C 2012 American Chemical Society Graphene: The Game Changer? I t has only been eight years since the isolation of graphene 1 and over a year since the 2010 Nobel Prize in Physics was jointly awarded to Andre Geim and Konstantin Novoselov “for groundbreaking experiments regarding the two-dimensional material graphene.” Nevertheless, the number of graphene publications is still rapidly growing. T...

Biosensors based on nanotechnology are developing rapidly and widely applied in many fields including biomedicine, environmental monitoring, national defense analytical chemistry, have achieved vital positions these fields. Novel nano-materials intensively developed manufactured for potential biosensing theranostic applications while lacking comprehensive assessment of their health risks. The i...

Neuromolecular Imaging (NMI) based on adsorptive electrochemistry, combined with Dual Laser Doppler Flowmetry (LDF) is presented herein to investigate the brain neurochemistry affected by enoxaparin (Lovenox(®)), an antiplatelet/antithrombotic medication for stroke victims. NMI with miniature biosensors enables neurotransmitter and neuropeptide (NT) imaging; each NT is imaged with a response ti...

Nanostructured materials with feature sizes in tens of nanometers have enhanced the performance of several technologies, including fuel cells, biosensors, biomedical device coatings, and drug delivery tools. Nanoporous gold (np-Au), produced by a nano-scale self-assembly process, is a relatively new material that exhibits large effective surface area, high electrical conductivity, and catalytic...

Tailoring conducting polymers (CPs) such as polyaniline (PANI) to deliver the appropriate morphology, electrochemical properties and processability is essential for development of effective polymer-based sensors biosensors. Composite PANI electrodes detection ammonium (NH4+) have been previously reported, but limited by their reliance on electrocatalytic reaction between NH4+ a metal/nano-catal...
