1. An isolated protector polynucleotide for reversible binding to an sgRNA, consisting of or comprising the structure of Formula (I),
T-S-L  (I)
wherein,
T comprises a targeting sequencing domain polynucleotide that reversibly hybridizes to a target binding domain of an sgRNA;
S comprises a stem domain polynucleotide sequence that forms a hairpin structure when said protector polynucleotide is not bound to said sgRNA; and
L comprises a linker polynucleotide sequence having a first end attached to said S, and a second end for attachment to a nanostructure,
wherein the protector polynucleotide and the sgRNA are separate nucleic acid molecules and wherein said T is displaceable from said sgRNA upon exposure of the isolated protector polynucleotide to a low-power NIR laser.
