“…The n value estimated was 1.898, indicating that two electron per molecule are involved in the oxidation of scopolamine. Hence, based on these results and according to others works for similar compounds [33][34][35] the proposed oxidation mechanism of scopolamine is shown in Scheme SM1.…”

“…Their work also demonstrates long time‐span stability over 7 days for the atropine sensors, which can be attributed to chitosan's excellent gel‐forming ability and nontoxicity. Similar research on chitosan‐nanocomposite based electrochemical sensors also demonstrated that chitosan nanocomposite materials can acquire addition chemo‐physical properties from different nanomaterials such as specificity to atropine from SWCNT‐chitosan and to dopamine from graphite‐chitosan composite . Together with nanomaterials, conductive polymer such as polypyrrole can also be added into chitosan nanocomposite for improved conductivity in such enzyme‐free sensors.…”

“…Mane et al. reported an atropine biosensor based on single walled carbon nanotube (SWCNT)‐chitosan film on glassy carbon electrode, in which chitosan was used as a dispersion matrix and stabilizer . Uniform dispersion of SWCNTs in chitosan is realized through covalent attachment, which is verified byFTIR and Raman spectra.…”

Recent years have witnessed ever expanding use of biosensors in the fields of environmental monitoring, homeland security, pharmaceutical, food and bioprocessing, and agricultural industries. To produce effective and reliable biosensors, good quality immobilization of biological recognition elements is critical. Chitosan and its nanocomposites emerge as an excellent immobilization matrix on biosensor surface. As a natural polysaccharide, chitosan has many useful characteristics, such as high permeability and mechanical strength, biocompatibility and non‐toxicity, availability, and low cost. Due to the presence of amino and hydroxyl groups on chitosan, chitosan can easily crosslink with a variety of nanomaterials. This investigation of chitosan nanocomposite‐based biosensors presents recent development and innovations in the preparation of chitosan nanocomposites in coordination with biosensors for various bio‐detection applications, including chitosan nanocomposites formed with carbon nanomaterials, various inorganic and biological complexes. These chitosan nanocomposite based biosensors have demonstrated good sensitivity selectivity and stability for the detection of different types of targets ranging from glucose, proteins, DNAs, small biomolecules to bacteria. It is in our hope that this review will offer guidance for the development of novel biosensors and open up opportunities in the field of biosensor research.

“…Compared with curve (a), in addition to the appearance of the oxidation peak of L-HSM (peak potential of 0.741 V), a new oxidation peak appears at 0.879 V. The potential difference (ΔE p ) between this peak and the L-HSM oxidation peak is 0.138 V. This peak is presumed to be the oxidation peak of D-HSM in ATP according to a previous report. 48 In addition, the oxidation peak of L-HSM in curve (b) is slightly higher than that of D-HSM, which is attributed to the incomplete racemization of L-HSM in ATP. On NIP/CuFeS 2 /C/GCE, both L-HSM (curve c) and ATP (curve d) show weak peak current densities, and both show only one oxidation peak for L-HSM.…”

In this work, an ant nest structured porous carbon nanosphere had been developed for the recognition detection of the atropine (ATP) enantiomers Dhyoscyamine (D-HSM) and L-hyoscyamine (L-HSM). Firstly, Fe-based organic framework was used as the substrate, and Cu ions and sulfur ions were separately introduced to obtain CuFeS 2 with ant nest structure by hydrothermal incubation. Then CuFeS 2 /C porous nanospheres (PNSs) were obtained by high-temperature calcination. The composite-modified electrode exhibited superior electrochemical performance for L-HSM due to the synergistic effect of CuFeS 2 cubic crystals and porous carbon, which has the high specific surface area of the ant nest structure. In addition, the molecularly imprinted polymer (MIP) about L-HSM formed with sulfonated-β-cyclodextrin (S-β-CD) and L-arginine (L-Arg) by cyclic voltammetry showed strong chiral recognition of D/L-HSM (ATP). Therefore, a novel electrochemical sensor was constructed based on CuFeS 2 /C PNSs and MIP to detect L-HSM by differential pulse voltammetry. Under the optimal conditions, the peak current density of L-HSM showed a good linearity in the concentration range of 0.02-4.6 μM with LOD and LOQ of 0.45 and 1.5 nM, respectively. The oxidation peaks of L-HSM and D-HSM were successfully identified from the racemic ATP, and the oxidation peak potential difference (ΔE p ) between them was 0.138 V. In conclusion, the sensor showed excellent reproducibility, repeatability, and stability and had been applied to the determination of L-HSM in human serum, saliva, and ATP sulfate tablets with satisfactory results.
