Here, we show that a Tamm plasmon (TP) device, consisting of a SiO\n                    <jats:sup>2<\/jats:sup>\n                    \/TiO\n                    <jats:sup>2<\/jats:sup>\n                    distributed Bragg reflector capped with nanostructured silver, responds to SARS\u2010CoV\u20102 virus\u2010like particles (VLPs) in a concentration\u2010dependent manner without selective functionalization. Upon VLP exposure, the conventional wavelength shift (\n                    <jats:italic>\u0394\u03bb<\/jats:italic>\n                    ) of the TP resonance is small (\u223c4\u00a0nm), whereas the resonance depth decreases systematically, by about 60% at 10\u00a0ng\/mL VLP. To capture both spectral and amplitude changes, we define a displacement angle, \u03b1, from the translation vector of the Tamm dip before and after exposure.\n                    <jats:italic>\u03b1<\/jats:italic>\n                    increases monotonically with VLP concentration, from 1.3\u00b0\u00a0\u00b1\u00a02\u00b0 at 0\u00a0ng\/mL to 9.7\u00b0\u00a0\u00b1\u00a00.5\u00b0 at 10\u00a0ng\/mL. Control experiments with similarly sized polystyrene nanoparticles and heat\u2010denatured VLPs yield negligible changes (0.7\u00b0\u00a0\u00b1\u00a01.9\u00b0 and \u22120.7\u00b0\u00a0\u00b1\u00a04\u00b0, respectively), indicating sensitivity to the native conformational state of viral surface proteins rather than generic nanoparticle morphology or bulk refractive\u2010index effects.
