Diagnosing and monitoring diseases and health often requires detecting and measuring concentrations of one or more analytes in a patient. Frequent trips to a healthcare facility are onerous and expensive and at home testing is painful, sometimes laborious and time consuming. All of this may lead to a lack of regular testing, and could mean missed diagnoses...

Electrospun Nanoparticle Nanofiber Composites: Porous, Selective, and Stable Background The field of absorption technology spans from the absorption of gas to the absorption of contaminants. However, current absorbing materials are not particularly selective or stable. For an absorbing material to be effective it must minimize the uptake of undesirable...

Smart metal-organic frameworks (MOFs) are porous, crystalline materials made of metals bonded to organic molecules (ligands) that have changeable properties when introduced to external stimuli. Changing the minimum energy required to excite an electron into a conductive state (optical band gap energy) allows control of the conductivity. Most efforts...

Capturing carbon dioxide from open air to minimize harmful emissions becomes less effective with lower carbon dioxide concentration. To address this, scientists use moisture swing sorbents which are chemicals that bind to carbon dioxide in dry environments and release it when exposed to moisture. Metal-organic frameworks (MOFs) contain a metal and a...
