A porous material that is both hydrophobic and fouling-resistant needed in many applications, such as water purification by membrane distillation. In this work, we take a novel approach to fabricating membranes. Using the zwitterionic amphiphilic copolymer poly(trifluoroethyl methacrylate-random-sulfobetaine methacrylate), electrospin nonwoven, membranes combine high hydrophobicity with resistance protein adsorption. By changing electrospinning parameters solution composition, can be...

Abstract Saliva has significant advantages as a test medium for detection of SARS-CoV-2 infection in patients, such ease collection, minimal requirement supplies and trained personnel, safety. Comprehensive validation large cohort prospectively collected specimens with unknown status should be performed to evaluate the potential limitations saliva-based testing. We developed testing pipeline nucleic acids using real-time reverse transcription PCR (RT-PCR) droplet digital (ddPCR) readouts,...

We report on controlling the optoelectronic properties of self-assembled intercalating compound graphene oxide (GO) and HCl doped polyaniline (PANI). Optical emission X-ray diffraction studies revealed a secondary doping phenomenon PANI with –OH –COOH groups GO, which essentially arbitrate intercalation. A control polarity magnitude photoresponse (PR) is harnessed by manipulating weight ratios to GO (viz., 1:1.5 1:2.2 are abbreviated as PG1.5 PG2.2, respectively), where ±PR = 100(RDark –...
