Comparison of Next-Generation Sequencing Systems

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

A sensitive hydrogen peroxide (H2O2) sensor was constructed based on graphene-Pt (RGO-Pt) nanocomposites and used to measure the release of H2O2 from living cells. The graphene and Pt nanoparticles (Pt NPs) were modified on glassy carbon electrode (GCE) by the physical adsorption and electrodeposition of K2PtCl6 solution, respectively. Through characterization by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), it was observed that the electrodeposited Pt NPs were densely covered and well distributed on the entire graphene surface. Electrochemical study demonstrates that the RGO-Pt nanocomposites modified glassy carbon electrode exhibited a high peak current and low overpotential toward the reduction of H2O2. The relevant detection limit of H2O2 is ∼0.2 μM with a wide linear range from 0.5 μM to 3.475 mM, displaying a much higher sensitivity (459 ± 3 mA M(-1) cm(-2), n = 5) than that of Pt nanoparticles or graphene modified electrode. This novel biosensor can measure the H2O2 release from living cells because of its low detection limit, wide linear range, and higher sensitivity.

A chemiluminescence sensor for the determination of hydrogen peroxide

Nanocomposite material consists out of several phases where at least one, two or three dimensions are in nanometer range. Taking material dimensions down to nanometer level creates phase interfaces which are very important for enhancement of materials properties. The ratio between surface area and volume of reinforced material used during nanocomposites preparation is directly involved in understanding of structure-property relationship. Nanocomposties offer opportunities on completely new scales for solving obstacles ranging from medical, pharmaceutical industry, food packaging, to electronics and energy industry. This paper presents main ideas behind nanocomposites and discusses matrix materials upon which nanocomposites can be divided in three classes; metal matrix, ceramic matrix and polymer matrix nanocomposites. The goal is to explain which raw material and technique is most suited for processing of a particular nanocomposites as well as application, advantages and drawbacks of nanocomposites. Nanotechnology is still in development and current limitations hinder global transition from macro-scale to nano-scale.

Food safety is a scientific field which includes a number of routines and inspections at every stage of the food chain that should be adopted to avoid potentially dangerous health risks. Novel and efficient solutions across the supply chain are the consequence of constant upgrades of information and communication technologies. With the help of internet of things (IoT) connected testing equipment, food quality can be monitored at any point from farm to table, connecting at the same time food producers, transportation and hospitality/retail companies. Relying on the fact that food transporting and packaging units are the most critical points in food production, the survey of IoT applications in food packaging and transportation is given in this paper. To demonstrate the significance of IoT appliance and defined concepts, a proposal of low cost solution based on IoT for real-time food traceability and monitoring in food transportation process is presented.
