Antimicrobial activity of eumelanin-based hybrids: The role of TiO 2 in modulating the structure and biological performance

Photocatalytic Activity of Nanostructured Titania Films Obtained by Electrochemical, Chemical, and Thermal Oxidation of Ti6Al4V Alloy—Comparative Analysis

“…The studies on titanium dioxide and the materials produced on its basis are a good example of the efforts to determine the impact of individual structural and morphological parameters on properties and application possibilities of modern materials. TiO 2 materials and nanomaterials, now are often used in various applications, such as self-cleaning surfaces [1][2][3], anti-fogging mirrors [4,5], antimicrobial coatings, [6][7][8][9] electrochromic devices [10][11][12], rechargeable batteries [13,14], and sensors [15,16]. They can also be applied in medicine [17][18][19][20], automotive [21,22], and in photocatalytic environmental cleaning of water and air [23][24][25][26].…”

Bioinspired hybrid eumelanin–TiO2antimicrobial nanostructures: the key role of organo–inorganic frameworks in tuning eumelanin's biocide action mechanism through membrane interaction

“…10 Eumelanins are truly multifunctional biopolymers, 11 performing several biological functions such as photoprotection, photosensitization, free radical quenching, metal ion chelation and even intrinsic antimicrobial efficacy and biolm inhibition without any photosensitization. 1,12,13 Notably, recent emerging evidence has disclosed and investigated the potential of eumelanin and eumelanin based materials as valuable antimicrobial agents, [14][15][16][17] but mechanisms and processes behind biocide activity still remain poorly understood. 1 Indeed some papers argue that antimicrobial action of eumelanins relies on ROS generation.…”

Design and Application of Magnetic Photocatalysts for Water Treatment. The Effect of Particle Charge on Surface Functionality

“…UV-vis light driven photooxidation of persistant organic pollutants [1][2][3], removal of odors from enclosed space [4], destruction of bacteria with low intensity radiation [5] and self-cleaning surfaces [6] are examples of the potential of nanostructure-based photocatalysts. One of major challenges in photocatalysis application is separation and recovery of nanosized TiO 2 particles from the treated water, since sedimentation is usually insufficient, while filtration is costly [7].…”
