Summary: In this study, the stability and antibacterial activity of silver nanoparticles (AgNPs) coated with different stabilizers were investigated. The AgNPs showed differences in stability and size change depending on the coating agent used. The stabilizer may function as a growth controller of the nanoparticles, affecting their biological properties. The protective or stabilizing agents also played a role in the antibacterial capacity and stability of AgNPs over time.

Summary: Aging population has increased the demand for orthopedic implants. However, biofilm formation on implants due to antibiotic insensitivity and antimicrobial resistance has been a major challenge. In this study, an antibacterial polypeptide coating was developed to prevent biofilm formation and acquired antibiotic resistance. The coating demonstrated excellent in vivo adhesive capacity and strong antibacterial activity. It also inhibited the expression of genes associated with antimicrobial resistance. In vivo experiments confirmed the effectiveness of the coating in preventing biofilm formation and infections. Overall, this study provides a simple method for preparing antibacterial orthopedic implants without inducing antimicrobial resistance.

Summary: A novel sponge-like polymer-based absorbent (poly(amic acid), PAA sponge) was prepared using a straightforward polymer self-assembly strategy for the efficient removal of lead (II) (Pb(II)) from water. The PAA sponge exhibited a rapid adsorption process with a removal efficiency of up to 89.0% in 2 minutes. The adsorption capacity of the PAA sponge increased with the concentration of Pb(II), reaching a maximum adsorption capacity of 609.7 mg g(-1) according to Langmuir simulation fitting. Additionally, the PAA sponge showed efficient recyclability with a removal efficiency of Pb(II) as high as 93% after five adsorption-desorption cycles.
