A novel graphene-based glucose sensor-design is formulated and explored in silico. An ad hoc host molecule is tailored to bind to glucose by multiple hydrogen bonds. A pyridinic core is chosen for this receptor in order to allow for “socket-plug” dative bonding to boron sites of boron doped graphene. The modeling employs DFT (Density Functional Theory) together with an effective aqueous environment...
Carbon nanotubes (CNTs) were chemically modified to achieve strong binding strength with the attached functional components as well as good dispersability and nanoparticle size-uniformity. An efficient multi-oxidation process was developed to create porous out layer with many nanoscale defects on the surface of CNTs for metallic nanoparticle close attachment and bond sufficient oxygen-containing groups,...
This paper presents a novel process to encapsulate nanochannels with a very high length/height aspect ratio (750 µm/300 nm) for nanofluidic devices. We use low temperature lamination of dry film resist (DFR) to encapsulate wet etched nanochannels with water inside. With this method stiction can be prevented as no drying steps are used. In addition, the presence of water inside the nanochannels makes...
Current paper describes the testing, alignment and bonding of a PDMS-glass bonded microfluidic device used for single cell analysis. The channels were successfully tested using carboxylate modified polystyrene beads for any leakage. Polystyrene beads of 2 mum have been successfully trapped within the reservoir of the device by well known dielectrophoresis technique and the same technique will be used...
