Improvement of TiN coating on comprehensive performance of NiTi alloy braided vascular stent

Preparation and characterization of polydopamine and n-butyl methacrylate copolymer coatings on titanium–nickel alloy stents

“…The cell proliferation rates for all samples exceeded 110%, indicating robust and healthy cell growth. 30 In conclusion, the surface of NiTi alloy modied by PDA and PBMA-b-PVP-2 shows no cytotoxicity and good biosafety.…”

“…The testing system was immersed in a water bath at 37 °C, and the PBS solutions was used to simulate the body uid. The potential polarization curve was obtained at a scanning rate of 5 mV s −1 within a scan range from −0.6 V to 1.5 V. 30…”

“…Subsequently, 50 mL of the Cell Counting Kit-8 (CCK-8) solution was introduced to each well, followed by further incubation for 2 h. Cell viability was assessed by precisely measuring the absorbance at a wavelength of 450 nm using a microplate reader. 30 3 Results and discussion 1. In Fig.…”

Surface engineering of pure magnesium in medical implant applications

“…Recent investigations into metal biomaterials have progressively shifted their focus towards innovative reconstructive procedures for hard tissues and organs. Examples include the application of nickel-titanium (NiTi) shape memory alloy in vascular stents and [ [4] , [5] , [6] , [7] , [8] ], and the exploration of novel magnesium (Mg)-based alloys for advancements in bone tissue engineering and regeneration [ [9] , [10] , [11] , [12] , [13] , [14] ]. The design and selection of metallic implants depend on their specific medical applications.…”
