Hollow mesoporous carbon nanocarriers for vancomycin delivery: understanding the structure-release relationship for prolonged antibacterial performance.

Mono-dispersed mesoporous hollow carbon (MHC) nanospheres with comparable structures have been designed as nanocarriers for the delivery of vancomycin (Van) to inhibit bacterial growth. It is demonstrated that MHC materials possess a Van loading capacity of 861 mg g, much higher than that of any Van nanocarrier in previous reports. By comparing the drug loading, release and antibacterial performance of MHC nanospheres with controllable structures, it is shown that MHC with a pore size of 5.

Mesoporous Magnesium Oxide Hollow Spheres as Superior Arsenite Adsorbent: Synthesis and Adsorption Behavior.

Arsenic contamination in natural water has posed a significant threat to global health due to its toxicity and carcinogenity. Adsorption technology is an easy and flexible method for arsenic removal with high efficiency. In this Article, we demonstrated the synthesis of mesoporous MgO hollow spheres (MgO-HS) and their application as high performance arsenite (As(III)) adsorbent.

Synthesis of Magnesium Oxide Hierarchical Microspheres: A Dual-Functional Material for Water Remediation.

High concentration of heavy metals and microbes present in water can reduce the quality of water and bring serious side effects to human beings. Their removal from water is of great importance. In this study, MgO microspheres with hierarchical morphology have been synthesized by a facile and low-cost precipitation-aging-calcination method and their dual functionality for effective arsenic removal and microbial inhibition has been investigated for the first time.
