Claim 14:
15. A colorimetric sensor for detecting bacteria and/or viruses comprising:
a functional layer comprising a nanomaterial capable of generating a surface plasmon, bacteria- and/or viruses-bioresponsive;
wherein the bacteria- and/or viruses-bioresponsive nanomaterial of the functional layer comprises at least one of proteinic substances and antibodies, the functional layer being configured to act as a virus receptor, or the colorimetric sensor comprises a receptor layer comprising at least one of proteinic substances and antibodies, the receptor layer being configured to act as a virus receptor;
wherein the functional layer and the receptor layer are overlapped and in direct contact with each other; and
wherein the colorimetric sensor further comprises a plasmonic nanostructured grating comprising etched nanostructures such to generate plasmonic colors.
