Abstract:Over the last few years,bio-nano-material science has emerged as a new exciting field in which theoretical and experimental studies of bio-nano-materials have become a focus,and the importance of nucleic acids and protein as bio-nano-materials to the fundamental development in biology and nanomaterials has begun to be recognized.In particular,biochemistry,biophysics,biomechanics,thermodynamics and electronic magneticpro perties of nucleic acids and proteins as well as intelligent composite biological materials have become a new interdisciplinary frontier in life science and material science.There is an increasing need for a more systematic study of the basic issues involved in bio-nano-materials.Great advances have been made in nano-biochip materials,nanoscale biomimetic materials,nano-motor,nano-composite materials,interface biomaterials,nano-biosensor and nano-drug delivery systems.Here we review the main advances in this field and explore the application prospects.
