Benefiting from extreme phase singularities of reflected light induced by strong plasmon-mediated energy confinements, the metasurface demonstrates a much-improved sensitivity to molecular bindings nearby and achieves an ultralow detection limit of 1 × 10−18 M for 7.3 kDa 24-mer single-stranded DNA.||URI:||https://hdl.handle.net/10356/100121
