FAQs
How do you apply silver powder?
Silver powder gets used primarily by becoming integrated into conductive pastes for printed electronics, polymer blending for 3D printing filaments, or as a brazing filler material when alloyed. Industrial applications of silver require tight particle size and dispersion process control.
How is silver used as an antibiotic?
Silver is an antimicrobial by ionic disruption - silver ions (Ag⁺) chelate bacterial cell membranes and enzymes, causing structural damage and metabolic interference. Medical applications incorporate silver into wound dressings, catheters, and coatings where prolonged ion release provides prolonged antibacterial activity.
Is silver antifungal?
Yes, silver possesses broad-spectrum antifungal activity. Studies demonstrate activity against Candida, Aspergillus, and other fungi through mechanisms similar to antibacterial activity - cell membrane penetration, ROS production, and inhibition of cellular respiration pathways. Uses for antifungals include surface coatings for medical devices and farm products.
