“…At the same time, a new peak at 283.6 eV in the C 1s spectra suggests the formation of binding interaction between Al 3+ and TBAPy . In addition, the characteristic binding energy of O 1s shows a significant shift, indicating the efficient energy transfer between TBAPy and Al 3+ . Subsequently, the UV–visible absorption spectrum of Ni‐MOG after Al 3+ detection was blue‐shifted compared the original one (Figure S7), which also indicates that there is a certain interaction between Ni‐MOG and Al 3+ .…”

As an important metal element, aluminium has a significant impact on the environment and human health, and thus the detection of Al 3+ has become the subject of much research. We synthesized a Ni(II)-based metal-organic gel (Ni-MOG), which can serve as an Al 3+ fluorescence sensor with high selectivity and sensitivity, the limit of detection being calculated to be 0.5 μM. In addition, a composite film was further fabricated by hybridization of this Ni-MOG with poly(vinyl alcohol). The composite film produced a rapid fluorescence response to Al 3+ solutions at concentrations above 5 × 10 −5 M in 5 min. The Ni-MOG composite film can also be successfully applied for the sensitive detection of Al 3+ in real samples of tap water and seawater. The effective detection of Al 3+ described in this contribution provides a new insight into water quality monitoring and has promising application value.

“…Nanotechnology involves creation and manipulation of materials at the nanoscale by altering their molecular structure (Rajasekharreddy & Rani, 2014). Different metals such as silver, gold, iron, titanium, zinc, magnesium and copper have been subjected to nanoformulation for a wide range of beneficial applications by adopting various physical, chemical and biological techniques (Ponarulselvam et al, 2012; Painuli, Joshi & Kumar, 2018). Green synthesis is an alternative approach for synthesizing nanoparticles (NPs) using natural resources such as microorganisms and medicinal plants as reducing agents.…”

BackgroundGreen synthesis of metallic nanoparticles has gained significant attention in the field of nanomedicine as an environment-friendly and cost-effective alternative in comparison with other physical and chemical methods. Several metals such as silver, gold, iron, titanium, zinc, magnesium and copper have been subjected to nanoformulation for a wide range of useful applications. Silver nanoparticles (AgNPs) are playing a major role in the field of nanomedicine and nanotechnology. They are widely used in diagnostics, therapeutic and pharmaceutical industries. Studies have shown potential inhibitory antimicrobial, anti-inflammatory and antiangiogenesis activities of AgNPs.MethodsAgNPs have been synthesized using silver nitrate and methanolic root extract of Rhazya stricta that belongs to the Apocynaceae family. Stability and dispersion of nanoparticles were improved by adding xylitol. Synthesized nanoparticles were characterized by UV–Vis spectroscopy, scanning electron microscopy, energy dispersive spectroscopy, X-ray diffractometer and Fourier transforms infrared spectroscopy. Furthermore, the antibacterial effect of the plant extract and the nanoparticles were evaluated against gram-positive (Bacillus subtilis) and gram-negative (Escherichia coli) bacteria.ResultsThe average size of AgNPs synthesized, was 20 nm with the spherical shape. Rhazya stricta based nanoparticles exhibited improved antibacterial activity against both gram-positive and negative strains.

“…The sensor devised using Syzygium cumini (Jamun) for the reduction of silver ions is purposefully used for the detection of aluminum metal. The Jamun leaf extract was irradiated with sunlight and acted as a capping and stabilizing agent for the above-mentioned process with a low detection limit of 0.01 ppm . A new and innovative fluorescent l -tyrosine feathered Ag NPs sensor is applied for the simultaneous detection of copper and cobalt ions.…”

Silver nanoparticles developed via biosynthesis are the most fascinating nanosized particles and encompassed with excellent physicochemical properties. The bioinspired nanoparticles with different shapes and sizes have attracted huge attention due to their stability, low cost, environmental friendliness, and use of less hazardous chemicals. This is an ideal method for synthesizing a range of nanosized metal particles from plants and biomolecules. Optical biosensors are progressively being fabricated for the attainment of sustainability by using opportunities offered by nanotechnology. This review focuses mainly on tuning the optical properties of the metal nanoparticles for optical sensing to explore the importance and applications of bioinspired silver nanoparticles. Further, this review deliberates the role of bioinspired silver nanoparticles (Ag NPs) in biomedical, agricultural, environmental, and energy applications. Profound insight into the antimicrobial properties of these nanoparticles is also appreciated. Tailor-made bioinspired nanoparticles with effectuating characteristics can unsurprisingly target tumor cells and distribute enwrapped payloads intensively. Existing challenges and prospects of bioinspired Ag NPs are also summarized. This review is expected to deliver perceptions about the progress of the next generation of bioinspired Ag NPs and their outstanding performances in various fields by promoting sustainable practices for fabricating optical sensing devices.
