Nanodiamond Based Composite Structures For Biosensing Applications, Pedro Javier Villalba May 2014

Nanodiamond Based Composite Structures For Biosensing Applications, Pedro Javier Villalba

Graduate Theses and Dissertations

This dissertation presents the synthesis and application of nanodiamond based materials for electrochemical biosensors. In this research work, nanodiamond particles have been used to prepare doped and undoped nanocrystalline diamond films, and conducting polymer composites for enhanced biosensing. The performance of the synthetized materials towards sensing applications was evaluated against glucose amperometric biosensing. Besides, cholesterol biosensing was attempted to prove the capabilities of the platform as a generic biosensing substrate.

Biosensors have been proved to provide reliable detection and quantification of biological compounds. The detection of biological markers plays a key factor in the diagnosis of many diseases and, even ...


Hierarchically Ordered Montmorillonite Block Copolymer Brushes, Ross Eric Behling Jan 2010

Hierarchically Ordered Montmorillonite Block Copolymer Brushes, Ross Eric Behling

Graduate Theses and Dissertations

We report the phase behavior of a new class of polymer

nanocomposites, montmorillonite (MMT) block copolymer brushes

(MBBs). MBBs are comprised of discrete MMT particles encapsulated with block copolymer brushes synthesized via surface initiated atom transfer radical polymerization. Polystyrene-b-poly(n-butyl acrylate) MBBs of varying composition and total Mn = 80--250 kDa were compared with bulk block copolymers via electron

microscopy and a host of mechanical tests. MBBs were found to self

assemble into single grain morphologies across incredibly large

areas (> 3 um). Perhaps most promising is that MBBs maintain

similar melt state properties to bulk block copolymers and are thus

amenable ...
