Here, we demonstrate improved NO 2 gas sensing properties based on reduced graphene oxide (rGO) decorated V 2 O 5 thin film. Excluding the DC sputtering grown V 2 O 5 thin film, rGO was spread over V 2 O 5 thin film by the drop cast method. The formation of several p–n heterojunctions was greatly affected by the current–voltage relation of the rGO-decorated V 2 O 5 thin film due to the p-type and n-type nature of rGO and V 2 O 5 , respectively. Initially with rGO decoration on V 2 O 5 thin film, current decreased in comparison to the pristine V 2 O 5 thin film, whereas depositing rGO film on a glass substrate drastically increased current. Among all sensors, only the rGO-decorated V 2 O 5 sensor revealed a maximum NO 2 gas sensing response for 100 ppm at 150 °C, and it achieved an approximately 61% higher response than the V 2 O 5 sensor. The elaborate mechanism for an extremely high sensing response is attributed to the formation and modulation of p–n heterojunctions at the interface of rGO and V 2 O 5 . In addition, the presence of active sites like oxygenous functional groups on the rGO surface enhanced the sensing response. On that account, sensors based on rGO-decorated V 2 O 5 thin film are highly suitable for the purpose of NO 2 gas sensing. They enable the timely detection of the gas, further protecting the ecosystem from its harmful effects.
Facile in situ Electrosynthesis and High Electrocatalytic Performance of Interconnected Layered Double Hydroxides/Graphene Hybrids for Dopamine Oxidation: A Comparative Study

Electroanalysis, 2019
We are reporting a facile in situ electrodeposition approach to prepare a rational design of M−Al (M: Ni, Co) layered double hydroxide (LDH)/reduced graphene oxide (G) hybrids and its superior electrocatalytic activity towards the electrooxidation of dopamine. Comparatively, the worm like interconnected nano‐chain networks of as‐prepared NiAl‐LDH/G hybrid modified electrode exhibits better performance than the CoAl‐LDH/G hybrid modified electrode. The enhanced electrocatalytic activity is because of its morphological evolution, which is due to its enhanced reduction rate, attachment pathway and incorporation or heterogeneous combination of Al3+ in the bimetallic LDHs/G hybrid. The satisfactory results are obtained for modified electrodes for the real‐time quantitative detection of dopamine in the real injectable medicine as well as human blood serum samples and it has also shown good reproducibility, stability and anti‐interference. This cost‐effective and facile in situ electrodeposition approach will give insights to design high performing hybrid materials and its application to non‐invasive electrochemical sensing which will be useful for daily diagnosis of neurological disorder.

Ischemic stroke involves pro-inflammatory species, which implicates inflammation in the disease mechanism. Recent studies indicate that the prevalence of therapeutic choice such as stem cell transplantation has seen an upsurge in ischemic stroke. However, after transplantation the fate of transplanted cells is largely unknown. Human mesenchymal stem cells (MSCs), due to their robust survival rate upon transplantation in brain tissue, are being widely employed to treat ischemic stroke. In the present study, we have evaluated naringenin-loaded gelatin-coated polycaprolactone nanoparticles (nar-gel-c-PCL NPs) to rescue MSCs against oxygen glucose deprived insult. Naringenin, due to its strong anti-inflammatory effects, remains a therapeutic choice in neurological disorders. Though, the low solubility and inefficient delivery remain challenges in using naringenin as a therapeutic drug. The present study showed that inflammation occurred in MSCs during their treatment with oxygen glucose deprivation (OGD) and was well overturned by treatment with nar-gel-c-PCL NPs. In brief, the results indicated that nar-gel-c-PCL NPs were able to protect the loss of cell membrane integrity and restored neuronal morphology. Then nar-gel-c-PCL NPs successfully protected the human MSCs against OGD-induced inflammation as evident by reduced level of pro-inflammatory cytokine (TNF-α, IFN-γ, and IL-1β) and other inflammatory biomarkers (COX2, iNOS, and MPO activity). Therefore, the modulation of inflammation by treatment with nar-gel-c-PCL NPs in MSCs could provide a novel strategy to improve MSC-based therapy, and thus, our nanoformulation may find a wide therapeutic application in ischemic stroke and other neuro-inflammatory diseases.
Elucidation of confined copper nanospheres within self-assembled curcumin-cysteine and their electrocatalytic application

Journal of the Electrochemical Society, 2019
By introducing Cu into the self-assembled curcumin-cysteine on gold electrode, the surface reactivity has been tuned by potentiodynamic electrodeposition approach. The synthesis of curcumin-cysteine has been carried out by modified Fischer esterification method and confirmed by FT-IR, 1H, and 13C NMR spectroscopy, respectively. The self-assembly of curcumin-cysteine on gold electrode has been confirmed by electrochemical techniques like, cyclic voltammetry and electrochemical impedance spectroscopy (EIS). The surface confinement of modular copper nanospheres and its bi-dentate complexation with the diketo moiety of self-assembled curcumin-cysteine is enhancing the catalytic activity. Further, as-constructed electrochemical platform has been exploited for electrocatalytic application like: electroreduction of p-nitrophenol and also tested for real world sample analysis. The fabricated sensor has shown an enhanced sensitivity (i.e, 153.08 μAμM−1cm−2) and low level of detection (i.e, 57 nM) of p-nitrophenol as well as good selectivity in the presence of interfering species. The present investigation is providing an ideal approach for resource limited settings to construct an economically viable sensor and molecular electronic devices.
