Fluorescent probe encapsulated hydrogel microsphere for selective and reversible detection of Hg 2+

Super Hydrophilic Semi-IPN Fluorescent Poly(N-(2-hydroxyethyl)acrylamide) Hydrogel for Ultrafast, Selective, and Long-Term Effective Mercury(II) Detection in a Bacteria-Laden System

“…On the basis of linearly fitting the relation between I 425 /I 510 and Hg(II) ion concentration, the detection limit was calculated as 0.067 μM by the followed formula (eq 1) from the according method. 46 Compared to previous research 4,7,32,47,48 (Table S2), the detection limit of this fluorescent semi-IPN hydrogel is slightly higher, likely due to plenty of pre-existing water in the hydrogel, which plays a dilution role in the hydrogel.…”

Highly selective sensor for the detection of Hg 2+ ions using homocysteine functionalised quartz crystal microbalance with cross‐linked pyridinedicarboxylic acid

“…Some of the authors proposed a calorimetric approach for selective detection of mercury ions required laboratory‐based equipment for analysis [31, 32]. Fluorescent‐based sensors have been used by many researchers to detect the Hg 2+ ions selectively [33, 34] but this method required lab‐based equipment for analysis and detection. Also, most of the reported fluorescent probe reply only on the absorption and fluorescence change and need to the acquired dynamic procedure [35].…”

Highly selective piezoresistive sensor for mercury (Hg2+) ions detection using mercaptosuccinic acid-functionalized microcantilevers with cross-linked pyridinedicarboxylic acid

“…Some of the authors proposed a calorimetric approach for selective detection of mercury ions which required laboratory-based equipment for analysis (Borthakur et al, 2017;Zhang et al, 2016). Luminescence (fluorescent)-based sensors have been used by many researchers to selectively detect HMIs using Song et al (2017), Liu et al (2017a), Ma et al (2018), Rao et al (2018), Makwana et al (2016), Basu et al (2017), Lv et al (2015), Liu et al (2017bLiu et al ( , 2018, Xu et al (2019) and Shang et al (2019) but this method requires labbased equipment for analysis and detection. Also, most of the reported fluorescent probes rely only on the absorption and fluorescence change, hence the need to acquire effective procedure by Li et al (2019).…”
