In this work we report how tubular lattice hollow core fibers can be successfully used as sensors for proteins such as streptavidin. After a functionalization of the silica surface, a layer of biotin was deposited on the fiber core inner surface. The fiber was than infiltrated with a solution containing streptavidin and a red shift of the fiber transmission spectrum was experimentally observed.
