“…Sulfide ion (S 2– ) is widely used in industry and is also produced in biological systems. , However, S 2– is highly toxic and hazardous to human health, causing, for example, neurological damage, unconsciousness, and respiratory paralysis. , Meanwhile, the released S 2– can also readily convert into harmful H 2 S at physiological pH in the living system, causing conjunctivitis and other related eye diseases. , Thus, developing efficient sensors for the detection of S 2– is very meaningful and desired. In 2016, Lou et al reported a dual-signal-output (fluorescence and ion current signal) nanopore system based on cylindrical PET multi-nanopores modified with 6-aminouracil .…”

Bio-inspired polymeric nanochannel (also referred as nanopore)-based biosensors have attracted considerable attention on account of their controllable channel size and shape, multi-functional surface chemistry, unique ionic transport properties, and good robustness for applications. There are already very informative reviews on the latest developments in solid-state artificial nanochannel-based biosensors, however, which concentrated on the resistive-pulse sensing-based sensors for practical applications. The steady-state sensing-based nanochannel biosensors, in principle, have significant advantages over their counterparts in term of high sensitivity, fast response, target analytes with no size limit, and extensive suitable range. Furthermore, among the diverse materials, nanochannels based on polymeric materials perform outstandingly, due to flexible fabrication and wide application. This compressive Review summarizes the recent advances in bio-inspired polymeric nanochannels as sensing platforms for detection of important analytes in living organisms, to meet the high demand for high-performance biosensors for analysis of target analytes, and the potential for development of smart sensing devices. In the future, research efforts can be focused on transport mechanisms in the field of steady-state or resistive-pulse nanochannel-based sensors and on developing precisely size-controlled, robust, miniature and reusable, multi-functional, and high-throughput biosensors for practical applications. Future efforts should aim at a deeper understanding of the principles at the molecular level and incorporating these diverse pore architectures into homogeneous and defect-free multi-channel membrane systems. With the rapid advancement of nanoscience and biotechnology, we believe that many more achievements in nanochannel-based biosensors could be achieved in the near future, serving people in a better way.

“…1 For instance, the sulde (S 2À ) ion is highly toxic and harmful to human health and the ecological environment. [2][3][4] Usually, the S 2À ion is frequently distributed in natural water and wastewater samples because it is widely used in industrial processes (e.g. sulfur and sulfuric acid production, petroleum reneries, paper and pulp manufacturing, and sewage processing industries) and is also produced in biological systems (e.g.…”

“…In comparison with other technologies including gas chromatography, ion chromatography, titrimetry, colorimetry, and electrochemical method, uorescent sensors are particularly attractive because of high sensitivity, simple operation and rapid detection. 3,[11][12][13][14][15][16][17] Recently, uorescent sensors based on different uorescent probes have been widely reported for detection of cations. 18,19 However, only few researches focus on indirect detection of anions using uorescent off-on strategy.…”
