Biodegradable polymer backbone shapes plastisphere assembly, enhancing antibiotic sorption and reshaping aquatic microbial communities.
Biodegradable plastics are widely considered environmentally safer alternatives to conventional polymers, yet whether plastisphere-mediated aging amplifies or mitigates their antibiotic vector potential remains mechanistically unresolved. Using polylactic acid (PLA) and polybutylene succinate (PBS) microplastics aged i...
