Facile fabrication of a flexible laser induced gold nanoparticle/chitosan/ porous graphene electrode for uric acid detection

Laser-induced fabrication of gold nanoparticles onto paper substrates and their application on paper-based electroanalytical devices

“…Post fabrication surface treatment is a strategy to increase the electrochemical performance of electrodes and can help to increase fabrication reproducibility by pushing the device's performance towards mass transport limited conditions [10,15]. Gold nanoparticles (AuNPs) are often used for modifying electrochemical sensors due to their electrocatalytic activity towards organic compounds, large surface area, and long-term stability [16,17].…”

“…10,15 Gold nanoparticles (AuNPs) are often used for modifying electrochemical sensors due to their electrocatalytic activity towards organic compounds, large surface area, and longterm stability. 16,17 Hybrid materials incorporating nanoparticles in laser-scribed graphitic surfaces have demonstrated synergistic effects with improved electrochemical performance compared to individual materials. 16,[18][19][20][21][22] Most of these hybrid materials use polyimides as substrates where AuNPs are formed, and no reports were found using paper as a substrate.…”

Here, we describe the fabrication of ePADs with laser-scribed electrodes, modified with AuNPs using paper as a substrate.…”

A Novel Turn-On Fluorescence Probe Based on Cu(II) Functionalized Metal–Organic Frameworks for Visual Detection of Uric Acid

“…Therefore, the sensitive and precise determination of UA is significant in, for instance, disease screening and physiological studies [ 5 ]. In recent years, many methods have been developed for the estimation and detection of UA levels, such as enzymatic assays [ 6 , 7 ], electrochemical sensors [ 8 , 9 , 10 , 11 ], spectrophotometric methods [ 12 , 13 , 14 , 15 ], Raman spectroscopy [ 16 ], chromatography [ 17 , 18 , 19 ], and fluorescent spectrometry [ 20 , 21 , 22 , 23 , 24 ]. Although enzymatic assays are the conventional method for the detection of UA, this method has challenges, including the high purification costs and the thermal instability of enzyme.…”

Sodium alginate and Chitosan aided design of form-stable Polyrotaxane based phase change materials with ultra-high latent heat

“…(Liu et al, 2022, Kurnia et al, 2022 A typical shape-stable PCM consists of a 3D skeleton and a PCM work substance. , Xue et al, 2019 For the 3D skeleton part, more and more scientists have tried various green substrates (such as, Chitosan (CH), (Du et al, 2022, Samoson et al, 2022 Cellulose and sodium alginate (SA) ) to prepare 3D-foam for the PCM substance encapsulation. For example, Jia et al fabricated boron nitride (BN)@chitosan (CH) frameworks with three-dimensional (3D) porous structures were fabricated, and effective thermal conductive pathways could be created in the resultant porous materials for PCM encapsulation.…”
