Vassili Karanassios


Vassili KaranassiosVassili Karanassios' interests are in the area of micro- and nano-analysis (e.g., metrology) and in development of miniaturized instruments that can be used on-site (i.e., in the field).  Such instruments are fabricated on-chips so that they can fit in the palm of a hand or in a shirt pocket, thus allowing users to take “the lab to the sample”. The sample may be a “patient” (for early diagnosis of disease) and the field may be a health clinic or the environment (e.g., the air we breathe or the water we drink).
