Green analytical chemistry metrics for evaluating the greenness of analytical procedures

Green analytical chemistry(GAC)focuses on mitigating the adverse effects of analytical activities on human safety,human health,and environment.In addition to the 12 principles of GAC,proper GAC tools should be developed and employed to assess the greenness of different analytical assays.The 15 widely used GAC metrics,i.e.,national environmental methods index(NEMI),advanced NEMI,assessment of green profile(AGP),chloroform-oriented toxicity estimation scale(ChlorTox Scale),Analytical Eco-Scale,Green Certificate Modified Eco-Scale,analytical method greenness score(AMGS),green analytical procedure index(GAPI),ComplexGAPI,red-green-blue(RGB)additive color model,RGB 12 algorithm,analytical greenness calculator(AGREE),AGREE preparation(AGREEprep),HEXAGON,and blue applicability grade index(BAGI),are selected as the typical tools.This article comprehensively presents and elucidates the principles,characteristics,merits,and demerits of 15 widely used GAC tools.This review is helpful for researchers to use the current GAC metrics to assess the environmental sustainability of analytical assays.

Analytical Approach to Clusters in near Critical CO2

Clusters greatly influence thermophysical properties of near critical gases. The cluster structures of supercritical fluids in general and Carbon Dioxide especially are important for the advanced supercritical fluid technologies and analytics development. The paper extends to near critical densities the developed earlier methods to extract the clusters’ properties from Online Electronic Database of NIST on thermophysical properties of fluids. This Database contains a hidden knowledge of cluster fractions’ properties in real gases. The discovered earlier linear chain clusters dominate at intermediate densities. Their properties can be extrapolated to high density gases, thus opening the way to study large 3D clusters in near critical zone. The potential energy density of a gas, cleared from the chain clusters’ contribution, reflects only the 3D clusters’ characteristics. A series expansion of this value by the Monomer Fraction density discovers properties of n-particle 3D clusters. The paper demonstrates a discrete row of 3D clusters’ particle numbers and gives estimations for bond energies of these clusters.

Aggregation-based analytical chemistry in point-of-care nanosensors

It is crucial to realize the point-of-care(POC)testing of harmful analytes,capa-ble of saving limited agricultural resources,assisting environmental remediation,ensuring food safety,and enabling early disease diagnosis.Compared with other conventional POC sensing strategies,aggregation-based analytical chemistry facil-itates the practical-oriented development of POC nanosensors by altering the aggregation status of nanoprobes through the action of multiple aggregation-induced“forces”originating from the targets.Herein,we have proceeded with a comprehensive review focusing on the aggregation-based analytical chemistry in POC nanosensors,covering aggregation-induced“forces”,aggregation-induced signal transductions,aggregation-induced POC nanosensing strategies,and their applications in biomolecular monitoring,food safety analysis,and environmental monitoring.Finally,challenges existing in practical applications have been fur-ther proposed to improve their sensing applications,and we expect our review can speed up the development of cost-effective,readily deployable,and time-efficient nanosensors through aggregation-based analytical chemistry.
