A Readable Chromatic Biosensor with a Tunable Detection Threshold

Numerical Modeling of a Metamaterial Biosensor for Cancer Tissues Detection

In this paper, the numerical design and simulate a biosensor to detect tumors and cancerous tissues by using metamaterial structures in the microwave regime are presented. The presented structure consists of a microstrip transmission line and a split ring resonator (SRR) that form a bandpass filter and has a unique resonance frequency. Given that cancerous tissues have larger volumes of water t...

Hypergraphs with Zero Chromatic Threshold

Let F be an r-uniform hypergraph. The chromatic threshold of the family of F free, r-uniform hypergraphs is the infimum of all non-negative reals c such that the subfamily of F -free, r-uniform hypergraphs H with minimum degree at least c (|V (H)| r−1 ) has bounded chromatic number. The study of chromatic thresholds of various graphs has a long history, beginning with the early work of Erdős-Si...

Emergence of tunable resistive pulse sensing as a biosensor

DNA detection using a radio frequency biosensor with gold nanoparticles.

This study presents a novel method for DNA detection with multi-layer AuNPs to enhance overall detection sensitivity. This essay achieves not only an innovative radio-frequency biosensor but also a critical signal amplification methodology. Results show that bandwidth change for multi-layer AuNP with hybridization of DNA exceeds that for the double-layer AuNP up to 0.5 GHz. Furthermore, the dev...

A Digital Microfluidic Biosensor for Multianalyte Detection

A microfluidic lab-on-chip (LoC) for measuring the concentration of human body metabolites, using submicroliter droplets as reaction chambers, is presented in this paper. The device is based on the manipulation of droplets using the principle of electrowetting and is integrated with an optical absorbance measurement system for detection. We have demonstrated the detection of glucose using a col...
