Abstract:
Spectrophotometry is an attractive method for PKa determination in very diluted aqueous solution about 10^-5 to 10^-6M provided that the compound possesses P^H dependent light absorption due to the presence of a chromospheres in proximity to the ionization centers. Traditionally 6 to 8 aliquot solutions of samples in identical concentrations but with different P^H values are prepared & their absorption spectra are registered at single wavelength. This series of solutions can be generated by either preparing the sample in buffer solutions of known P^H or titrating the sample solution e.g. alkalimetry. Then half the absorbance of maximum plotted on graph & interpolated on x-axis that will give value of P^H is Pka & negative Antilog of that value at base 10 give value of ka i.e. Dissociation Constant (Pka=-logka). This exercise is carrying out in below assignment.

Abstract:
Microspheres are solid spherical particles containing a dispersed drug in organic solution fall in a range of 1-1000mm. Microspheres or micro particles are monolithinic device refer to a rate controlling matrix throughout the drug is dissolved or dispersed, while microcapsules are device which consists of cell-like dosage forms with the drug contain within the rate controlling membrane. Microspheres are prepared by several methods. Here Microspheres are prepared using a surface active agent SLS. Then Evaluation of Microspheres is carried out by means of several parameters. Then concluded that the diclofenac: polymer ratio of 1:2 & organic solvent (MeOH: DCM) ratio of 1:4 was found to be optimum for spherical shape of microspheres as well as Practical Yield.

ABSTRACT
Acyclovir is an Anti-viral drug, widely used in the treatment of Ocular herpes simplex. Ophthalmic insert of acyclovir formulated using Methyl cellulose (MC A4CP), polyvinylpyrrolidone (PVP K30) and polyvinyl alcohol as polymers and glycerin use as plasticizer by solvent casting method with aim of increasing the contact time, achieving sustained release drug. The prepared ophthalmic insert were evaluated for uniformity of thickness, weight uniformity, drug content, % moisture absorption, % moisture loss, folding endurance and surface pH. In vitro drug release of formulated batches was performed using Modified Franz Diffusion cell. A 3² full factorial design was applied to systematically optimize the ocular insert. FTIR spectroscopy was performed to study the drug interaction effect in formulation using KBr disc method. On the basis of all physicochemical parameters and in vitro drug release studies, and overall Desirability, the formulation (F8) was found to vary significantly depending on the type of polymers used and their combinations and it was selected for sterility, stability, ocular irritancy study. The result of invitro diffusion study of formulation exhibited non-fickian in nature. From stability studies inserts were remained stable both physically and chemically. The formulation was found to be practically nonirritant in ocular irritation studies using hen's egg chorioallantoic membrane.

ABSTRACT
A biosensor is a device for the detection of an analyte that combines a biological component with physicochemical detector components. An integrated device consisting of a biological recognition element & a transducer capable of detecting the biological reaction & converting it into a signal which can be processed. Ideally, the sensor shod be self-contained, so that it is not necessary to add reagents to the sample matrix to obtain the desired response. There are a number of analytes which are measured in biological media: pH, partial pressure of carbon dioxide, partial pressure of oxygen & the ionic concentration of sodium, potassium, calcium & chloride. Biosensors are typically classified by the type of recognition element or transduction element employed. Sensors might be described as a catalytic biosensor if it is recognition element comprised an enzyme or series of enzymes, a living tissue slice, or whole cells derived from microorganisms such as bacteria, fungi, or yeast. The sensor might be described as a bioaffinity sensor if the basis of operation were a biospecific complex formation. Accordingly, the reaction of an antibody with an antigen or hapten, or the reaction of an ageist or antagonist with a receptor, could be employed. In the former case, the sensor might be called an immunosensor. Since, enzyme-based sensor measure the rate of the enzyme-catalyzed reaction as the basis for their response, any physical measurement which yield a quantity related to this rate can be used for detection. The enzyme may be immobilized on the end of an optical fiber, & the spectroscopic properties related to the disappearance of the reactants or appearance of products of the reaction can be measured. Since biochemical reaction can be either endothermic or exothermic. Miniaturized thermistor based calorimeter called thermistos, have been developed & widely applied, especially for bioprocess monitoring.

ABSTRACT
Pioglitazone HCl is used for the management of type-2 diabetes. It is an absorption window limited drug, whose solubility decreases with increase in the pH and has a short half life of 3-7 h. Here an attempt is made to developed the floating matrix tablets, which design in way that after oral administration the GI resistant time is prolonged and thus to give sustained action with increase in the bioavailability of the drug. Pioglitazone HCl showed maximum absorption at wavelength 269 nm in 0.1N HCl. various formulations were developed by using release rate controlling and gel forming polymers like HPMC, and Carbopol-934 in single and combinations by direct compression method with the incorporation of sodium bicarbonate as gas generating agent. The prepared tablets were characteristics by drug content, floating property, swelling and in vitro dissolution test using USP dissolution test apparatus Type – II (paddle method) in dissolution medium of 0.1 N HCl. The in vitro dissolution results of all tablets were computed by using dissolution software. The prepared tablets were found to be good hardness, diameter, weight variation, thickness, friability drug content, floating property and in vitro drug release. Drug-polymer compatibility studies by FTIR gave conformation about drug purity and showed no interaction between drug and selected polymers. All the formulations had floating lag time below 3 minutes and constantly floated on dissolution medium for more than 12 h. Swelling studies indicated significant water uptake and contributed in drug release. From among all the developed formulations, as F7 prolonged the drug release (95.45 %) for longer period of time (12 hrs.); they were selected as best formulations. The best formulations were found to be stable during stability studies for two months. Thus, selected formulations satisfied floating time, swelling index and in vitro drug release profile requirements for a floating drug delivery system.Tablets of Pioglitazone HCl prepared with HPMC K4M, HPMC K100M and Carbopol 934P were found to be acceptable floating property, water uptake and in vitro drug release.

Abstract :
The potential of Cosmarium species, belonging to green Micro algae, was investigated as a viable biomaterial for biological treatment of triphenylmethane dye, Malachite Green (MG). This can be used for the bioremediation of dye effluents. The results obtained from the batch experiments revealed the ability of algal species in removing dye. The effects of operational parameters (temperature, pH, dye concentration and algal concentration) on decolorization were examined. The stability and efficiency of the algae in long-term repetitive operations were also examined. Michaelis–Menten kinetics was used to describe the apparent correlation between the decolorization rate and the dye concentration.
