Magnetic cores loaded with metallic nanoparticles can be promising nano-carriers for successful drug delivery at infectious sites. We report fabrication, characteristic analysis and in vitro antibacterial performance of nanocomposites comprising of cobalt cores (Co-cores) functionalized with varied concentration of silver nanoparticles (AgNPs). A two-step polyol process synchronized with transmetallation reduction method was used. Co-cores were synthesized by cobalt acetate and decoration of AgNPs was carried out by silver acetate. The density of AgNPs was varied...

Assessing the potential of nutrient deficiency for enhancement of biodiesel production in algal resources

Maria Hasnain, Zainul Abideen, Saud Hashmi, Shagufta Naz & Neelma Munir
Depleting energy sources result in a growing interest in the conversion of microalgal biofuel to improve economic feasibility. Efficient and cost effective biomass conversion to biofuel demands an increase of carbohydrates and lipid accumulation in algal cells. In the present study, it is measured that concomitant nitrogen, phosphorous and, iron deficiency induces significant physiological and biochemical changes in microalgae Oedogonium sp., Ulothrix sp., Cladophora sp. and Spirogyra sp. by using Response surface methodology as the...

Biosynthesis, Characterization and Anti-dengue vector activity of Silver Nanoparticles prepared by Azadirachta indica and Citrullus colocynthis

Shafqat Rasool, Muhammad Akram Raza & Zakia Kanwal
Here, we report biosynthesis of silver nanoparticles (AgNPs) using aqueous extracts of (i) Azadirachta indica leaves and (ii) Citrullus colocynthis fruit and their larvicidal activity against Aedes aegypti. The Uv-Vis spectroscopy absorption peaks occurred in range 412-416 nm for A. indica AgNPs and 416-431nm for C. colocynthis AgNPs indicating the silver nature of prepared colloidal samples. The Scanning electron microscopy examination revealed the spherical morphology of both types of NPs with average size of 17±4...
