“…The proposed approach offers new opportunities for the quantification of miRNAs for concomitant diagnoses and treatments of early-stage cancers [46,47]. Ma et al [48] have recently reported a new nucleic acid multicolor fluorescent probe using silica-coated symmetric gold nanostars (S-AuNSs@SiO 2 ) for highly sensitive, in situ real-time imaging of P53 mRNA, Bax mRNA, and cytochrome c (Cyt c) during T-2 toxin-induced apoptosis. The probe design included first the attachment of carboxyl group-modified nucleic acid chains to the surface of S-AuNSs@SiO 2 using an amide-forming reaction.…”

Raman nanoparticle probes are a potent class of optical labels for the interrogation of pathological and physiological processes in cells, bioassays, and tissues. Herein, we review the recent advancements in fluorescent and Raman imaging using oligodeoxyribonucleotide (ODN)-based nanoparticles and nanostructures, which show promise as effective tools for live-cell analysis. These nanodevices can be used to investigate a vast number of biological processes occurring at various levels, starting from those involving organelles, cells, tissues, and whole living organisms. ODN-based fluorescent and Raman probes have contributed to the achievement of significant advancements in the comprehension of the role played by specific analytes in pathological processes and have inaugurated new possibilities for diagnosing health conditions. The technological implications that have emerged from the studies herein described could open new avenues for innovative diagnostics aimed at identifying socially relevant diseases like cancer through the utilization of intracellular markers and/or guide surgical procedures based on fluorescent or Raman imaging. Particularly complex probe structures have been developed within the past five years, creating a versatile toolbox for live-cell analysis, with each tool possessing its own strengths and limitations for specific studies. Analyzing the literature reports in the field, we predict that the development of ODN-based fluorescent and Raman probes will continue in the near future, disclosing novel ideas on their application in therapeutic and diagnostic strategies.
