In recent years, interest in nanotechnology has increased exponentially due to enhanced progress and technological innovation. tissue engineering, the development of metallic nanoparticles been amplified, especially their antibacterial properties. Another important characteristic metal NPs is that they enable high control over features developed scaffolds (optimizing mechanical strength offering controlled release bioactive agents). Currently, main concern related method synthesis oxide environmental impact. The physical chemical uses toxic agents could generate hazards or exert carcinogenicity/environmental toxicity. Therefore, a greener, cleaner, more reliable approach needed. Green synthetic come as solution counter aforementioned limitations. Nowadays, green preferred because it leads prevention/minimization waste, reduction derivatives/pollution, use non-toxic (safer) solvents. This not only biomass sources reducing for salts. biomolecules also cover synthesized act situ capping agents. Further, involvement formation process reduces toxicity, prevents nanoparticle agglomeration, improves antimicrobial activity nanomaterial, leading possible synergistic effect. study aims provide comprehensive review nanoparticles, from routes, selected solvents, parameters latest application biomedical field.

Silk fibroin-based scaffolds for wound healing applications with metal oxide nanoparticles

Journal of Drug Delivery Science and Technology, Journal Year: 2024, Volume and Issue: 96, P. 105689 - 105689

Published: April 21, 2024

In the last few years, wound healing and development of "ideal" biomaterials that provide quick recovery minimize scarring have represented one most important priorities researchers. this direction, silk fibroin (SF) scaffolds gained substantial awareness, as a promising polymer owing to their increased biocompatibility, outstanding mechanical properties, biodegradability, especially tensile strength. Furthermore, SF is acknowledged accelerate process by encouraging cell growth proliferation, also migration different types cells are included in stages process. Therefore, metal oxide nanoparticles (NPs), such iron (FeO), copper (CuO), zinc (ZnO), or magnesium (MgO) NPs, been extensively researched for antimicrobial properties ability enhance tissue regeneration addition SF. When introduced within scaffolds, these NPs impart enhanced including improved scaffold stability durability. Moreover, presence could increase biocompatibility facilitating adhesion, migration, ultimately promoting processes. The incorporation other natural polymers into has thus emerged favorable method therapeutic potential developed biomaterial. This review aims an overview advancements containing applications.

The excessive use of virgin materials for manufacturing cementitious in the building and construction industry creates detrimental environmental effects. integration waste composites promote sustainable opportunities within industry. This paper presents a systematic review synthetic textile cardboard fibres concrete conjunction with infrequently used additives such as gypsum, metakaolin, alumina zinc oxide. nature polyester nylon facilitates their into high alkaline environments. Kraft fibres, derived from cardboard, exhibit tensile strength but also absorb water, limiting construction. However, by employing coating applications, these limitations can be mitigated. Gypsum prolongs setting times, improves workability, enhances sulphate resistance concrete. Metakaolin's reactivity calcium hydroxide results improved strength, density, durability. Alumina oxide enhance mechanical thermal characteristics. Whereas oxide, known its UV protection antimicrobial properties has retarder effect improve longevity extreme Scanning electron microscope images demonstrate sustained durability features composite whereas, kraft exhibited deterioration properties. Fibre bonding aspects material varied each matrix environment. corresponded to microstructural response fibrous materials. findings this sustainability when integrating additive designs.
