“…The development of a successful MMM with the desired properties depends on the proper selection of the polymer and filler materials, their structural and physiochemical properties, and the ratios of their concentrations [3]. A favourable base polymer that is commonly used for developing MMMs for gas separation is PDMS [20][21][22]. PDMS has been widely used for MMM applications due to its ideal properties, which include low cost, biocompatibility, nontoxicity, and ease of fabrication [20][21][22][23][24][25][26].…”

Polydimethylsiloxane (PDMS) composites with different weight amounts of multi-walled carbon nanotubes (MWCNT) were synthesised as membranes to evaluate their gas separation properties. The selectivity of the membranes was investigated for the separation of H 2 from CH 4 gas species. Membranes with MWCNT concentrations of 1% increased the selectivity to H 2 gas by 94.8%. Furthermore, CH 4 permeation was almost totally blocked through membranes with MWCNT concentrations greater than 5%. Vibrational spectroscopy and Xray photoelectron spectroscopy techniques revealed that upon the incorporation of MWCNT a decrease in the number of available Si-CH 3 and Si-O bonds as well as an increase in the formation of Si-C bonds occurred that initiated the reduction in CH 4 permeation. As a result, the developed membranes can be an efficient and low cost solution for separating H 2 from larger gas molecules such as CH 4 .

“…Numerous Pt-based microelectrodes, ultra-microelectrodes, or arrays of microelectrodes have been employed for the detection of NO of interest in biological tissues or cell lines, due to the high rate of mass transfer, rapid electrochemical kinetics, diminutive capacitance, fast charging current decay, excellent signal/noise ratios, and overall reduced dimensions of the electrochemical setup [31,44,51,52,53]. Several investigations have already demonstrated the sensing of NO generated from single neurons in pond snails, and human umbilical vein endothelial cells employing microsensors [54,55].…”

The extensive physiological and regulatory roles of nitric oxide (NO) have spurred the development of NO sensors, which are of critical importance in neuroscience and various medical applications. The development of electrochemical NO sensors is of significant importance, and has garnered a tremendous amount of attention due to their high sensitivity and selectivity, rapid response, low cost, miniaturization, and the possibility of real-time monitoring. Nanostructured platinum (Pt)-based materials have attracted considerable interest regarding their use in the design of electrochemical sensors for the detection of NO, due to their unique properties and the potential for new and innovative applications. This review focuses primarily on advances and insights into the utilization of nanostructured Pt-based electrode materials, such as nanoporous Pt, Pt and PtAu nanoparticles, PtAu nanoparticle/reduced graphene oxide (rGO), and PtW nanoparticle/rGO-ionic liquid (IL) nanocomposites, for the detection of NO. The design, fabrication, characterization, and integration of electrochemical NO sensing performance, selectivity, and durability are addressed. The attractive electrochemical properties of Pt-based nanomaterials have great potential for increasing the competitiveness of these new sensors and open up new opportunities in the creation of novel NO-sensing technologies for biological and medical applications.

“…In this regard, particular attention attracts selective identification of various bioanalytes (chemical biomarkers) in human biological fluids and tissues; biosensors are the most effective devices applied for this purpose. Among the many different types of biosensors, electrochemical biosensors are the most distinguished exhibiting low cost, rapid analysis and simple sample preparation [ 3 , 4 , 5 ]. These devices are useful in sensing of such analytes as folic acid [ 6 ], DNA [ 7 ], D- and L-amino acids [ 8 ], uric acid [ 9 ], choline [ 10 ], many cancer biomarkers, e.g., cancer-embryonic antigen [ 11 ], glucose [ 12 ], hydrogen peroxide [ 13 ] and others.…”

Copper and Nickel Microsensors Produced by Selective Laser Reductive Sintering for Non-Enzymatic Glucose Detection

et al. 2021

View full text Add to dashboard Cite

In this work, the method of selective laser reductive sintering was used to fabricate the sensor-active copper and nickel microstructures on the surface of glass-ceramics suitable for non-enzymatic detection of glucose. The calculated sensitivities for these microsensors are 1110 and 2080 μA mM−1·cm−2 for copper and nickel, respectively. Linear regime of enzymeless glucose sensing is provided between 0.003 and 3 mM for copper and between 0.01 and 3 mM for nickel. Limits of glucose detection for these manufactured micropatterns are equal to 0.91 and 2.1 µM for copper and nickel, respectively. In addition, the fabricated materials demonstrate rather good selectivity, long-term stability and reproducibility.
