Respected Recruitment Team,

Greetings !!!

I am Dr. Mallikarjuna Reddy Kesama, currently working as a post-doctoral researcher in Applied DNA Nano-Engineering Lab, Dept. of Physics, Sungkyunkwan University, South Korea. As I mentioned in the E-mail, my Ph.D. research topic was related to “Characterization of Multifunctional Nanomaterials Embedded DNA Thin Films for Usage in Nanotechnology”. I have a work experience on design, construction of nanostructures based synthetic DNA, and fabrication of salmon DNA thin films with various nanomaterials to study its interactions through physical characterizations. I can synthesis various quantum dots through one-pot and hydrothermal methods, and synthesis of gold nanoparticles through chemical reduction method and other nanomaterials in various techniques. The construction of various shapes (0‒3D) and directional alignment of nanomaterials embedded DNA complexes depends on various methodology. The process of eco-friendly and energy efficient hybrid nanostructures are made of organic and inorganic components are technologically important in material science and engineering as well as biological science.  And I have developed the fascinating methodologies to enhance the DNA functionality with various functional nanomaterials, confirmed by an electrical, optical, magnetic, mechanical, and thermal properties which are helpful for usage in several multidisciplinary areas of research. In view of develop novel devices, bio-photonics, spintronics, optoelectronic, and sensors applications (to name a few Capacitors, photodetectors, triboelectric nanogenerators, LEDs, and memory devices), particularly I introduced the DNA growth on various substrates such as silica, glass, fused silica, quartz, and other various functionalized substrates. And DNA can be used to fabricate in its various forms such as self-supporting flexible thin film by simple solvents evaporation, DNA fiber mats by electrospinning and chemical evaporation, DNA fumes by freeze drying, and DNA carbonization for making porous active materials and all these forms can be functionalized with nanomaterials for better performance of the device. The practical usage of nanomaterials embedded DNA complexes are analyzed through the concentration of morphological, optical, electrical, magnetic, thermal, mechanical properties by using characterization tools such as SEM, TEM, AFM, XRD, XPS, UPS, Absorption, Ellipsometry, CD, FTIR, Raman, Probe-station, SQUID, VSM, TGA, DSC, Nano-indentation etc. 

The outcome of my studies would be helpful in the development of innovative novel practical devices based on cost effective, highly efficient, self-assembly, and environmentally friendly with various functionalized nanomaterials. Overall, I sincerely learned about the project design, construction, or fabrication of samples, conducting various characterizations, and analyzing the results with possible mechanism of behaving results trends. I have published 16 papers which includes functional materials embedded with DNA molecules and some of them are in communication and preparation stage. This structural research experiences will help me to work not only in DNA nanotechnology but also even in other area of fields. It will be additional added advantage and opportunity for me to learn more about other innovative materials leading to device applications. In my first postdoctoral research, I have worked on physical properties of amyloidogenesis related to neurodegenerative disorder and physiological response with an optical and electrical signal. On the other hand, I was also focusing on different forms of novel DNA biopolymer for a device such as supercapacitors, and lasers etc. In my second postdoctoral research, I have worked on cocoon silk fibroin protein and DNA/CTMA-DNA in its various form for usage in energy harvesting devices, broadband photodetector, biocompatible tattoo, and optical contact lenses. In my present, third postdoctoral research, I have been focused various shapes of metals and metal oxide nanomaterials integration of DNA molecular based hybrid flexible, self-supporting thin films and its performance in rollable capacitors and broadband photodetector application.  I am also having an industrial work experience of about 4.7 years as a senior technical officer at Hind High Vacuum Company Pvt. Ltd., (HHV) company, Bangalore, India. Where I have learned deep understanding of vacuum and thin film coaters, thin film preparation techniques and its applications. Please find attached this cover letter and CV for your kind perusal, which contains all the information about my up-to-date progress and experience in the research field and industrial field. I request you to provide me an opportunity to work in your research group. I will be highly obliged if you can consider my request and reply positively.
