Figure Lengend Snippet: (A) NO release rates from bare TPU and hydrogel-coated surfaces measured by a Griess-based assay (n = 6). (B) Fluorescence images of platelet adhesion on bare TPU, PDM, PD@Cu, and PDM@Cu surfaces with and without NO donors. (C) Quantification of platelet adhesion by LDH assay (n = 6). (D) SEM images of platelet morphology on bare TPU and hydrogel-coated surfaces. (E) APTT and (F) TT of bare TPU and hydrogel-coated surfaces (n = 3). (G) Digital photographs of thrombus formation on bare TPU and hydrogel-coated surfaces after 5, 10, and 15 min during recalcification assays.

Article Snippet: Cell counting kit-8 (CCK-8), activated partial thromboplastin time (APTT) kit, thrombin time (TT) test kit, and enhanced BCA protein assay kit were obtained from Beyotime Biotechnology Inc., Shanghai, China.

Article Title: Antithrombotic and antibacterial surface coating based on spiky silver nanoparticles: A counterattack against clotting and biofilm

doi: 10.1016/j.mtbio.2026.102762

Figure Lengend Snippet: Anticoagulant performance of surface coatings. (A) Protein adsorption on the surfaces. (B) Platelet adhesion density quantified from (C) fluorescence images of DiOC6-stained platelets. Clotting times determined using (D) APTT and (E) TT assays. Statistical comparisons of samples with PET were performed using a one-way ANOVA test.

Article Snippet: For the APTT assay, 50 μL of PPP was combined with 50 μL of APTT reagent (Dade® Actin FSL, Siemens Healthineers, Erlangen, Germany) and incubated at 37 °C for 30 min.

Techniques: Adsorption, Fluorescence, Staining, Coagulation
