Amplification-free DNA Sensor for the One-Step Detection of the Hepatitis B Virus Using an Automated Paper-Based Lateral Flow Electrochemical Device

Chawin Srisomwat et al.

Summary: An automated paper-based eLFA device was developed for quantitative detection of hepatitis B virus (HBV) using a time-delayed microfluidic strategy and gold metallization for signal-on electrochemical detection of target DNA. The use of pyrrolidinyl peptide nucleic acid as a probe provided higher specificity and lower background currents, achieving a broad dynamic range and excellent detection limit. The device simplifies the operation for HBV DNA detection without the need for amplification steps, while producing results consistent with standard real-time PCR.

Wearable Analytical Platform with Enzyme-Modulated Dynamic Range for the Simultaneous Colorimetric Detection of Sweat Volume and Sweat Biomarkers

Andreu Vaquer et al.

Summary: The manuscript presents a wearable analytical platform that can measure sweat lactate concentration and sample volume simultaneously. The lactate biosensor features a signal modulation mechanism and competitive enzyme inhibitor for precise measurements, while a volume sensor with gold nanoparticles allows estimation of sweat volume. This platform enables quantification of sweat lactate levels independently of sweat rate, making it suitable for developing disposable wearable biosensors.

Regulating Valence States of Gold Nanocluster as a New Strategy for the Ultrasensitive Electrochemiluminescence Detection of Kanamycin

Zhongnan Huang et al.

Summary: This study presents a facile and highly efficient electrochemiluminescence (ECL) strategy for kanamycin detection based on gold nanocluster probes, utilizing the valence state effect of the gold nanoclusters. By inducing a valence state change in the chemically reduced gold nanoclusters, the detection of kanamycin with excellent sensitivity and extremely low detection limit was achieved without the need for signal amplification or aptamers. The proposed sensing platform showed high selectivity, an extremely broad linear range, and excellent recoveries for kanamycin detection in milk samples.

Plasmonic Detection of Mercury via Amalgamation on Gold Nanorods Coated with PEG-Thiol

John R. Crockett et al.

Summary: This study presents a strategy for plasmonic detection of mercury using PEG@AuNRs, which demonstrate superior advantages including sensitivity, stability, and specificity compared to traditionally coated AuNRs. Manipulating the plasmonic responses of PEG@AuNRs towards Hg can be achieved by adjusting the AuNR concentration and incubation time, contributing to the design of a smart Hg2+-sensing platform with an adjustable peak plasmonic response region.

Functionalized Gold Nanoparticles as an Active Layer for Mercury Vapor Detection at Room Temperature

Ilaria Fratoddi et al.

Summary: In recent years, nanomaterials such as gold nanoparticles have been used as solid-state sensors to detect poisonous elements in the environment. Chemoresistive sensors based on gold nanoparticles functionalized with mixed thiol ligands show selective and reproducible sensing behavior towards Hg-vap(0) in the range of 0.1-1.0 ng/mL, with irreversible interaction mechanisms observed in isolated AuNPs samples. Interconnected AuNPs exhibit reversible behavior after exposure to Hg-vap(0), indicating the potential for future use in real-time outdoor air quality monitoring as nanodevices.
