detector compact. De asemenea, tehnologia PlasmoSniff ar putea fi adaptat\u0103 pentru a depista alte afec\u021biuni, inclusiv diverse tipuri de cancer \u0219i infec\u021bii virale, dar \u0219i pentru monitorizarea poluan\u021bilor din aer.<\/p>\n

\u201ePlatforma noastr\u0103 nu este limitat\u0103 doar la diagnosticarea medical\u0103. Dac\u0103 o molecul\u0103 are o amprent\u0103 vibra\u021bional\u0103 cunoscut\u0103 \u0219i poate interac\u021biona cu apa, sistemul nostru o poate detecta\u201d, a ad\u0103ugat Tadesse.<\/p>\n

Dac\u0103 va fi implementat\u0103 pe scar\u0103 larg\u0103, tehnologia PlasmoSniff ar putea transforma diagnosticul bolilor pulmonare, f\u0103c\u00e2ndu-l mai rapid, mai accesibil \u0219i mai eficient la nivel global.<\/p>\n","protected":false},"excerpt":{"rendered":"
