“…The green production of G-TiO 2 nanoparticle optical endurance was measured from UV-DRS analysis. The optical absorption edge is located at The suppressed charge carriers increased the reactive oxygen species and hydroxyl radical formations [30]. These productions promote the reduction of pollution from environment through the photocatalysis and bacterial degradation activity.…”

Metal oxide photocatalyst is one of the promising photocatalysts in the water remediation process. The present work is aimed at synthesizing the green production of TiO2 (G-TiO2) nanoparticles from mulberry plant extract. Plant phytochemicals serve a different role to produce the nanophase particles. The bioreductant is safer and noxious free compound for synthesizing the G-TiO2 nanoparticles. The synthesized G-TiO2 nanoparticles in anatase phase and their crystallite size of 24 nm were characterized from X-ray diffraction analysis. The Ti-O bonding and plant derivatives and their reduction were confined from FTIR analysis. The wide bandgap of G-TiO2 nanoparticles (3.16 eV) and their optical characterization were captured from UV-DRS analysis. The spherical surface morphology and their Ti and O elemental configurations were characterized from FESEM with EDX technique. The photocatalytic dye degradation was examined against methylene blue dye, and their pseudo-first-order kinetics were evaluated. The cyclic experiments declared their catalytic potential. The bacterial resistance of G-TiO2 nanoparticles was examined against gram-positive and gram-negative bacteria. Hence, the catalytic potential and bacterial stability of G-TiO2 nanoparticles are the powerful candidate for water remediation and biomedical applications.

“…Chitosan materials filled with selenium nanoparticles were proven to be effective against infections in burnt wounds [ 52 ]. Additionally, scaffolds based on silk fibroin-collagen loaded with titania nanoparticles were adequate for skin tissue regeneration [ 53 ]. Polyuretanes, due to their wide range of mechanical properties, varying from flexible to rigid materials have been widely used in many industrial and biomedical applications [ 5 ].…”

Infections caused by bacteria are one of the main causes of mortality in hospitals all over the world. Bacteria can grow on many different surfaces and when this occurs, and bacteria colonize a surface, biofilms are formed. In this context, one of the main concerns is biofilm formation on medical devices such as urinary catheters, cardiac valves, pacemakers or prothesis. The development of bacteria also occurs on materials used for food packaging, wearable electronics or the textile industry. In all these applications polymeric materials are usually present. Research and development of polymer-based antibacterial materials is crucial to avoid the proliferation of bacteria. In this paper, we present a review about polymeric materials with antibacterial materials. The main strategies to produce materials with antibacterial properties are presented, for instance, the incorporation of inorganic particles, micro or nanostructuration of the surfaces and antifouling strategies are considered. The antibacterial mechanism exerted in each case is discussed. Methods of materials preparation are examined, presenting the main advantages or disadvantages of each one based on their potential uses. Finally, a review of the main characterization techniques and methods used to study polymer based antibacterial materials is carried out, including the use of single force cell spectroscopy, contact angle measurements and surface roughness to evaluate the role of the physicochemical properties and the micro or nanostructure in antibacterial behavior of the materials.

This review supplies a report on fresh advances in the field of silk fibroin (SF) biopolymer and its blends with biopolymers as new biomaterials. The review also includes a subsection about silk fibroin mixtures with synthetic polymers. Silk fibroin is commonly used to receive biomaterials. However, the materials based on pure polymer present low mechanical parameters, and high enzymatic degradation rate. These properties can be problematic for tissue engineering applications. An increased interest in two- and three-component mixtures and chemically cross-linked materials has been observed due to their improved physico-chemical properties. These materials can be attractive and desirable for both academic, and, industrial attention because they expose improvements in properties required in the biomedical field. The structure, forms, methods of preparation, and some physico-chemical properties of silk fibroin are discussed in this review. Detailed examples are also given from scientific reports and practical experiments. The most common biopolymers: collagen (Coll), chitosan (CTS), alginate (AL), and hyaluronic acid (HA) are discussed as components of silk fibroin-based mixtures. Examples of binary and ternary mixtures, composites with the addition of magnetic particles, hydroxyapatite or titanium dioxide are also included and given. Additionally, the advantages and disadvantages of chemical, physical, and enzymatic cross-linking were demonstrated.
