MİKRO-AKIŞKANLAR-DİNAMİĞİ VE ÇİP-ÜSTÜ-LABORATUVAR ARAŞTIRMA GRUBU
ETKİNLİKLER:
1970'lerden bu yana elektronik bileşenlerin minyatürleştirme eğilimi ve 1980'lerden bu yana mikro ve nano ölçekli cihazlar için gelişmiş üretim tekniklerinin geliştirilmesi birçok alanda mikrometre ve nanometre boyutlarına sahip cihazların kullanılmasına yol açtı. Sonuç olarak, mikro ölçekte akışkan akış olaylarıyla ilgilenen bir mikroakışkan alanı ilginç ve zengin bir araştırma alanı haline geldi. Mikro-akışkan sistemlerinin tasarım ve proses kontrolü için mikro ölçekte akışkan, termal ve kütle taşınımının temel olarak anlaşılması çok önemlidir.
Lab-on-a-chip (LOC) cihazları, karmaşık kimyasal yönetim ve analiz sistemlerini sadece milimetre veya santimetre boyutunda bir çip üzerine entegre edebilen ve elektronik ve optik algılama sistemleriyle etkileşime girebilen mikroakışkan platformlardır. LOC teknolojisinin nihai amacı, aynı analitik görevleri oda boyutunda veya tezgah boyutunda meslektaşları gibi hızlı ve doğru bir şekilde gerçekleştirebilen, ancak çok daha düşük üretim ve işletme maliyetlerinde ve daha da önemlisi -situ test ve algılama. Bu tür cihazlar, yaşam bilimleri, uzay araştırmaları, savunma sanayii, atmosfer bilimleri, ilaç araştırmaları vb. Tarafından talep edilmektedir.
Bilkent Üniversitesi Mikroakışkanlar ve Çip Üzerine Laboratuar Araştırma Grubu (BU-MLRG) 'nin ilgi alanı mikrokanal ağlarında nakliye olayları ve biyomedikal, biyolojik ve kimyasal uygulamalar için LOC teknolojisinin geliştirilmesi ile ilgili temel ve deneysel araştırmalara dayanıyor.
