Paper Abstract
A new way of developing optical nanosensors is presented. Organic
nanofibers serve as key elements in these new types of devices,
which exploit both the smallness and brightness of the
nanoaggregates to make new compact and sensitive optical
nanosensors. On the basis of bottom up technology, we functionalize
individual molecules, which are then intrinsically sensitive to
specific agents. These molecules are used as building blocks for
controlled growth of larger nanoscaled aggregates. The aggregates in
turn can be used as sensing elements on the meso-scale in the size
range from hundred nanometers to a few hundred microns. The organic
nanofibers thereby might become a versatile tool within nanosensor
technology, allowing sensing on the basis of individual molecules
over small aggregates to large assemblies. First experiments of
Bovine Serum Albumin (BSA) coupling to para-hexaphenyl (p-6P)
nanofibers are presented, which could lead towards a new type of protein
sensors. Besides large versatility and sensitivity, the nanofibers
benefit from the fact that they can be integrated in devices,
either in liquids by the use of microfluidic cavities or all in
parallel.
