The separation and removal of oil or organic pollutants from water is highly imperative. phases in surfactant-free oil-in-water emulsions free oil/water mixtures can be smartly enriched transported by using superhydrophobic/superoleophilic iron particles (SHIPs) under a magnetic field. For water-in-oil emulsion, SHIPs-based composite membranes selectively allow the to pass through. Their convenient scalable preparation, excellent performance, good reusability are great advantages for...

The growing trend for personalized medicine calls more reliable implantable biosensors that are capable of continuously monitoring target analytes extended periods (i.e., >30 d). While promising various applications constantly being developed in the laboratories across world, many struggle to maintain functionality complex vivo environments over time.

Nonenzymatic glucose biosensors have the potential for a more reliable in vivo functionality due to reduced risk of biorecognition element degradation. However, these novel sensing mechanisms often are nanoparticle-based and nonlinear responses, which makes it difficult gauge their utility against conventional enzymatic biosensors. Moreover, nonenzymatic suffer from poor selectivity that needs be better addressed before being used vivo. To address problems, here we present an amperometric...
