We report on the utilization of triangular silver nanoprisms (AgTNPs) to create a highly responsive glucose biosensor. Glucose oxidase (GOD) was simply mixed with AgTNPs and cross-linked on the Pt electrode with chitosan (CHIT) medium by glutaraldehyde. Circular dichroism (CD) and UV-spectrum...
The opto-fluidic ring resonator (OFRR) is a sensitive label-free optical biosensor that is uniquely well suited for photonic and fluidic integration. For the first time we have explored the utility of this novel instrument for the analysis of methylation in oligonucleotides using the MBD-2...
A novel detection technique on biochip for the quantification of label-free C-reactive protein (CRP) based on molecular switching of fluorescence (MSF) is demonstrated by total internal reflection fluorescence microscopy. It alters fluorescence intensity of fluoreseinamine isomer 1 (FAI) upon...
A novel amperometric biosensor for nitromethane (CH 3 NO 2 ) based on immobilization of graphene (GR), chitosan (CS), hemoglobin (Hb) and room temperature ionic liquid (IL) on a glassy carbon electrode (GCE) was developed for the first time. The surface morphologies of a set of representative...
Nanomaterial modified electrode is useful for catalytic, analytical and biotechnological applications. Herein, a simple and sensitive method for the electrocatalytic detection of ascorbic acid (AA) using ultrathin Pd nanowire (NW) modified glassy carbon electrode is presented. Electrochemical...
Recent key developments in microbial fuel cell technology are reviewed. Fuel sources, electron transfer mechanisms, anode materials and enhanced O 2 reduction are discussed in detail. A summary of recently developed microbial fuel cell systems, including performance measurements, is conveniently...
Microbial screening is a primary concern for many products. Traditional techniques based on standard plate count (SPC) are accurate, but time consuming. Furthermore, they require a laboratory environment and qualified personnel. The impedance technique (IT) looking for changes in the electrical...
Screen-printed electrodes (SPE) have been widely used in the design of disposable sensors bringing advances in the use of electrochemical immunosensors for in field-clinical analysis. In this work, streptavidin polystyrene microspheres were incorporated to the electrode surface of SPEs in order...
Multivalent interaction between boronic acids immobilized on quartz crystal microbalance (QCM) sensor surface and the carbohydrates modified Au-nanoparticle (AuNP) has been demonstrated for the development of a sensitive carbohydrate biosensor. Briefly, a boronic acid-containing polymer...
