Sol-gel synthesized rutile TiO2 nanoparticles loaded with cardamom essential oil: Enhanced antibacterial activity

Synthesis and Applications of Green Synthesized TiO2 Nanoparticles for Photocatalytic Dye Degradation and Antibacterial Activity

“…When these colours are released into rivers or lakes, they create unsightly pollution, physiologically increasing eutrophication, toxicity, and disruption in aquatic life. Traditional water treatments are not completely degrading the dyes because such colours are chemically stable [35][36][37]. 4…”

“…The catalytic degradation efficiency was found to be very high from 0 min to 30 min and reached to a maximum of 96% at 120 min due to the presence of G-TiO 2 nanoparticles (Figure 6 . When exposed to ultraviolet light, a photon of energy hv is emitted; the photon of energy hv greater than the band gap stimulates the electron (e -) from the valence band to the conduction band and leaves a hole (h + ) on the valence band, resulting in the production of an electron-hole pair [35][36][37][38][39]. The OH * radical is formed when photogenerated holes on the valence band react with dyes or water attached to the surface.…”

Alginate as a Promising Biopolymer in Drug Delivery and Wound Healing: A Review of the State-of-the-Art

“…ALG gelation occurs via one of two mechanisms: (1) external gelation, in which cations enter the ALG system from the outside, or (2) internal gelation, in which cations escape the ALG structure. ALG-based particles of a variety of dimensions can be produced and categorized into various categories: (1) macroparticles, such as that of drug or vitamin tablets, may be seen by the naked eye; (2) microparticles vary significantly in size from a few microns to several millimeters; and (3) nanoparticles have a diameter ranging between 1 to 100 nm [ 101 , 102 , 103 , 104 ]. The most popular method for producing ALG particles is the drop-by-drop expulsion of an ALG solution through a needle in a cationic bath.…”

Bacterial cellulose as a potential biopolymer in biomedical applications: a state-of-the-art review

“…To impart antibacterial properties to BC-based wound dressings, several antibacterial nanoparticles have been employed, among which TiO 2 NPs have gained interest due to their biocompatibility, powerful oxidation, and antibacterial properties. 13,327 However, irradiation affects some of the characteristics of TiO 2 given that it is frequently excited under damaging UV radiation due to its high bandgap ( E g = 3.20 eV) and it can only utilize 5% of the available solar energy to convert into its active form. Consequently, the absorption of TiO 2 should be relocated to the visible part of the electromagnetic radiation spectrum to enable the full benefit of sunlight.…”
