Low‐Frequency Noise and Stability in Electrolyte‐Gated Nanoscale Silicon Field‐Effect Transistor Sensors

Small Methods, EarlyView.
Electrolyte‐gated nanoscale silicon field‐effect transistor sensors provide exceptional charge sensitivity and direct electrical readout. However, their sensing accuracy is fundamentally limited by low‐frequency noise and baseline drift. This review examines the origins of noise and drift in these sensors, summarizes the key mitigation strategies, and ...

Strategies for enhancing sensitivity in lateral flow assays

VIEW, EarlyView.
Lateral flow assays (LFAs) are essential for cost‐effective, rapid point‐of‐care diagnostics. However, conventional colourimetric LFAs often lack the sensitivity required for low‐abundance biomarkers. This review evaluates six enhancement strategies: flow modulation, sample preconcentration, advanced reporters, chemical signal amplification, structural

Electrochemical aptasensors for ultrasensitive multiplexed detection: Towards a new era of precision diagnostics and environmental monitoring

VIEW, EarlyView.
Electrochemical aptasensors are emerging as powerful platforms for precision diagnostics and environmental monitoring, owing to their high selectivity, programmability and compatibility with miniaturised systems. However, their broader application is constrained by limited signal intensity and challenges in reliable multiplexed detection.

A comparative analysis of cell death signalling in RNA and DNA virus infections and potential inhibitory strategies

The FEBS Journal, EarlyView.
RNA and DNA viruses can manipulate host cell death through various mechanisms. RNA viruses (H1N1, SARS‐CoV‐2) induce acute apoptosis, necroptosis, and pyroptosis to promote rapid viral transmission and epithelial barrier damage. In contrast, DNA viruses (HSV‐1, EBV) regulate these mechanisms to sustain a lytic‐latency cycle, evade immune response and ...
