Development of micropatterning polyimide films for enhanced antifouling and antibacterial properties

Modification of Ti6Al4V surface properties by combined DLW-DLIP hierarchical micro-nano structuring

“…In this sense, the obtained results are somehow disruptive with relation to the well known evolution of hydrophobicity with roughness in DLIP generated microstructures (as reported, i.e. by Cuello et al [40] and Guenther et al [41]).…”

Molecular mechanisms of the antibacterial activity of polyimide fibers in a skin-wound model with Gram-positive and Gram-negative bacterial infection in vivo

“…Then, relative fluorescence units (RFU) were determined using a broad spectrum reader (Thermo Scientific, Varioskan Flash) equipped with a filter (excitation: 480 nm; emission: 500 nm) for SYTO 9 stain and another filter (excitation: 490 nm, emission: 635 nm) for propidium iodide stain. 40 …”

“…50 It was also reported that a commercial biomedical PI lm modied by topography and chemistry exhibited signicantly decreased bacterial (P. aeruginosa) adhesion and antibacterial properties. 40 2-Methacryloyloxyethyl phosphorylcholine-modied hyperbranched polyimide exhibited improved biocompatibility and reduced the number of bacterial adhesion. 51 This research of using PI combined with other reagents evokes promising further applications as antibacterial dressings; however, more attention needs to be paid to the effectiveness and safety of this compound.…”

Molecular dynamics model for the antibactericity of textured surfaces

“…While several works have found clear correlations between roughness and retention of specific bacteria types [13,14,15,16], others have found that surface roughness has negligible e↵ects on adhesion [17,18,19].…”

“…The release of surface ions constitutes a valid alternative [6,7,8,9,10]; however, it is not without long-term side e↵ects. A growing volume of literature is instead devoted to investigating the ability of micro and nanoscale textured surfaces to contrast biofilm formation [11,12,13,14,15,16].…”
