A new green deposition of silver nanoparticles (AgNPs) on polymers was proposed in this work. In-situ synthesis of AgNPs on polymers was achieved via a green procedure using natural reducing agents, which are Ageratum conyzoidez and Mikania micrantha. Several characterizations of the treated polymers such as color transformation, surface morphology, elemental contents, and water absorption were comprehensively evaluated. For the application, the treated polymers were then tested against waterborne bacteria, which are Escherichia coli and Bacillus cereus. Rapid deposition of AgNPs via the presently biological method can be successfully achieved as observed via surface morphology analysis and energy dispersive X-ray investigation. Water absorption capabilities of the polymers can be decreased after attaching with AgNPs, which can also probably contribute to the enhancement of their antibacterial activities. This study observed that the treated polymers showed excellent antibacterial activities against Escherichia coli and Bacillus cereus. The findings of this study are useful in designing water purifiers to disinfect contaminated water.

“…Toxicity was lower than that reported for chitosan-silver nanoparticle-fluoride composites, with mortality rates above 60 % at a concentration of 1000 mg/L (68). Toxicity was lower than that observed for PVP-stabilized AgNP and AgNw with mortality rates of 20 % and 100 %, respectively, at a concentration of 100 mg/L after 48 h of exposure (69).…”

This was our first year of a new (risky) experience, assuming a totally online edition, new editorial procedures, organization, and layout. Happening in a year definitively marked by the extraordinary global crisis caused by this SARS COVID19 changing the definition of "normality" in all aspects of our life.Biomedical and Biopharmaceutical Research journal is no exception. The year of our full open access was simultaneously, the year of many other changes and impacts. Crisis always give space to opportunities, and we did got ours. BBR journal achieved to be more professional and available. Closer to the authors, to the reviewers and editors interacting in a regular way. Stronger in its processes and therefore more rigorous and transparent, in the right track for consolidation. This is no doubt, the most productive editorial year ever in the history of BBR. Our options were clearly accepted by our authors. We read these outcomes as a trust token that we deeply appreciate. Our success is their success. Therefore, we will continue to do more and better for this instrument of scientific culture specially conceived and reasoned in the common language of our Portuguese speaking communities.We stress our independent character, non-profit defined, exclusively based in the science and education, wholeheartedly dedicated to the growth of scientific culture. This is part of our foundation and our compromise for the future. This 2020 closure number includes two articles in the Nutrition and Food Sciences section, six articles in the Biomedical Sciences section and six others in the Biopharmaceutical Sciences section. Three other documents complete this number -the Proceedings Book of the 55th Annual Congress of the Brazilian Society of Physiology which included the 1st Portuguese-Brazilian Physiology Meeting organized by both countries' (sister) Physiology Societies, the Proceedings Book from the 2020 CBIOS Science Sessions, and the Proceedings Book from the IV CBIOS Seminar 2020.

“…This feature confers a high potential hazard to the environmental release of AgNPs, since their biocidal properties are not only restricted to microorganisms. In fact, AgNPs are largely documented to be toxic to aquatic biota [30,135] including freshwater [18,39,136] and marine species [34,[136][137][138][139][140] (Figure 3).…”

Silver Nanoparticles for Water Pollution Monitoring and Treatments: Ecosafety Challenge and Cellulose-Based Hybrids Solution

Silver nanoparticles (AgNPs) are widely used as engineered nanomaterials (ENMs) in many advanced nanotechnologies, due to their versatile, easy and cheap preparations combined with peculiar chemical-physical properties. Their increased production and integration in environmental applications including water treatment raise concerns for their impact on humans and the environment. An eco-design strategy that makes it possible to combine the best material performances with no risk for the natural ecosystems and living beings has been recently proposed. This review envisages potential hybrid solutions of AgNPs for water pollution monitoring and remediation to satisfy their successful, environmentally safe (ecosafe) application. Being extremely efficient in pollutants sensing and degradation, their ecosafe application can be achieved in combination with polymeric-based materials, especially with cellulose, by following an eco-design approach. In fact, (AgNPs)–cellulose hybrids have the double advantage of being easily produced using recycled material, with low costs and possible reuse, and of being ecosafe, if properly designed. An updated view of the use and prospects of these advanced hybrids AgNP-based materials is provided, which will surely speed their environmental application with consequent significant economic and environmental impact.
