In the present study, we have fabricated and studied response of cladding modified fiber optic intrinsic glucose biosensor (FOIGB). The optical fiber was used as a light transforming waveguide and sensing element fabricated over it by applying a thin layer of polymer. The cladding of the sensor was modified with the polyaniline-hydrochloric acid (PANI-HCl) polymer matrix. The PANI-HCl matrix provides an amorphous morphology useful to immobilize glucose oxidase (GOx) biomolecules through cross-linking technique via glutaraldehyde. The present sensor was used to detect the glucose analyte in the solution. In the sensing response study of FOIGB toward glucose, novel modal power distribution (MPD) technique was used. The reaction between GOx and glucose changes the optical properties of prepared FOIGB and hence modify MPD at output as a function of glucose concentration. The nature and surface morphology of PANI-HCl matrix has been studied. © 2016 Author(s).

Flavones and chromanones are known to be biologically important compounds over 4000 chemically unique flavanoids have been identified in plant sources. These low-molecular-weight substances, found in all vascular plants, with an assortment of basic structure of phenyl benzopyrones (phenyl chromones). In the present work 2-hydroxy pyrimidine and 2-mercapto pyrimidine were prepared from phenol i.e. o-chlorophenol as a starting material. The compounds were characterized on the basis of elemental analysis their IR, 1HNMR and screened for their antifungal activity. Some of these compounds showed significant antifungal activity. The activity was correlated with the structure.

Methylene blue adsorption from an aqueous solution on to Ferronia elefuntum fruit shell (FEFS) has been studied experimentally using the batch adsorption method. The operating variables studied are pH, initial dye concentration contact time. Adsorption isotherm (Langmuir and Freundlich) and kinetics model were studied. The adsorption capacity of FEFS was found to increasing with increase in temperature, thermodynamics parameters such as ΔG, ΔH and ΔS for adsorption were evaluated. Adsorption of methylene blue on FEFS found to be endothermic process. The aim of present work is to study the effectiveness of the adsorbent to remove dyes from their aqueous solution and the removal of colour from textile and various industrial wastewater.

In this research work, activated carbon prepared locally from The Commiphora Wightii bark(CWB) was examined for the removal of cobalt (II) from aqueous solution. The main parameters, like effect of adsorbent dosage, Co (II) concentrations, effect of contact time and effect of pH was studied in batch experiments. The experimental results were analyzed by using Langmuir, Freundlich, adsorption isotherm models. The kinetic data well described by the pseudo-first-order kinetic model. The various thermodynamic parameters such as and were also determined. The CWB was successfully employed for removal of cobalt (II) ion from aqueous solution and the technique appears industrially applicable and feasible. © 2013 RASĀYAN. All rights reserved.

Polyaniline (PANI) and its composites have drawn considerable interest because of their economical importance, good environmental stability and satisfactory conductivity among the conductive polymers. Polymers are playing an increasingly important role in the development of biosensors. The use of conducting polymer composites for the construction of biosensor is increasing nowadays for the immobilization of biomolecules as it enhances the activity and performance of the sensor. In the present investigation, we have used PANI-oxalic acid (OA) for the cladding modification to prepare fiber optic intrinsic glucose biosensor (FOIGB) for detection of glucose. PANI-OA composite have shown good binding toward enzyme-glucose oxidase (GOx) and high biological activity that results in enhanced sensing characteristics. This investigation highlights approach to synthesize PANI-OA composite and its applications in cladding modified FOIB technology. The characterizations were made using X-ray diffraction and scanning electron microscopy (SEM) techniques. The results revealed the formation of homogeneous, PANI-OA film on sensing element. The sensing response of FOIGB toward glucose was measured by monitoring variation in power with varying glucose concentration. © 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
