## Description

- description: Non-sticking millimetric droplets wrapped with micron/submicron-sized
    liquid repellent solid particles and aggregates are recognized as liquid marbles
    (LMs). LM behaves like a non-wetting solid which enables zeroloss transportation
    on solid surface and liquid pool. The challenge is controlling the liquid-releasing
    behavior, especially on the liquid pool. For example, releasing the inner liquid
    of LM at a specified time in adaptation to the liquid pool condition has not been
    achieved. In the past, different approaches were introduced to demonstrate instant
    release of inner liquid in presence of a specific stimulus—but the report on controlling
    the lifetime of floating LMs in presence of a stimulus is extremely rare in the
    literature. In this context, an inherently porous and crystalline nanomaterial,
    i.e., metal organic framework (MOF) is rationally transformed into a readily chemically
    reactive nanomaterial for associating both a) dual pH-responsive hydrophobicity
    and b) non-responsive superhydrophobicity through a 1,4-conjugate addition reaction.
    Further, the Kang-Jacobi wettability model was applied to examine the wettability
    transition of modified MOFs at various pH. The hydrophobic MOFs yielded LMs with
    the ability to automatically release inner liquid at a pre-defined time without
    requiring external intervention. Furthermore, the strategic association of protonizable
    amine, labile coordination bond and tailored hydrophobicity attributed to dual
    (acidic/alkaline) stimuli responsive adjustable life time of LMs on water pool.
    Such LMs were utilized for demonstrating 1) adjustable drug-release, 2) on-demand
    release of reactants to perform chemical reactions and 3) rapid optode detection
    of NO2 - .
