Evaluating the biostability of polypyrrole microwires
The ability to record signals from the brain has wide reaching applications in medicine and the study of the brain. Currently long term neural recording is precluded by the formation of scar tissue around the electrodes inserted into the brain. Conducting polymers present a possible solution to …

Biostability In Drinking Water Distribution Systems Study At Pilot-scale
<p>Biostability and related issues (e.g. nitrification) were investigated for 18 months in 18 pilot distribution systems, under various water quality scenarios. This study specifically investigated the impact of steady-state water changes on HPC levels in chlorinated and chloraminated distribution …

Material selection and manufacture for a polymer heart valve application
… but more insight was required into their biostability. On the other hand, polyurethane-based block copolymers are reputable for their resistance to in vivo degradation, but further study was required to understand their performance in the application. To form a holistic comparison between …

Development of synthetic RNA-targeting catalysts from biostable nucleic acid analogues
… and DNAzyme catalysts in particular—poor biostability and activity on long, structured all-RNA targets under physiological conditions. To explore the possibility of using XNAzymes to specifically target microRNAs and other non-coding RNAs, we retargeted a previously characterised XNAzyme …

Mass spectrometric analysis of chitooligosaccharides and their interaction with proteins
… binding with highest affinity and biostability to HC gp-39. Fluorescence based enzyme assays confirm the results.

Effects of 2015 earthquake on biological stability of water in Nepal
… later. This result indicated the disturbance in biostability of water right after the earthquake and also indicated the recovery of microbiomes with time. In addition, sudden spikes in some bacterial genera associated with opportunistic pathogens were observed after the earthquake, which …

Nitrification Investigation And Modeling In The Chloraminated Drinking Water Distribution System
… nitrite-N in the distribution system. (5) Biostability was assessed for water treatment processes and distribution system pipe by AOCs, BDOCs, and HPCs of the bulk water, and by PEPAs of the attached biofilms. All membrane finished waters were more likely to be biologically stable as …

Encoded synthesis and evolution of clinically approved 2'-modified ribonucleic acids
… high antisense-binding affinity and increased biostability. However, conventional phosphor-amidite synthesis for these 2'-modified nucleic acids is limited in length, prevents parallel exploration of different sequences and modifications, and precludes evolution. This study aims to develop an …

A Novel Biostable 3D Porous Collagen Scaffold for Implantable Biosensor
… nordihydroguaiaretic acid (NDGA) to enhance biostability. NDGA-treated collagen scaffolds were stable without any physical deformation in the subcutaneous tissue of rats for 4 weeks. The scaffold application does not impair the function of our sensor. The effect of the scaffolds on sensor …

A novel polymeric prosthetic heart valve: design, manufacture, and testing
… was evaluated based upon processability, biostability, ex vivo haemocompatibility, and a novel material performance index comprising the flexural modulus and the cyclic fatigue stress predicted by fracture mechanics methods. Polystyrene-block-polyethylene-polypropylene-block-polystyrene …
