Abstract

Nanodelivery is a well-known and efficient strategy andherein, we attempted to mimic this strategy using graphene-based nanoscrolls containing metal-organic frameworks (Zn-3(BTC)(2)MOF) for efficient capture of heavy metal ions and inactivate bacterial cells in water. Zn-3(BTC)(2) and graphene scrolls have been used in different fields independently, yet the potential scope of these materials is unexplored. Mimicking metamorphosis of a caterpillar was adapted to design deliverable nanoscroll-encapsulated rod-like Zn-3(BTC)(2)MOF. These constructs lead to targeted inactivation of bacterial cells by puncturing the cells showing a 3 log-fold reduction in E. coli and S. aureus. Additionally, after hydration, the activated porous MOFs result in scavenging heavy metals like lead and arsenic from water sources with a rejection > 99.5%. The uniqueness of these constructs was explored as an easy-to-deploy point of use device (hand-held and in-line kit) for water remediation applications.
