Formaldehyde is a carcinogenic indoor air pollutant emitted from wood-based furniture, building materials, paints and textiles. Yet, no low-cost sensor exists for on-site monitoring to fulfill stringent current upcoming (e.g., 8 parts-per-billion by volume, ppb, in France 2023) exposure guidelines. Here, we present an inexpensive handheld formaldehyde detector with proven performance real air. Selectivity achieved compact packed bed column of nanoporous polymer sorbent that separates...
Biopharmaceuticals, including proteins and peptides, have revolutionized the treatment of a wide range diseases, from diabetes cardiovascular disorders to virus infections cancer. Despite their efficacy, most these macromolecular drugs require parenteral administration because high molecular weight relative instability. Over past 40 years, only few oral peptide entered clinical trials, even when formulated with substantial amounts permeation enhancers. To overcome epithelial barrier, devices...
Peptides represent a rapidly expanding class of drugs with broad therapeutic potential. However, due to their large molecular weight and susceptibility degradation in the gastrointestinal tract, most peptide are administered via subcutaneous (SC) injections. Despite extensive research, painless delivery platform for these is still lacking. Recently, an octopus-inspired buccal patch has shown promise addressing this challenge by leveraging synergistic combination mechanical stretching...
Nitrogen dioxide (NO2) is a major air pollutant resulting in respiratory problems, from wheezing, coughing, to even asthma. Low-cost sensors based on WO3 nanoparticles are promising due their distinct selectivity detect NO2 at the ppb level. Here, we revealed that controlling thickness of highly porous (97%) films between 0.5 and 12.3 μm altered sensitivity by more than an order magnitude. Therefore, (20 nm diameter N2 adsorption) with mixed γ- ε-phase were deposited single-step flame spray...
Abstract The buccal mucosa is a highly interesting site for non-invasive drug delivery due to its relatively permeable epithelium and good accessibility. Recently, device-based systems have enabled the of macromolecular drugs by leveraging mechanical stretching forces on tissue assist diffusion. Despite successful exploitation route with such systems, biomechanics are still poorly characterized understood lack adequate characterization methods. Therefore, we propose combination physiological...
Introduction Formaldehyde is a carcinogenic indoor air pollutant emitted from wood-based furniture, building materials, paints and textiles.[1] Yet, no low-cost sensor exists for on-site monitoring to fulfill stringent current upcoming (e.g., 8 parts-per-billion by volume, ppb, in France 2023) exposure guidelines. Here, we present an inexpensive handheld formaldehyde detector with proven performance real air. Selectivity achieved compact packed bed column of nanoporous polymer sorbent that...
Exhaled isoprene could enable non-invasive real-time monitoring of cholesterol-lowering therapies.Here, we report an isoprene-selective sensor at high relative humidity (RH).It is made nanostructured, chemo-resistive Ti-doped ZnO nanoparticles produced by flame spray pyrolysis (FSP) and directly deposited onto substrates forming highly porous films.The constituent particles consist stable solid solutions for Ti levels up to 10 mol%.Ti doping strongly enhance the sensitivity (>15 times higher...
