“…Ideal materials for biosensing need to have several requirements such as good conductivity, biocompatibility, stability in response to changing temperature, ionic strength and pH, selectivity towards analyte of interest, low cost and should be easily mass-produced. 145,146 Metallic and carbon-based nanomaterials, conductive polymers, and metal-organic frameworks have been found to enhance the performance of biosensors and hence have received special attention lately. 34,147 For example, Rahman et al developed a low-potential amperometric glucose sensor by modifying electrodes with multi-walled carbon nanotube film and demonstrated stability for up to 5 weeks with a sensitivity of 12.1 μA/mM.…”

Diabetes leads to chronic microvascular complications for the heart, kidney, and eyes due to uncontrolled glycemic fluctuations. Self-monitoring blood glucose meters can only provide a snapshot of glucose level and are incapable of capturing the granular glucose fluctuations over a 24 hour period. Clinical research has indicated that random blood glucose fluctuations can lead to organ damage. In pursuit of better glucose management, continuous glucose monitoring (CGM) is emerging as a popular alternative owing to its ability to detect instantaneous changes in glucose levels and to alert the users of impending hypo- or hyper-glycemic events. In the last decade, several CGM devices have been launched in the market based on different glucose sensing chemistries and techniques. More research is still needed to come up with novel bio sensing concepts to make CGM low cost and highly accurate. Here, we elaborate the CGM techniques such as electrochemical, optical, reverse iontophoresis, microdialysis, and impedance spectroscopy. We emphasize on the widely used electrochemical CGMs with a focus on sensor design and bio-compatibility. We also provide an outlook for the future technologies, highlighting the need for innovative materials, possibility of integrating with the Internet of Things (IoT) for real-time e-health monitoring.

“…[19][20][21][22] Various nanostructures with novel combinations and topologies have been produced, opening new possibilities for nanomaterial-based sensors. [23][24][25][26][27][28][29][30][31][32][33][34][35][36] Current results strongly imply that carbon nanofibers, 37 and multi-walled carbon nanotubes 19 could be used to determine parabens. Nevertheless, depositing these materials onto the detecting electrodes necessitates either several stages process or the usage of expensive noble metals, resulting in materials with perfect anti-fouling qualities.…”

“…In addition, in term of market analysis, to detect an analyte at a higher temperature, it is necessary to demand micro-heating assemblages, which increase cost money, energy demand, size and decreases its lifetime because of merging of grain boundaries of nanostructures operated at high temperature. 33,34,[38][39][40] Reduced graphene oxide (RGO), on the other hand, is one of the least studied materials for this application such as nanoelectronics, conductive thin films supercapacitors, nanosensors and nanomedicine 41,42 because it possesses extraordinary thermal, mechanical and electrical properties. 43 Poly L-lysine (PoL) possesses a high level of biocompatibility, many active amino groups, a flexible structural framework, and good water solubility.…”

A PoL/RGO material was successfully synthesized and employed to modify the working electrode for determining Methylparaben (MPB) in medication products through voltammetric techniques. The structure of the nanocomposite was characterized by UV-Visible and Fourier transform infrared spectrum and its application to the MPB electrochemical detection was tested by the cyclic voltammetry and DPV techniques. In the result, the modified PoL-RGO/GCE electrode exhibited a superior response toward MPB by applying the DPV method, compares to using the bare GCE, with a limit of detection, a limit of quantification is 0.20 and 0.70 µM, respectively, and the concentration ranging from 1 to 200 µM. In addition, the repeatability (RSD of 2.2, 1.6, 1.4 for 5, 50 and 100 µM MPB, respectively), and the reproducibility (RSD of 4.7%) of the technique were examined as well.

In the present work, twelve inorganic thermoluminescence dosimeteric (TLD) materials doped with some rare earth elements (LiF:Sm, LiBaP2O7:Eu, CaCO3:Eu, CaSO4:Dy, SrSO4:Sm, CdSO4:Dy, BaSO4:Eu, Li2B4O7:Dy, MgB4O7:Gd, Al2O3:Gd, MgAl2O4:Ce, and LiCaAlF6:Eu) and three organic TLD materials (C3H7NO2, C7H8O2 and C4H6BaO4) were selected for comparative analysis on the basis of different photon sensing parameters. About nine photon sensing parameters viz. mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), mean free path (mfp), half value layer (HVL), tenth value layer (TVL), effective atomic number (EAN), effective electron number (EEN), exposure buildup factor (EBF), and energy absorption buildup factor (EABF) were obtained for the selected fifteen TLDs. The simultaneous variation of these photon sensing parameters for the selected TLDs with photon energy and composition has been analyzed. This analysis will help radiation physicists to easily select a particular dosimeter for their research laboratory from different existing compositions. All photon sensing parameters strongly depends upon incident energy and chemical composition in lower and higher energy regions. Among the selected TLDs; BaSO4:Eu3+ offers best results (maximum values for MAC, EAN, EEN; minimum values for TNPs, EBF, EABF); whereas MgB4O7:Gd3+ offers EAN value close to tissue and less variation in sensing parameters with respect to energy.
