“…Tamersit et al [32] has recently reported a FET-based DNA sensor incorporating carbon nanotube and vacuum gate dielectric whose operation is based on dielectric and charge modulation. Lee et al [33] reported a FET incorporating single-walled carbon nanotube for electrochemical sensing of filamentous M13 phage. Carbon-based coatings, including carbon nanotube, have promising results in reducing failure rates and enhancing biocompatibility in biomedical implants due to their exceptional properties and specific coating techniques [31].…”

This paper critically investigates the effect of doping on different device characteristics of a Ge/Si interfaced nanowire MOSFET (GSI-NWM) for analog performance enhancement. The doping of source, channel, and drain has a prominent effect on important device characteristics, which has been investigated through DC and AC analysis performed on the SILVACO TCAD simulator. A numerical computational-based simulation study has been used to investigate the modulation of various device characteristics, such as threshold voltage, cut-off frequency, subthreshold swing, MTPG, current ratio, channel resistance, and transconductance. The investigation revealed a strong dependence of most of these characteristics on the source, channel, and drain doping levels, providing valuable insights into device performance. Proper optimization in doping can significantly improve the performance of the device. A compact physics-based analytical model has been mathematically evaluated and proposed in this work, showing an excellent in-line agreement with the simulated results. This is a novel approach for improving the analog performance parameters of a nanowire MOSFET through doping optimization, which incorporates gate oxide stacking and germanium as a source material. In this work, the biosensing capability of the GSI-NWM has also been discussed and evaluated.

Among the methods for onsite detection of specific biomolecules, the use of retroreflective Janus particles (RJPs) is a simple and efficient method for biophotonic probes to detect biotarget molecules with spatioselectivity, which can make the RJPs align toward light sources after capturing the target biomolecules, enhancing retroreflection. Because RJP has two distinct regions with different properties, specific reagents can be easily functionalized through chemical reactions between the functional groups and biotarget molecules. The number of functional groups on RJP will be the critical parameter for efficiency of sensing ability. Here, we introduce clickable (azide) polymer brush on surface of RJP via different surface polymerization methods (grafting to and grafting from method). Azide groups allow for the easy modification of dibenzocyclooctyne‐linked biomolecules onto silica particles through click chemistry. We prepare RJPs with different quantities of azide functional groups on their surfaces via solvent volatilization method and metal deposition. Using a retroreflective immunosensing system, we perform sensitive detection of target biomolecules.This article is protected by copyright. All rights reserved
