The use of electrochemical sensors for sensitive disease diagnosis and detecting various species with pharmacological,therapeutic,industrial,food-related,and environmental origins is now widely accepted.A catalytic or binding event resulting from the sensor’s electroactive component recognizing its analyte creates an electrical signal proportionate to the analyte concentration,which is then monitored by a *** development of morphologically distinct metal and metal oxide nanoparticles formed from first-row transition elements(Mn,Cr,Fe,Co,Ti,Ni,Cu,Zn)and noble metals(pt,Au,Ag,pd)is described in this *** effect of these metal nanoparticles has been studied using Tetracyanoquinodimethane(TCNQ),Ferrocene,and other organic compounds as electroactive species using carbon paste-modified *** sensors,mostly based on ferrocene,are exceedingly sensitive,selective,affordable,and for detecting numerous biomolecules like glucose,dopamine,NADH,ascorbic acid,and a few dyes and are simple to *** recent decades,charge transfer organic species-based chemosensors have become a prominent study *** paper outlines current developments in electrochemical biosensors based on transition metal nanoparticles,covering glucose,ascorbic acid,uric acid,and other inorganic and organic *** importance of transition metal and transition metal oxide nanoparticles as potential electrode modifiers for developing sensors is highlighted.A discussion of the present problem and possible solutions,and plausible future directions marks the review’s conclusion.

Vehicular emissions are considered one of the major anthropogenic sources of greenhouse gases and poor air quality in metropolitan *** study aims to see the correlation of CO_(2),CH_(4),and CO through monitoring over a period from December 2020 to October 2021 covering three seasons’winter,summer,and monsoon at two different traffic locations of Delhi having different traffic volumes,road patterns,and traffic *** annual average morning concentration of CO_(2),CH_(4)and CO was found(533±105),(7.3±3.1),(10.7±3.0)ppm at Najafgarh and(480±70),(5.2±1.8),(7.8±2.8)ppm at Rajendra place,respectively.A relationship between concentration of all three gases and meteorological parameters such as temperature,humidity,wind speed and wind direction has also been investigated using pearson correlation coefficient and pollution rose diagram.A comparable pattern in concentration was observed for all three gases in spatial(location)and temporal(diurnal)*** concentration trend of CO_(2)in different seasons is winter>summer>monsoon,while in the case of CH_(4)winter=summer>monsoon but not any seasonal trend was noted in CO *** is observed that CO_(2)has a good relation with CO(a tracer for vehicular emission)in terms of diurnal variation,whereas,CH_(4)does not represent a relation with CO and CO_(2)diurnally,suggesting that vehicles are the source of CO_(2)but not much contributing to other greenhouse gases like CH_(4).
