Cell aggregation plays a key role in biofilm formation and pathogenesis of Staphylococcus species. Although the molecular basis of aggregation in Staphylococci has already been extensively investigated, the influence of environmental factors, such as

Capacitive biosensors are promising tools toward detection of bacterial cells. However, their sensitivity remains insufficient compared with more conventional techniques. To understand how to optimize it, we propose a complete and quantitative analys

This work describes the development of a characterization method for biofunctionalized surfaces and its use for biosensor applications. The method is based on the processing of fluorescence images obtained by confocal microscopy. It retrieves quantit

Adding vision capabilities to wireless sensors nodes (WSN) for the Internet-of-Things requires imagers working at ultra-low power (ULP) in nanometer CMOS systems-on-chip (SoCs). Such performance can be obtained with time-based digital pixel sensors (

Impedimetric biosensors with a passivation layer, also called capacitive biosensors, have recently shown great promise towards sensitive, selective and rapid detection of pathogen bacterial cells. However, few studies focus on their modeling, yet cri

Point-of-care (PoC) diagnostics for bacterial detection offer tremendous prospects for public health care improvement. However, such tools require the complex combination of the following performances: rapidity, selectivity, sensitivity, miniaturizat

To enable impedimetric sensing of whole-cell bacteria in a saline buffer with passivated microelectrodes, we designed a very high frequency (up to 575 MHz) complementary meta–oxide–semiconductor (CMOS) oscillator connected to on-chip ${\rm Al/Al}

Impedimetric sensors can be used for the detection of biological targets, such as bacteria. In this paper, 3D finite-element simulations show that random distributions of bacteria on interdigitated microelectrode sensor surfaces restrict their limit

Multiplexed, real-time and low cost detection of bioanalytes can be achieved by building integrated biosensor microarrays. The lack of design guidelines for this kind of biochip leads to inferior results com- pared to individual biosensors. In this p

We present the co-integration of CMOS-compatible Al/Al2O3 interdigitated microelectrodes (IDEs) with an electrokinetic-driven macroelectrode for sensitive detection of whole-cell bacteria in a microfluidic channel. Two frequency ranges applied to the
