“…It is important to note, that a size result by DLS involved HD of the nanoparticles in suspension. The different 7 values observed for the same AuNPs@Damiana samples were a consequence of the cloud formed by molecules coming from the T. difussa extracts on the nanoparticle surface, which resulted in larger HD [31]. On the other hand, ZP did not show any isoelectric point, which meant the AuNPs@Damiana surface charge was always negative from pH 3 to 11 due to anion adsorption on the particle surface in all ranges.…”

Interest in green synthesis methods for nanoparticle production with potential use in biology, pharmacy, and medicine is a forefront field in research. Among the routes described in the literature, the use of plant extracts as reducing and capping agents is one of the most promising. Turnera diffusa commonly called Damiana is a wild shrub traditionally used as aphrodisiac, diuretic, and for cancer and diabetes treatments. Its extracts are rich in flavonoid, phenolic, terpenoid, and other active compounds that possess antiallergic, antiviral, and antifungal activities. Besides, flavonoids have been reported to have a redox potential sufficient for metal ion reduction. Thus, this study reports a novel and facile method for green gold nanoparticle (AuNPs) synthesis using T. diffusa extracts. The samples were fully characterized by scanning electron microscopy, acrylonitrile butadiene styrene ultraviolet-visible, dynamic light scattering, X-ray photoelectron, and inductively coupled plasma optical emission spectroscopies. The results showed high efficiency of T. diffusa extracts to reduce and stabilize the AuNPs which showed spherical shape, 24 nm diameter, negative surface charge, and high colloidal stability at biological pH and alkaline media. Additionally, its antimicrobial activity was evaluated showing high antiseptic capacity against gram-negative Salmonella enteritis and Escherichia coli ATCC 8739 bacteria.

“…With the rapid development of nanotechnology, apart from the afore-mentioned nanoparticles, many other types of functional nanomaterials with antiviral activity have emerged recently. For instance, Palestino et al prepared rare-earth upconverting Gd 2 O 3 :Tb 3+ /Er 3+ fluorescent nanoparticles as microcarriers of a Zika virus antigenic peptide with adjuvant properties [112]. Mazurkow et al developed the spray-dried alumina granules modified with copper oxide nanoparticles and assessed the effect of copper oxidation state on virus removal capacity [113].…”

Research on highly effective antiviral drugs is essential for preventing the spread of infections and reducing losses. Recently, many functional nanoparticles have been shown to possess remarkable antiviral ability, such as quantum dots, gold and silver nanoparticles, nanoclusters, carbon dots, graphene oxide, silicon materials, polymers and dendrimers. Despite their difference in antiviral mechanism and inhibition efficacy, these functional nanoparticles-based structures have unique features as potential antiviral candidates. In this topical review, we highlight the antiviral efficacy and mechanism of these nanoparticles. Specifically, we introduce various methods for analyzing the viricidal activity of functional nanoparticles and the latest advances in antiviral functional nanoparticles. Furthermore, we systematically describe the advantages and disadvantages of these functional nanoparticles in viricidal applications. Finally, we discuss the challenges and prospects of antiviral nanostructures. This topic review covers 132 papers and will enrich our knowledge about the antiviral efficacy and mechanism of various functional nanoparticles.

“…Second is the modification of NPs by antiviral agent of HCV (Pollock et al 2010 ). Rare earth metal NPs have been used as antiviral agent for Zika virus (Ortega-Berlanga et al 2020 ), while alumina modified with CuO NPs have been utilized as functional antiviral agent for HSV1 (Mazurkow et al 2020 ) (Tavakoli and Hashemzadeh 2020 ). It has been suggested in Nabila et al ( 2019 ) and Derbalah et al ( 2019 ) that the NiO can be used for inactivating CMV.…”

Novel corona virus (COVID-19) pandemic in the last 4 months stimulates the international scientific community to search for vaccine of antiviral agents suitable for in activating the virus inside and outside the human body. More than 4 million people globally are infected by the virus and about 300,000 dead cases until this moment. The ventilation and airborne filters are also investigated aiming to develop an efficient antiviral filtration technology. Human secretion of the infected person as nasal or saliva droplets goes as airborne and distributes the virus everywhere around the person. N95 and N98 filters are the must use filters for capturing particles of sizes around 300 nm. The average size of the novel corona virus (COVID-19) is 100 nm and there is no standard or special filter suitable for this virus. The nanoparticle-coated airborne filter is a suitable technique in this regard. While the efficiency of this type of filters still needs to be enhanced, new developed nanofiber filters are proposed. Most recently, the charged nanofiber filters of sizes below 100 nm are developed and provide an efficient viral filtration and inactivation. The efficiency of filter must be kept at accepted level without increasing the pressure drop. The present review outlines the most efficient antiviral nanoparticles including the recent functional nanoparticles. The filtration theory, filtration modeling, filter testing, and different types of filter with special concentration on the charged nanofiber filter were discussed. The charged nanofiber filter able to capture novel corona virus (COVID-19) with 94% efficiency and a pressure drop less than 20 MPa.
