the efficient detection of charged biomolecules by biosensor with appropriate semiconducting nanomaterials and with optimum device geometry has caught tremendous research interest in the present decade. here, the performance of various label-free electronic biosensors to detect bio-molecules is investigated by simulation technique. silicon nanowire sensor, nanosphere sensor and double gate fiel...

In this paper a novel elctrochemical HbA1c biosensor based on flow injection and screen-printed electrode was developed. The reticulated vitreous carbon (RVC) electrode was modified with 3aminophenylboronic acid, chitosan (CS), and tetraenthoxyl silica (TEOS), which entrapped carbon nanotubes to form a sol-gel film at the surface of the screen-printed electrode. The electrochemical behavior of ...

A monolithically integrated micro-fluidic biosensor system-on-chip (μBio-SSoC) is first realized in standard CMOS processes. This μBio-SSoC is composed of a CMOS-based microfluidic pump, a polysilicon nanowire (SiNW) biosensor, and driving circuits. With 1.5V driving voltage, the microfluidic pump drives sample-liquids to biosensing area with 34 μm/s flowing velocity. After pumping, the detecti...

This work is about gas biosensing with a cytochrome c biosensor. Emphasis is put on the analysis of the sensing process and a mathematical model to make predictions about the biosensor response. Reliable predictions about biosensor responses can provide valuable information and facilitate biosensor development, particularly at an early development stage. The sensing process comprises several in...

A quartz crystal microbalance (QCM) biosensor based on polydopamine (PDA) surface was developed for real-time analysis of the binding kinetics of protein-protein interactions. The biosensor was fabricated by simply immersing the gold sensor chip into an aqueous dopamine solution at pH 8.5 leading to a spontaneous deposition of PDA film onto the sensor chip surface, which was followed by incubat...

To achieve a reliable formation of a surface-enhanced Raman scattering (SERS) sensor with evenly distributed hot spots on a wafer scale substrate, we propose a hybrid approach combining physical nanolithography for preparing Au nanodisks and chemical Au reduction for growing them. During the chemical growth, the interstitial distance between the nanodisks decreased from 60 nm to sub-5 nm. The r...
