The Impact of Triclosan on the Spread of Antibiotic Resistance in the Environment [PDF]

open access: yes, 2015
Triclosan (TCS) is a commonly used antimicrobial agent that enters wastewater treatment plants (WWTPs) and the environment. An estimated 1.1 × 105 to 4.2 × 105 kg of TCS are discharged from these WWTPs per year in the United States.

Ultrasound‐Assisted for Super‐Rapid and High‐Efficient Adsorption and Desorption

open access: yesAdvanced Science, EarlyView.
Adsorption–desorption technologies face challenges due to slow adsorption and complex regeneration. This study shows that PVDF‐HFP offers exceptional adsorption kinetics and regeneration efficiency under ultrasound, adsorbs Rhodamine B 23,000 times faster than activated carbon, removing 90% of levofloxacin and PFOA in 5 min, and maintains performance ...

Multifunctional Framework Nucleic Acid Vehicle for Antibiotic Sensitization and Treatment of Methicillin‐Resistant Staphylococcus aureus

open access: yesAggregate, EarlyView.
A self‐assembling, aggregation‐enhanced tetrahedral DNA nanostructure (tFNA), termed TACs, enables localized accumulation and sustained release of ceftriaxone while co‐delivering antisense oligonucleotides that silence mecA, reduce PBP2a expression, and restore β‐lactam susceptibility in MRSA.
