Summary: This paper introduces the first use of UHF RFID tags for wireless RF ice sensing applications, showing that the presence of ice as a superstrate on a planar ultra-thin dipole antenna can significantly lower the resonance frequency of the antenna and improve impedance matching. The RFID tags, with a range of 9.4 m, can detect ice formation up to 10 m away from the reader and monitor ice thawing with over 12 dB ice-sensitivity. The proposed sensing mechanism achieves 86% accuracy for tags positioned between 0.5 and 10.5 m with various obstructions, indicating that UHF RFID is a promising method for detecting ice formation in future smart cities.

Summary: Radio frequency identification (RFID) is an emerging wireless sensing technology that allows for multiple independent measurements or overcoming channel variations. This paper presents a dual-port/dual-integrated circuit (IC) RFID sensing tag based on a shared aperture dual-polarized microstrip antenna. The tag can be loaded with different sensors and demonstrates long read range and functionality as a battery-less wireless RFID light sensor.

Summary: This paper reviews the technological solutions for RFID sensing and discusses the benefits of using RFID sensors, such as the absence of batteries and lower cost. It categorizes RFID sensors into chipped and chipless configurations and analyzes their working mechanisms. While chip-equipped RFID sensing is mature and increasingly present in the market, chipless RFID sensing is a relatively new concept that requires further research for customization in specific scenarios.

Summary: Free copper ions have critical toxicity to cells, and it is important to develop sensitive monitoring methods. This study designed a ssDNA sequence for synthesizing silver nanoclusters and demonstrated that Cu+/Cu2+ can induce their aggregation and greatly enhance fluorescence emission. Based on this, a fluorescent sensing platform was developed for the detection of Cu+/Cu2+ in biological samples and intracellular imaging, with advantages of rapid detection, simplicity, high sensitivity, good cell permeability, and biocompatibility.

Summary: Silver deposition on oxygen plasma micro-nanostructured poly(methyl methacrylate) (PMMA) slides enhanced emitted fluorescence intensity, particularly for the detection of mycotoxins. The enhanced fluorescence signals achieved with these substrates were significantly higher than those obtained with flat PMMA slides. Additionally, the repeatability of the spots was high, while the stability of the slides was maintained for at least three months.

Summary: This work introduces a battery-less wireless respiration sensor based on MEMS technology, capable of measuring human respiration profiles from up to 2 meters away. The sensor is designed to be cost-effective, portable, and disposable, using resonance frequency modulation of a piezoelectric MEMS resonator to monitor respiration. A compensation method for motion-induced artifacts and drift is proposed and implemented for accurate tracking of patient's respiration profile over time.

Summary: Recently, there has been increased interest in electrochemiluminescent (ECL) immunosensors for biomarker detection. A highly enhanced ECL immunosensing platform was designed for ultrasensitive detection of carcinoembryonic antigen (CEA) using functional nanostructures. By entrapping CEA biomolecules using a sandwich approach and incorporating luminol/silver nanoparticles as the signaling probe, the immunosensor exhibited excellent sensitivity and selectivity for CEA detection. It also demonstrated good repeatability and stability in real human serum, making it a potential candidate for clinical CEA detection and monitoring.

Summary: Atomically precise silver nanoclusters (AgNCs) are nanostructures consisting of only a few silver atoms. When combined with cytosine-rich single-stranded oligonucleotides, they form DNA-templated silver nanoclusters (DNA-AgNCs) that exhibit highly luminescent and reproducible fluorescent properties. By utilizing nucleic acids as templates, AgNCs can be engineered to extend optical activity, allowing for the rational design of their properties, such as in biosensors for detecting heavy metals like Hg2+.
