Nanoparticles Study Achieves Durably Antibacterial Function

Strategic Insights -

Researchers from Zhejiang Science Technical University have successfully created a method to achieve a durably antibacterial function by immobilizing silver nanoparticles on cotton textiles. By grafting oligomeric polyacrylic acid (PAA) onto cotton fiber surfaces, the team prepared silver nanoparticles with controllable size, which resulted in a desirable antibacterial durability. The antibacterial effect remained over 90% even after 50 laundering cycles. This breakthrough has significant implications for maintaining the safety of human skin and has been recognized for its reliability and effectiveness.
