3D-flower-like porous neodymium molybdate nanostructure for trace level detection of organophosphorus pesticide in food samples.

Herein we report (i) designing of porous 3D flower-like neodymium molybdate nanosheets (pf-NdM NSs) and (ii) attaining reasonable selectivity towards methyl parathion (MP, organophosphate pesticide) in the presence of structurally comparable interferents. Herein the pf-NdM NSs as a catalyst for electrochemical detection of MP in food samples is reported for the first time. Because of porous morphology, and high surface area, the proposed catalyst offers a high electrocatalytic activity toward MP reduction.

In situ formation of CoO nanoparticles embedded N-doped porous carbon nanocomposite: a robust material for electrocatalytic detection of anticancer drug flutamide and supercapacitor application.

The one-step synthesis of heteroatom-doped porous carbons is reported with the in situ formation of cobalt oxide nanoparticles for dual electrochemical applications (i.e., electrochemical sensor and supercapacitor).

Colorimetric and fluorescence sensing of Zn ion and its bio-imaging applications based on macrocyclic "tet a" derivative.

We report on the synthesis and characterization of trans N, N'-di-substituted macrocyclic "tet a" probe (L) for metal ion sensing. Both the colorimetric and fluorescent titration studies are performed with different metal ions. The results have suggested that the probe L is very selective and sensitive towards Zn ions with significant changes in color.

Theoretical study on cyclophane amide molecular receptors and its complexation behavior with TCNQ.

Complexation behavior of cyclophane amide molecular receptors towards 7,7,8,8-tetracyanoquinodimethane (TCNQ) studied. TD-B3LYP/6-31 + G(d,p) based density functional theory was employed to investigate the photophysical characteristics of the complexes obtained. Syn isomers of cyclophane amide molecular hosts show preferred conformation over other conformations.

Macrocyclic "tet a" derived colorimetric sensor for the detection of mercury cations and hydrogen sulphate anions and its bio-imaging in living cells.

A mono-N-substituted probe L containing a bromosalicylaldehyde pendant arm attached to a tetraazamacrocyclic "tet a" moiety was synthesized via straight forward reaction. The probe L crystallizes in a monoclinic P2/n space group. The probe L displayed quick sensitivity and selectivity towards Hg ions due to its hopeful Chelation Enhancement Quenching (CHEQ) feature.

Nitrogen-doped carbon quantum dots embedded CoO with multiwall carbon nanotubes: An efficient probe for the simultaneous determination of anticancer and antibiotic drugs.

The simultaneous determination of anticancer and antibiotic drugs in biological samples with fast and sensitive methods is an essential task for the effective monitoring of drug therapy. A novel electrochemical sensor for the simultaneous determination of anticancer drug Flutamide (FLU) and antibiotic drug Nitrofurantoin (NF) was developed based on the glassy carbon electrode (GCE) modified with N-CQD@CoO/MWCNTs hybrid nanocomposite. The electro-kinetics of the developed sensor was studied using cyclic voltammetry (CV).

Effect of substitution on the excited state photophysical and spectral properties of boron difluoride curcumin complex dye and their derivatives: A time dependent-DFT study.

The optical, charge transport and electronic properties of boron difluoride curcumin (BFC) complex have been explored using the DFT (Density Functional Theory) method and B3LYP functional with the combination of 6-31 + G(d,p) as a basis set. The influence of substitution with various electron releasing and withdrawing groups on the above properties is analyzed and discussed in this work. The results reveal that the BFC complex on additional electron releasing substitution experiences redshifts in the optical transitions, and this is correlated with the dipole moment, NBO charges, HOMO-LUMO energy gap.

Electrochemical synthesis of nitrogen-doped carbon quantum dots decorated copper oxide for the sensitive and selective detection of non-steroidal anti-inflammatory drug in berries.

We report a sensitive non-steroidal anti-inflammatory drug aspirin (ASA) sensor studies using the nitrogen-doped carbon quantum dots (N-CQD) decorated copper oxide (CuO). A simplistic approach of electrochemical deposition method has been used to prepare the N-CQD incorporated with copper oxide (N-CQD/CuO) and the resulting composite has characterized by analytical techniques. Modified glassy carbon electrode of N-CQD/CuO/GCE is developed and is used for the sensor studies of aspirin.
