Antibacterial and cytocompatibility study of modified Ti6Al4V surfaces through thermal annealing

Biomass-Templated Fabrication of Metallic Materials for Photocatalytic and Bactericidal Applications

“…The sizes of the growth inhibition zones around the newly prepared paper-templated silver and the paper-templated silver used for the second time against MRSA and E. coli were all larger than 1 mm, showing that the bactericidal effect of the paper-templated silver used twice is “good”. The inhibition zone was very small for the second time because the release rate of silver ions from the paper-templated silver gradually decreased with time [29], and because the surface of the paper-templated silver might be partially oxidized after the first use. The excellent antibacterial ability of the paper-templated silver results from the existence of silver and the release of silver ions, though the antibacterial efficiency of the paper-templated silver used for the second time was lower than that of the silver used the first time.…”

Bactericidal efficiency of micro- and nanostructured surfaces: a critical perspective

“…For the viability experiment, a common step is to rinse the substrates to remove non-adhered or weakly-adhered bacteria from the surface before conducting quantication test such as live dead analysis or colony counting. 31,33,37,38,40,45,47,51,53,55,56,59,63,[66][67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85] Commonly used rinsing methods are summarised in Table 1. Strikingly, the volumes or owrates used in the rinsing step of these studies are unspeci-ed, and the effect of stresses exerted on the loosely attached bacterial cells have not been accounted for.…”

“…Hence bacteria killing efficiency of MNSS quantied under static conditions is expected to be different under ow conditions as lysed bacteria remain on the surface till the end of the trial. 22,36,38,45,62,63,69,70,74,81,84,[96][97][98] Nanofeatures may not be able to pierce subsequent bacteria as the tips are covered with remains of previously lysed bacteria. Hence, sharpness, height, and spacing of the micro/nano features are compromised upon dead cell stagnation 99 as depicted in Fig.…”

Advances in layer-by-layer self-assembled coatings upon biodegradable magnesium alloys

“…After the insertion of orthopedic or dental Mg implants, the infection due to the formation of biofilm would be a severe complication which could lead to the local tissue lesions and failure of implant materials [99][100][101]. Actually, the antibiotics can be used to reduce the infections along with the surgery.…”
