Multivalent aptamer–RNA based fluorescent probes for carrier-free detection of cellular microRNA-34a in mucin1-expressing cancer cells†
Abstract
In this study, multivalent carrier-free aptamer–RNA based fluorescent probes (CF-probes) were designed as a simpler, more reliable, timesaving strategy for cellular miRNA detection. CF-probes spontaneously delivered into cells without the need for additional carriers and visualized target microRNA-34a specifically.
