Sharp change indicators : A new class of time–temperature indicators (TTIs) based upon aqueous suspensions of triangular silver nanoplates with relatively sharp corners has been developed. Such nanoplates display localized surface plasmon resonance peaks in the visible region, the positions of which are highly sensitive to the sharpness of the corners.
