Ülevaade
Uurimisrühma visiooniks on: “Innovation thorough the border crossing”. Uurimistöö teostamiselsaavad kokku erinevate instituutide, ülikoolide ja erasektori spetsialistid, selleks et teaduslikud avastused muuta reaalseteks toodeteks. Viimase 15 aasta jooksul on rühma teadlased arendanud erinevaid analüsaatoreid (TRL 6-7) paljudele erinevatele partneritele (näit. Eesti Politsei ja Piirivalveamet). Uurimisühma tuumiktehnoloogiad on kapillaarelektroforees, fluorestsents, juhtivus, gaaskromatograafia, mikrofluidika ning teised instrumentaal ja analüütilised tehnoloogiad. Tehakse koostööd erinevate töögruppidega üle maailma ning pakutakse oma kompetentsi erinevates partnerlustes (näit Horizon Europe jt).
Tähtsamad tulemused
2022. aastal: (1) Viidi läbi portatiivse narkoanalüsaatori Drug Hunter (www.drughunter.eu ) põhjalik testimine ja funktsionaalsuse parandamine. Drug Hunterit testiti koostöös Eesti politseiga narkoreididel; (2) Arendati, testiti ja valideeriti tehisintellektil põhinevat ekspertsüsteeminarkoanalüsaatoris Drug Hunter, et parandada elektroforeetiliste mustrite tuvastamist, vähendades seeläbi vigu ja kasutajalt nõutavat kompetentsi tulemuste tõlgendamiseks; (3) Esimene portatiivne GHB meetri prototüüp on testimisel.
