Focus Areas in Nano Research (1)
BIO and PHARMA
NANOBIOLOGICAL
PHOTOSYNTHESIS

intended to power a nanomachine
BIOLOGY AND MEDICINE
The biological activity of nanoand nanostructured materials can
be facilitated to make established
treatments more efficient, to find
cures for diseases where there is
no treatment, to remediate
environmental problems, and to
shift frontiers in technological
approaches.
BIOSENSORS

SYNTHESIS
The physical and chemical properties
of nanomaterials are different to those of
the corresponding bulk material. To make
use of this feature, arranging atoms using
chemical and biochemical processes to
form nanomaterials like particles, rods,
wires, tubes, can be performed
applying a multitude of
synthesis methods.
