“…The biosensor could identify IgG at concentrations as low as 2.0 × 10 −5 ng/mL and up to 10 3 ng/mL. The authors claim that their reported biosensors show a broader detection range and lower LOD than those previously reported [56] , making it a more promising potential for wastewater applications.…”

“…Because IgG antibodies are expensive and difficult to prepare, molecularly imprinted polymers are perfect substitutes. Bai et al manufactured molecularly imprinted polymers on top of nano Au/nano Ni modified Au electrodes through metal free visible light induced atom transfer radical polymerization (MVL ATRP) [56] . During fabrication, IgGs were conjugated with fluorescein isothiocyanate as a template and photocatalyst.…”

Reversible deactivation radical polymerization (RDRP) is a class of powerful techniques capable of synthesizing polymers with a well‐defined structure, properties, and functionalities. Among the available RDRPs, ATRP is the most investigated. However, the necessity of a metal catalyst represents a drawback and limits its use for some applications. O‐ATRP emerged as an alternative to traditional ATRP that uses organic compounds that catalyze polymerization under light irradiation instead of metal. The friendly nature and the robustness of O‐ATRP allow its use in the synthesis of tailorable advanced materials with unique properties. In this review, the fundamental aspects of the reductive and oxidative quenching mechanism of O‐ATRP are provided, as well as insights into each component and its role in the reaction. Besides, the breakthrough recent studies that applied O‐ATRP for the synthesis of functional materials are presented, which illustrate the significant potential and impact of this technique across diverse fields.

The accumulation of metal ions in the body is caused by human activities and industrial uses. Among these metal ions, copper is the third most abundant ion found in the human body and is indispensable for health because it works as a catalyst in the iron absorption processes. However, high doses of copper ions have been reported to generate various diseases. Different types of sensors are used to detect metal ions for several applications. To design selective and specific recognition sites on the sensor surfaces, molecular imprinting is one of the most used alteration methods to detect targets by mimicking natural recognition molecules. In this study, an ion-imprinted polymer-integrated plasmonic sensor was prepared to selectively detect copper (Cu(II)) ions in real-time. Following different characterization experiments, the Cu(II)-imprinted plasmonic sensor was employed for kinetic, selectivity, and reusability studies. According to the results, it was observed that this sensor can measure with 96% accuracy in the Cu(II) concentration range of 0.04–5 μM in buffer solution. The limit of detection and limit of quantification values were computed as 0.027 µM and 0.089 µM. The results also showed that this plasmonic sensor works successfully not only in a buffer solution but also in complex media such as plasma and urine.
