dear sir/madam,
i am doing my 2nd year m.sc medical bio nanotechnology course in chettinad university,i did my final year project and implimentation on synthesis synthesis and toxicological evaluation of cuo nanoparticles in albino rats.cuo nanoparticles which i synthesized is of 38nm,where i gave this formulation dispersed in tween 20 for 7 days.on 8th day i sacrificed it and did liver function test and lipid profile.then all the vital organs were given for histopathological analysis.
i need to present this work for poster presentation suggest some ideas.

Bionanotechnology is the intersection of biology and nanotechnology. Bionanotechnology may also refer to the use of biomolecules for applications in nanotechnology. A major example of this is DNA nanotechnology, which uses self-assembling nucleic acid structures to control matter at the nanoscale. bionanotechnology refers to synthetic technology based on the principles and chemical pathways of living organisms. It encompasses the study, creation, and illumination of the connections between structural molecular biology and nanotechnology, since the development of nanomachinery might be guided by studying the structure and function of the natural nano-machines found in living cells. The science heavily relies on the characterisation of biological material on surfaces (using e.g. dual polarisation interferometry, AFM, QCMD,Surface Plasmon Resonance). A related field is bionanoscience.
Future bio-nanotechnology will use computer chips inside living cells.Continuing miniaturization has moved the semiconductor industry well into the nano realm with leading chip manufacturers on their way to CMOS using 22nm process technology. With transistors the size of tens of nanometers, researchers have begun to explore the interface of biology and electronics by integrating nanoelectronic components and living cells. While researchers have already experimented with integrating living cells into semiconductor materials (see "Scientists integrate living brain cells into organic semiconductors") other research is exploring the opposite way, i.e. integrating nanoelectronics into living cells.
The study of individual cells is of great importance in biomedicine. Many biological processes incur inside cells and these processes can differ from cell to cell. The development of micro- and nanoscale tools smaller than cells will help in understanding the cellular machinery at the single cell level. All kinds of mechanical, biochemical, electrochemical and thermal processes could be studied using these devices.
A typical human cell is the size of about 10 square micrometers which means that hundreds of today's smallest transistors could fit inside a single cell. If the current rate of miniaturization continues, by 2020 approximately 2.500 transistors – equivalent to microprocessors of the first generation of personal computers – could fit into the area of a typical living cell.
