Development of Superparamagnetic Iron Oxide Core-shell Nanoparticles and its Applications in Modern Drug Delivery Systems
The focus of my present research project is the functionalization and tailoring of nanoparticle surfaces to perform specific tasks in a biological environment. The particles include superparamagnetic iron oxide nanoparticles, core-shell nanostructures and superparamagnetic iron oxide nanocomposites. The unique nanomaterials have been developed to address continued issues in cancer therapy, including cancer diagnosis and efficient drug delivery. Various characterization tools are being used to study the size distribution, agglomeration, surface texture and magnetic properties of the nanoparticles. For this purpose, the Scanning Electron Microscopy, Transmission Electron Microscopy, Beta Sizer, Atomic Force microscopy and Vibrating Sample Magnetometer are included but not only for characterization. Furthermore, the release of various drugs as a function of time is the important objective to study. The project might be extended to identification and study of the various types of proteins accumulation on different nanoparticle factionalized and nonfunctionalized surfaces.

Graphene/SPION-photocatalytic nanocomposites as nanosorbents for the water and wastewater treatment
I am currently working on the photocatalytic nanocomposites for water and waste water treatment. This project is based upon the development of nanocomposite of graphene oxide with core-shell Fe3O4/ZnO/TiO2nanoparticles as nanosorbents for the removal of toxic ions and bacteria from water and waste water. The nanostructure composite developed for this purpose will consist of a mixture of functionalized graphene oxide and core-shell nanoparticles of Fe2O3/ZnO/TiO2. In the past years it has been shown that graphene has a very high electrical conductivity of electron knows as ballistic behavior. Combination of this character with being hydrophilic in nature, will provide higher efficiency of the water purification process. The Fe3O4, TiO2 and ZnO photocatalysts act as nanosorbents in UV-vis light and attract all the micro level impurities such as metal ions (e.g. Pb+2 and Cr+6) and dissolved minerals with chloride and sulfate ions. This nanocomposite is expected to be an excellent contribution in the field of water purification and separation.
Additive manufacturing and characterization of stainless stell and titanium based alloys for biomedical applications
Exciting and challenging materials demand new manufacturing techniques. 3D printing goes beyond all limits challenged by conventional manufacturing methods. The motive of my research project is to 3D print stainless steel and titanium based complex structures with Reinshaw AM250 printer for biomedical applications such as bone scaffolds and dental implants. To treat the skeletal fractures and to replace small portion of bones, bone scaffolds are in use as an alternative to natural bone. An ideal bone scaffold material must meet the bio functionaland structural properties of natural bone. After printing the required material, mechanical and electrochemical behavior are being analyzed. Another challenge of these scaffolds is to favor cell growth on its surface. My sole purpose is to mitigate these challenges. This work will include printing such structures, favor their enhanced mechanical properties, electrochemical behavior and provide all necessary environments for the material to stay in body without causing infections.
The focus of our project is to produce metallic glasses using the combination of different quintessential novel materials by magnetron sputtering. After the production of TFMG the research work can be divided into three parts. The first part is the basic characterization techniques which are implied to evaluate different intrinsic properties (Glass forming ability, Nature of the film etc.) of the produced metallic glass. The goal of producing such metallic glass is to make them use in the medical sector. For being a metallic glass biocompatible the two important properties I am highly interested in are 1. The electrochemical behavior and 2. Durability of the TFMG inside the body. Thus each TFMG are characterized on the basis of its performance in the required electrolytes and the mechanical properties are evaluated accordingly which is the second part of my work. Studying the biocompatibility of the TFMGs with respect to biological cells or culture is the third and final part of my research.
Combinatorial development of bulk metallic glasses with potential applications for next-generation intracoronary drug-eluting stents
The focus of this project is to fabricate a quintessential novel biomaterial for new-generation intracoronary drug-eluting stents. Amorphous multicomponent thin films will be developed using RF/DC Magnetron co-sputtering. Compositional libraries will be synthesized through the variation of sputtering parameters and each composition will be extensively characterized to choose a system having incredible combination of biocorrosion resistance, biocompatibility, polymer-like formability and other mechanical properties desired for bioimplants. The chosen system will be both nanoimprinted and dealloyed via selective leaching for drug delivery purposes. Using a model drug, the drug-release-kinetics will be optimized via channelling the multiscale nanopatterns and induced nanoporosity.

Microstructural and Electrochemical Investigation of 3D Printed Stainless Steel
I am currently working on the investigation of electrochemical and microstructural behavior of 3-D printed stainless steel. This project aims to investigate the electrochemical behavior of 3-D printed stainless steel as there is no literature available on this topic yet, As 3-D printing of metals is a recent trend in the modern world due to the fact of cost reduction, less energy consumption, design effective and mass production associated to it. This project is based on the electrochemical study of 3-D printed stainless steel in different electrolytes based on varying pH level and different concentration of Chloride ions in De-Ionized water. This electrochemical data of 3-D printed stainless steel will help to formulate an iso-Corrosion diagram for this system.
