Abstract

We probe the optical properties and intermolecular interactions in magnetically responsive nanoemulsions in the presence of glucose. The equilibrium interdroplet distance between the emulsion droplets in an one-dimensional array increases by several nanometers in the presence of glucose because of intermolecular hydrogen bonding with sodium dodecyl sulphate molecules at the oil-water interface that gives rise to stretched lamellae-like structure. The observed large red shift in the diffracted Bragg peak (∼50–100 nm) and the linear response in the glucose concentration range of 0.25–25 mM offer a simple, fast, and cost effective non-enzymatic approach for glucose detection.

Electrospun porous La–Sr–Co–Ni–O nanofibers for highly sensitive non-enzymatic glucose detection

Journal Article Pelucarte, Kasci; Hatchell, Tashi; George, Gibin; ... - Materials Advances

Glucose biosensors are widely used for clinical, industrial, and environmental applications. Nonenzymatic electrochemical glucose biosensors based on metal oxides with a perovskite structure have exhibited high sensitivity, excellent stability, and cost efficiency. In this work, porous La–Sr–Co–Ni–O (LSCNO) nanofibers, with an ABO₃-type perovskite structure, were prepared through optimizing the A-site and B-site elements by electrospinning, followed with calcination at 700 °C for 5 h. Characterized by scanning and transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy, fabricated nanofibers were confirmed to be porous and nanosized polycrystalline grains with high crystallinity. A novel La_0.75Sr_0.25Co_0.5Ni_0.5O₃-based nonenzymatic electrochemical biosensor was developed, whichmore »« less

Journal Article Jothi, L.; Jayakumar, N.; Jaganathan, S. - Materials Research Bulletin

Highlights: • Nickel nanoparticles incorporated graphene nanosheets/graphene nanoribbons (GS/GNR/Ni) composite was synthesized by in-situ chemical reduction route and the as prepared GS/GNR/Ni modified glassy carbon electrode (GCE) was applied to detect glucose. • The fabricated GS/GNR/Ni/GCE modified electrode exhibits outstanding performance for non-enzymatic glucose sensing with sensitivity (2.3 mA/mM cm{sup 2}), linear range (5 nM - 5 mM) and detection limit (2.5 nM). • GS/GNR/Ni/GCE modified electrode exhibited a high selectivity towards glucose against the interferents, such as ascorbic acid (AA), uric acid (UA), dopamine and sucrose. - Abstract: A fast, highly sensitive and selective non-enzymatic electrochemical glucose sensor basedmore »« less

Non-enzymatic glucose sensor based on electrodeposited copper on carbon paste electrode (Cu/CPE)

Journal Article Wibowo, Rahmat; Fajri, Iqbal - AIP Conference Proceedings

The development of non-enzymatic glucose sensor has much attention due to their applications in glucose monitoring. In this research, copper oxide is used as a non-enzymatic glucose sensor by oxidizing glucose to gluconolactone. Copper was electrodeposited on Carbon paste electrode (CPE) at constant potential. The experimental condition was varied in electrodeposition of Cu with the following parameters: Electrodeposition time 60 s, 120 s and 180 s and potential reduction -0.166 V, -0.266 V and -0.366 V. The effective performance of these working electrodes in sensing glucose was investigated. The Cu/CPE which used -0.366 V potential reduction and 120 s electrodeposition time shows the bestmore »« less

Strongly Chiral Liquid Crystals in Nanoemulsions

Journal Article Yang, Yu; Palacio‐Betancur, Viviana; Wang, Xin; ... - Small

Abstract Liquid crystal (LC) emulsions represent a class of confined soft matter that exhibit exotic internal organizations and size‐dependent properties, including responses to chemical and physical stimuli. Past studies have explored micrometer‐scale LC emulsion droplets but little is known about LC ordering within submicrometer‐sized droplets. This paper reports experiments and simulations that unmask the consequences of confinement in nanoemulsions on strongly chiral LCs that form bulk cholesteric and blue phases (BPs). A method based on light scattering is developed to characterize phase transitions of LCs within the nanodroplets. For droplets with a radius to the pitch ratio ( R _vmore »« less

Irreversible shear-induced vitrification of droplets into elastic nanoemulsions by extreme rupturing

Journal Article Wilking, James; Mason, Thomas - Physical Review. E, Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics

Many materials weaken through fracturing when subjected to extreme stresses. By contrast, we show that breaking down repulsive bits of matter dispersed in a viscous liquid can cause a dramatic and irreversible increase in the dispersion's elasticity. Anionically stabilized microscale emulsions subjected to a history of high-pressure microfluidic flow can develop an unusually large elastic modulus as droplets are ruptured to the nanoscale, yielding 'nanonaise'. As the droplet size approaches the Debye screening length, the nanoemulsion vitrifies. Consequently, the onset of elasticity for disordered uniform nanoemulsions can occur at droplet volume fractions far below maximal random jamming of spheres.
