Recent advancement in development and modification of nanofibrous matrix for the application in sensing and remediation of water pollutants

Abstract

AbstractElectrospun nanofibers have been extensively investigated in recent years for the generation of various advanced sensing technique like high efficiency biosensors, chemosensors, colorimetric sensing strip, and nanofibrillar-based biosorbent for waste water management, remediation and environmental monitoring. The present review article highlights various different types of conventional sensors, their limitations and the further advancement towards development of highly sensitive sensor with faster response time using functionalized nanofibrous matrix. It also explains the various approaches for the generation of nanofibrous matrix through melt blowing, force spinning, template melt extrusion and electrospinning methods and their further modification with suitable probe for the detection and elimination of various water contaminants. This review discussed various nanofibrous matrices that have been modified for the sensing and remediation of heavy metals such as mercury (Hg), lead (Pb), copper (Cu), organic pollutants such as dye, petroleum, phenolic compounds, and microorganisms such as Escherichia coli (E. coli), BVDV (bovine viral diarrhoea virus), Staphylococcus aureus (S. aureus) and Candida albicans (C. albicans). Finally, the various challenges and future perspectives associated with the usage of nanofibrous matrix-based sensors for detection and remediation of water pollutant are discussed.
