“…In most reports PGEs were used for enzyme-based glucose determination [ 17 ]. For example, more recently PGEs have been used for immobilization of glucose oxidase for glucose biosensing [ 18 , 19 ]. A literature survey revealed that there are no studies to date on the use of copper nanoparticle-modified PGEs for nonenzymatic determination of glucose.…”

A nonenzymatic glucose sensor based on a disposable pencil graphite electrode (PGE) modified by copper nanoparticles [Cu(NP)] was prepared for the first time. The prepared Cu(NP) exhibited an absorption peak centered at ∼562 nm using UV-visible spectrophotometry and an almost homogenous spherical shape by scanning electron microscopy. Cyclic voltammetry of Cu(NP)-PGE showed an adsorption controlled charge transfer process up to 90.0 mVs. The sensor was applied for the determination of glucose using an amperometry technique with a detection limit of [0.44 (±0.01) μM] and concentration sensitivity of [1467.5 (±1.3) μA/mMcm]. The preparation of the Cu(NP)-PGE sensor was reproducible (relative standard deviation = 2.10%, n = 10), very simple, fast, and inexpensive, and the Cu(NP)-PGE is suitable to be used as a disposable glucose sensor.

“…In this case, the porous structure was formed by both leachable salt particles and a polymer-poor phase removing. 18 According to the above discussion on two methods of obtaining PU scaffolds, it is important to note that the particular system of PU needs the proper methodology of bone scaffold fabrication.…”

In this work, a novel polyurethane (PU) system based on poly(ethylene-butylene) adipate diol, 1,6-hexamethylene diisocyanate, 1,4-butanediol, and ascorbic acid was used to prepare scaffolds with potential applications in bone tissue engineering. Two fabrication methods to obtain porous materials were chosen: phase separation (PS)/salt particle leaching (PL) and solvent casting (SC)/salt PL. The calculated porosity demonstrated that scaffolds with a higher porosity were obtained (76–86%) using the PS/PL method. The morphology of pores was examined with the use of optical stereomicroscope and scanning electron microscope. The appropriate porosity, pore morphology, and swelling properties for bone tissue scaffolds were obtained for our novel PU system by the PS/PL method using 15 wt% solution of PU in the mixture of dimethylformamide (DMF)/tetrahydrofuran solvents and by SC/PL method from 20 wt% from DMF. The distilled water and saline water swelling for those samples was also appropriate for bone tissue scaffold application.

“…Active anti-fouling strategies utilize stimuli-responsive materials to reversibly change a material’s properties. Mechanical stress, light, pH, temperature, acoustic waves or electrical/magnetic fields have been used in active anti-fouling sensors [ 83 ] [ 84 ]. Temperature responsive polymers have a volume phase transition temperature (PVTT) property which marks the temperature at which the polymer drastically and discretely changes its physical arrangement.…”
