Current Analytical Chemistry - Volume 18, Issue 5, 2022

The design of high-performance electrochemical sensor and biosensor platforms has attracted much interest for the sensitive and selective detection of emergent biomarkers. The electrochemical sensor offers numerous advantageous features including cost-effectiveness and ease of miniaturization, rapid and online monitoring, simultaneous detection ability, etc., which have captivated the potential interdisciplinary re Read More

Background: Speciation analysis is defined as the identification and/or measurement of the quantities of one or more individual chemical species in a sample. The knowledge of elemental species provides more complete information about mobility, bioavailability and the impact of elements on ecological systems or biological organisms. It is no longer sufficient to quantitate the total elemental content of samples to define toxicit Read More

Background: Biosensors are analytical devices that include a sample-delivery approach between a biological recognition element and a transducer required to convert the physicochemical change produced from the interaction of biological molecule-receptor interaction into a signal. The immunosensor is a special type of biosensor that includes an antibody as a biorecognition element to detect analytes as antigens. In ma Read More

Background: This is the first review on Poly(diphenylamine) and its nanohybrids, which covers about 181 references demonstrating the brief discussion on the theoretical studies, chemical, electrochemical and other-phase preparation techniques, polymerization and oxidation-reduction (redox) mechanisms, physicochemical and electrochemical properties along with electrochemical sensors and spectroscopic application Read More

Background: The interest in breath analysis for non-invasive disease diagnosis of the scientific community has been increased over the past decade. This is due to the exhalation of prominent volatile organic compounds (VOCs) corresponding to the metabolic activities in the body and their concentration variation. To identify these biomarkers, various analytical techniques have been used in the past and the threshold c Read More

Background: Sample preparation has gained significant recognition in the chemical analysis workflow. Substantial efforts have been made to simplify the comprehensive process of sample preparation that is focused on green sample preparation methodology, including the miniaturization of extraction method, elimination of the sample pre-treatment as well as the posttreatment steps, elimination of toxic as well as hazard Read More

Background: Microplastics are found to be one of the major emerging contaminants in the environment. Various environmental occurrences cause the macro plastics to degrade slowly into microplastics. Microplastics present in the water bodies may enter into the fish’s body through ingestion of food and also get adsorbed onto the surface of their gills or skin. Objective: Microplastics of polyethylene were chosen to investigate t Read More
