DeepARG+ - A Computational Pipeline for the Prediction of Antibiotic Resistance
… categories. Our method takes into account the physio-chemical properties that are intrinsic to different ARG families. Traditionally, new ARGs are predicted by making sequence alignment and calculating sequence similarity to existing ARG reference databases, which can be very time consuming. …

Extrusion and evaluation of degradation rate and porosity of small diameter collagen tubes
… (EDC) and Nhydroxysuccinimide (NHS) to evaluate physio-chemical properties. The samples were also evaluated for their surface area and porosity using mercury porosimeter. The noncrosslinked tubes almost completely degraded after 2 hours. The tubes crosslinked with EDC/NHS degraded slower than the …

The Formation and Characterisation of Protein Bigels
… networks that each contribute to the mechanical properties of the gel producing a much stronger more robust gel. The first protein-protein bigel consisting of BSA and gelatin in a 9:10 ratio, was previously described by my colleagues in 2015 (Blumlein and McManus, 2015). The method of preparation …

Zinc oxide nanowire field effect transistors for sensor applications
A wide variety of tunable physio-chemical properties make ZnO nanowires a promising candidate for functional device applications. Although bottom-up grown nanowires are producible in volume, their high-throughput device integration requires control over dimensions and, more importantly, of precise …
