Prof. Jinmyoung Joo wrote a book chapter on Diagnostic and Therapeutic Nanomedicine in Advanced Imaging and Bio Techniques for Convergence Science, as a part of Advances in Experimental Medicine and Biology. This chapter provides in-depth understanding on nanotechnology, particularly in biomedical applications, including general concepts and recent advances of nanomedicine for clinically relevant diagnostics and therapeutics. The contents should be an essential information for graduate students and early stage of researchers.
