Omkar 3 Department of Electronics & Communication Engineering, National Institute of Technology, Warangal, India Department of Electrical & Electronics Engineering, National Institute of Technology, Warangal, India Department of Aerospace Engineering, Indian Institute of Science, Bangalore, India Exposure to radiation, suffering from severe diseases for long periods of time, regular intensive chemotherapy, and mineral deficiency may result in leukopenia, a depleted condition of white blood cells in the human body, depending on their levels of intensity. This elevates the body¡¯s susceptibility to infection. To date, the primary techniques in practice for the short-term treatment of leukopenia are cytokine therapy and steroid administration, each of which causes serious long-term health effects such as hormonal imbalance. This paper aims at the presentation and experimentation of a new technique for the treatment of leukopenia with minimal side effects by devising and using silver composite nanoparticles. This is the first paper to present a safe bio-physical technique using composite nanoparticles for the immediately effective short-term treatment of infection under leukopenia. The increase in efficiency of a blood sample in fighting against pathogenic bacteria cells on application of this technique in vitro is observed through plotted graphical representations of experimental results. http://pubs.sciepub.com/nnr/1/1/2/nnr-1-1-2.pdf white blood cells leukopenia infection short-term treatment composite nanoparticles
