Microfluidic diatomaceous earth analytical devices (μDADs) comprising highly porous photonic crystal biosilica channels are disclosed. The μDADs can simultaneously perform on-chip chromatography to separate small molecules from complex samples and acquire the surface-enhanced Raman scattering spectra of the target chemicals with high specificity. The ultra-small dimensions of the diatomaceous earth microfluidic channels and the photonic crystal effect from the fossilized diatom frustules allow unprecedented sensitivity down to ppb-level.
