Abstract:
Aptamers are a new class of oligonucleotides generated from in vitro selection with a high affinity and specificity. In this paper, a novel luminescence detection method was developed by using RNA aptamers and a DNA light switching complex, [Ru(phen)2(dppz)]2+, as a signaling aptamer for the detection of drug tobramycin. The results showed that the method was highly sensitive and selective with the detection limit down to 10 nmol/L. The method was also very simple and could realize direct detection without separation in solution, and offers a new approach for the exploitation and application of aptamers in drug analysis.
