Green synthesis of nanoparticles has many potential applications in environmental and biomedical fields. Green synthesis aims in particular at decreasing the usage of toxic chemicals. For instance, the use of biological materials such as plants is usually safe. Plants also contain reducing and capping agents. Here we present the principles of green chemistry, and we review plant-mediated synthesis of nanoparticles and their recent applications. Nanoparticles include gold, silver, copper, palladium, platinum, zinc oxide, and titanium dioxide.

Green synthesis of nanoparticles using plant extracts: a review

Tuning of metal oxides photocatalytic performance using Ag nanoparticles integration

Analysis of food, pharmaceutical, and environmental compounds is an inevitable issue to evaluate quality of the compounds used in human life. Quality of drinking water, food products, and pharmaceutical compounds is directly associated with human health. Presence of forbidden additives in food products, toxic compounds in water samples and drugs with low quality lead to important problems for human health. Therefore, attention to analytical strategy for investigation of quality of food, pharmaceutical, and environmental compounds and monitoring presence of forbidden compounds in materials used by humans has increased in recent years. Analytical methods help to identify and quantify both permissible and unauthorized compounds present in the materials used in human daily life. Among analytical methods, electrochemical methods have been shown to have more advantages compared to other analytical methods due to their portability and low cost. Most of big companies have applied this type of analytical methods because of their fast and selective analysis. Due to simple operation and high diversity of electroanalytical sensors, these types of sensors are expected to be the future generation of analytical systems. Therefore, many scientists and researchers have focused on designing and fabrication of electroanalytical sensors with good selectivity and high sensitivity for different types of compounds such as drugs, food, and environmental pollutants. In this paper, we described the mechanism and different examples of DNA, enzymatic and electro-catalytic methods for electroanalytical determination of drug, food and environmental compounds.

Electrochemical Sensors, a Bright Future in the Fabrication of Portable Kits in Analytical Systems

Palladium–Nickel nanoparticles decorated on Functionalized-MWCNT for high precision non-enzymatic glucose sensing

Synthesis of metal nanoparticles using plant extracts is one of the most simple, convenient, economical, and environmentally friendly methods that mitigate the involvement of toxic chemicals. Hence, in recent years, several eco-friendly processes for the rapid synthesis of silver nanoparticles have been reported using aqueous extracts of plant parts such as the leaf, bark, roots, etc. This review summarizes and elaborates the new findings in this research domain of the green synthesis of silver nanoparticles (AgNPs) using different plant extracts and their potential applications as antimicrobial agents covering the literature since 2015. While highlighting the recently used different plants for the synthesis of highly efficient antimicrobial green AgNPs, we aim to provide a systematic in-depth discussion on the possible influence of the phytochemicals and their concentrations in the plants extracts, extraction solvent, and extraction temperature, as well as reaction temperature, pH, reaction time, and concentration of precursor on the size, shape and stability of the produced AgNPs. Exhaustive details of the plausible mechanism of the interaction of AgNPs with the cell wall of microbes, leading to cell death, and high antimicrobial activities have also been elaborated. The shape and size-dependent antimicrobial activities of the biogenic AgNPs and the enhanced antimicrobial activities by synergetic interaction of AgNPs with known commercial antibiotic drugs have also been comprehensively detailed.

The ultimate aim of this study is to produce a composite of bimetallic
platinum-cobalt nanoparticles and reduced graphene oxide (Pt-Co@rGO) based biosensor
for the detection of ascorbic acid (AA), dopamine (DA) and uric acid (UA). Those are
biologically important molecules with the key functions for the human body.
Pt-Co@rGO was synthesized using a microwave-assisted technique and utilized for the
production of a highly sensitive and stable electrochemical biosensor. Detailed
spectral XPS and Raman analysis, XRD, and TEM/HR-TEM characterization were also
studied. Due to the superior activity and excellent conductivity of rGO,
well-separated oxidation peaks of these biomolecules is proven by DPV (differential
pulse voltammetry) and CV (cyclic voltammetry) measurements. The prepared
Pt-Co@rGO-based biosensor showed high electrochemical activity, a broad linear
response, high sensitivity, and acceptable limit of detection values for individual
and simultaneous determination of AA, DA, and UA, under optimized conditions. The
linear range of Pt-Co@rGO was found to be 170–200; 35–1500 and 5–800 µM for AA, DA,
and UA, respectively. Moreover, the detection limit of the prepared composite was
calculated as 0.345; 0.051; 0.172 µM for AA, DA, and UA, respectively. In the field
of electrochemical biosensors, Pt-Co@rGO based sensor is highly promising due to its
superior sensitivity and good selectivity properties.
