High demand for pathogen detection gives boost to research trends focusing on the
development of fast, highly sensitive, label-free, miniature devices. The use of diamond in such
structures allows for taking advantage of its unprecedented set of properties as high chemical
stability, optical transparency, electronic functionality and robust biointerfaces and
biocompatibility. The idea is not only to enhance analyte diffusion and surface area, but more
importantly to explore physico-chemical phenomena that would change our view on the present
biosensing concepts. The aim of the D4CaPLa project is to take advantage of the latest
advances in diamond nanotechnology and biosensing achieved in the PL and CZ teams and
thereby design, produce, and analyse function of new heterogeneous diamond
nanoarchitectures enhanced with Au-nanoparticles and bio-functionalized with antibody
receptors. A unique approach is the characterization (and control) of combined optical and
electrochemical processes and signals, with view to improving recognition of virus antigens
