“…Furthermore, the C-dots-CPE possesses higher stability and has a short response time, which is comparable to the response time of AgNp-CPE. The prolonged lifetime of the electrode in case of AgNp when compared to the Bare-CPE is mainly a function of its antibacterial and antifouling properties [44]. Surprisingly, the lifetime of the C-dots-CPE was even longer than that of the AgNp-CBE, which indicates that the included C-dots also have interesting antifouling properties, as recently observed by several other works [45,46].…”

Two inexpensive and simple methods for synthesis of carbon nanodots were applied and compared to each other, namely a hydrothermal and microwave-assisted method. The synthesized carbon nanodots were characterized using transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis), photoluminescence (PL), Fourier transform-infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The synthesized microwave carbon nanodots had smaller particle size and were thus chosen for better electrochemical performance. Therefore, they were used for our modification process. The proposed electrodes performance characteristics were evaluated according to the IUPAC guidelines, showing linear response in the concentration range 10−6–10−2, 10−7–10−2, and 10−8–10−2 M of tobramycin with a Nernstian slope of 52.60, 58.34, and 57.32 mV/decade for the bare, silver nanoparticle and carbon nanodots modified carbon paste electrodes, respectively. This developed potentiometric method was used for quantification of tobramycin in its co-formulated dosage form and spiked human plasma with good recovery percentages and without interference of the co-formulated drug loteprednol etabonate and excipients.

“…Inspired by mussel chemistry, polydopamine (PDA) can be formed by self‐polymerization of dopamine under weak alkaline aqueous conditions and an oxygenic environment at room temperature 16,22–24 . More importantly, PDA containing ample catechol and amine groups can be regarded as a reducing and stabilizing agent to produce AgNPs 9,25 . In addition, PDA has a diverse number of functions such as metal ion chelation activity, free radical scavenging ability and antioxidant activity 15,22,26–29 .…”

Silver nanoparticles (AgNPs) were synthesized by a facile, mild and green method using dopamine as a reducing and stabilizing agent and were introduced to waterborne polyurethane (WPU) via an in situ emulsification method to prepare antibacterial nanocomposite films. The formation of AgNPs was characterized by UV–visible spectroscopy and XRD. The dispersion of AgNPs was confirmed by TEM and the thermal stability of WPU/Ag nanocomposites was confirmed by TGA. The results showed that AgNPs were uniformly dispersed in the WPU matrix. The introduction of AgNPs significantly improved the thermal stability of WPU films. With incorporation of 0.1 wt% AgNPs, a five‐fold increase in the tensile strength was achieved without sacrificing the ultimate strain. The WPU/Ag nanocomposite films showed antibacterial activity against Escherichia coli and Staphylococcus aureus. © 2021 Society of Industrial Chemistry.

“…Even though potentiometric sensors are the top candidate for LTCM, the main limitation is that the sensing scope is only applicable to ions. Also, the morphology change of the sensor ISM matrix (e.g., aqueous layer formation inside the ISM matrix, 126 physical damage by the debris and particles attached, 127 biofouling, 128 and ISM component leaching 129 ) deteriorates ion affinity and ion diffusion in the ISM matrix and causes measurement errors, and finally declines the long-term accuracy of sensors. Furthermore, because contaminant concentrations are quantified using the Nernst equation ( ), the signal readings of potentiometric sensors are temperature-dependent, and logarithmic response can result in drastic reading drift.…”

Long-term continuous monitoring (LTCM) of water quality can bring far-reaching influences on water ecosystems by providing spatiotemporal data sets of diverse parameters and enabling operation of water and wastewater treatment processes in an energy-saving and cost-effective manner. However, current water monitoring technologies are deficient for long-term accuracy in data collection and processing capability. Inadequate LTCM data impedes water quality assessment and hinders the stakeholders and decision makers from foreseeing emerging problems and executing efficient control methodologies. To tackle this challenge, this review provides a forward-looking roadmap highlighting vital innovations toward LTCM, and elaborates on the impacts of LTCM through a three-hierarchy perspective: data, parameters, and systems. First, we demonstrate the critical needs and challenges of LTCM in natural resource water, drinking water, and wastewater systems, and differentiate LTCM from existing short-term and discrete monitoring techniques. We then elucidate three steps to achieve LTCM in water systems, consisting of data acquisition (water sensors), data processing (machine learning algorithms), and data application (with modeling and process control as two examples). Finally, we explore future opportunities of LTCM in four key domains, water, energy, sensing, and data, and underscore strategies to transfer scientific discoveries to general end-users.
