“…Despite the potential application of these nanomaterials, sensitivity, dissolution at high pH, and integration of expensive polymer for increasing the biosensing properties are the main drawbacks. 33,34 Anisotropic GNSs provide extraordinary biosensing platforms owing to their unique optical and electronic features, high surface-to-volume ratio, conductivity, catalytic properties, biocompatibility, low toxicity, and the ability for immobilization and high load of biological molecules like DNA while maintaining their properties. 35,36 According to Table 2, various detection techniques have been used to identify the target sequence of E. coli O157:H7.…”

“…Wastewater treatment is the process of removing, eliminating, or inactivating the majority of contaminants and disease-causing organisms, such as influenza viruses from wastewater (Anand et al, 2020). Globally, wastewater poses significant risks of infections, which accounts for around a million fatalities each year, nearly half of which are children and more than 90% of which occur in underdeveloped nations.…”

“…Currently, there are three recommended antiviral medications, namely oseltamivir, zanamivir, and peramivir, for the treatment of influenza. These drugs act by bolstering the immune system’s ability to combat viral infections and reducing the viral load present in the body (Anand et al, 2020). Rapid diagnosis and treatment are crucial, as antiviral drugs can effectively treat both influenza A and B infections when administered within 48 hours of the onset of flu symptoms.…”

Influenza has historically been and remains a significant global health concern, causing substantial illness worldwide. Influenza is a serious public health issue in both industrialized and developing nations and it is characterized as an acute respiratory illness resulting from infection with influenza virus. Influenza viruses are RNA viruses with a negative sense and enveloped structure. These viruses possess segmented genomes, with influenza A and B viruses being the prevalent types affecting human populations. These viruses have been associated with disease outbreaks in some regions of the world as a result of excrement being introduced into the environment. Given the global implications of influenza and the limited availability of data for many countries, particularly in the African region where the prevalence and incidence of influenza remain largely unknown, there is a lack of published information regarding the detection of influenza viruses. Therefore, the purpose of this paper is to examine or review the frequency of influenza virus detection in wastewater samples, serving as an initial step toward gaining a better understanding of the burden of influenza. This includes exploring its epidemiology, the consequences of severe influenza infections, and the development of strategies to enhance supportive care and virus-specific therapies in resource-constrained, low-income settings.

“…Size- and shape-dependent toxicity is reported for Ag NPs, CNTs and many other metal NPs. The size of NPs (from 1 to 100 nm) are akin to the size of protein globules (2–10 nm), DNA helix (2 nm) and thicknesses of cell membranes (10 nm), allowing easy entry to cells and cell organelles [ 189 ].…”

Clean and safe water is a fundamental human need for multi-faceted development of society and a thriving economy. Brisk rises in populations, expanding industrialization, urbanization and extensive agriculture practices have resulted in the generation of wastewater which have not only made the water dirty or polluted, but also deadly. Millions of people die every year due to diseases communicated through consumption of water contaminated by deleterious pathogens. Although various methods for wastewater treatment have been explored in the last few decades but their use is restrained by many limitations including use of chemicals, formation of disinfection by-products (DBPs), time consumption and expensiveness. Nanotechnology, manipulation of matter at a molecular or an atomic level to craft new structures, devices and systems having superior electronic, optical, magnetic, conductive and mechanical properties, is emerging as a promising technology, which has demonstrated remarkable feats in various fields including wastewater treatment. Nanomaterials encompass a high surface to volume ratio, a high sensitivity and reactivity, a high adsorption capacity, and ease of functionalization which makes them suitable for application in wastewater treatment. In this article we have reviewed the techniques being developed for wastewater treatment using nanotechnology based on adsorption and biosorption, nanofiltration, photocatalysis, disinfection and sensing technology. Furthermore, this review also highlights the fate of the nanomaterials in wastewater treatment as well as risks associated with their use.
