The growing demand for increased fresh food shelf life as well the need of protection against foodborne diseases urged development antimicrobial packaging. Among most efficient methods, combination organic–inorganic, packaging, i.e. polymer embedded metal nanoparticles proved to be highly effective. Silver (AgNPs), in particular, have antimicrobial, anti-fungi, anti-yeasts and anti-viral activities can combined with both non-degradable edible polymers active actual application AgNPs...
Abstract The Nicholson's treatment for the evaluation of heterogeneous standard rate constant k 0 electron transfer from cyclic voltammetric (CV) data is combined with Klingler and Kochi method suitable to totally irreversible systems in order use very large Δ E p x n values, where number electrons involved a simple electron‐transfer process O+ e − ⇌R. An empirical relationship between dimensionless parameter Ψ = [π DnvF/(RT )] −1/2 which practically replaces working curve up about 200 mV reported.
Abstract Here we report the first mediated pain free microneedle‐based biosensor array for continuous and simultaneous monitoring of lactate glucose in artificial interstitial fluid (ISF). The gold surface microneedles has been modified by electrodeposition Au‐multiwalled carbon nanotubes (MWCNTs) successively electropolymerization redox mediator, methylene blue (MB). Functionalization Au‐MWCNTs/polyMB platform with oxidase (LOX) enzyme (working electrode 1) FAD‐Glucose dehydrogenase...
Abstract In this review, we analyze several types of graphene‐based sensors for glucose detection with respect to their preparation, properties and efficiency in electrochemical processes. Graphene may display different defects, which play a role the electron transfer Oxygenated groups on edges graphene planes reduce in‐plane conductivity, but enhance heterogeneous electron/proton constant. Other positive effects defects are related shortening distance between active centers electrodes upon...
In this paper, we present the first highly porous gold (h-PG) microneedles-based second-generation biosensor for minimally invasive monitoring of glucose in artificial interstitial fluid (ISF). A electrode was prepared by a simple electrochemical self-templating method that involves two steps, electrodeposition and hydrogen bubbling at electrode, which were realized applying potential −2 V versus saturated calomel (SCE). The surface microneedles modified immobilization...
Abstract In this paper we report on a facile, cost effective and environmental friendly green synthesis method of gold silver nanoparticles (NPs) by using quercetin as reducing agent. The obtained NPs were characterized transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), dynamic light scattering (DLS) UV‐Vis parameters such pH, ionic strength temperature, effectively affecting shape size NPs, have been carefully studied optimized. results showed that the synthesized...
Efficient direct electron transfer (DET) between a cellobiose dehydrogenase mutant from Corynascus thermophilus (CtCDH C291Y) and novel glassy carbon (GC)-modified electrode, obtained by electrodeposition of gold nanoparticles (AuNPs) was realized. The electrode further modified with mixed self-assembled monolayer 4-aminothiophenol (4-APh) 4-mercaptobenzoic acid (4-MBA), using glutaraldehyde (GA) as cross-linking agent. CtCDH C291Y/GA/4-APh,4-MBA/AuNPs/GC platform showed an apparent...
In this paper we present a new method to electrodeposit highly porous gold (h-PG) onto polycrystalline solid electrode without any template. The electrodeposition is carried out by first cycling the potential between +0.8 and 0 V in 10 mM HAuCl4 with 2.5 M NH4Cl then applying negative for production of hydrogen bubbles at surface. After that modified was characterized sulfuric acid estimate real surface area (Areal) be close 24 cm2, which roughly 300 times higher compared bare electrodes...
Dopamine (DA), epinephrine (EP), and norepinephrine (NEP) are the main catecholamine of clinical interest, as they play crucial roles in regulation nervous cardiovascular systems involved some brain behaviors, such stress, panic, anxiety, depression. Therefore, there is an urgent need for a reliable sensing device able to provide their continuous monitoring minimally invasive manner. In this work, first highly nanoporous gold (h-nPG) microneedle-based sensor presented interstitial fluid...
Abstract A new carbon electrode material, obtained by mixing single wall nanotubes (SWNTs) with a mineral oil binder is studied. Carbon nanotube pastes show the special properties of combined various advantages composite electrodes such as very low capacitance (background current) and possibility an easy preparation, modification renewal. better knowledge characteristics reactions at paste (CNTP) was studying electron transfer rates redox couples under different pretreatment conditions....
