A novel approach of differentiation of adenoma and carcinoma in lung cancer based on biogenic in situ synthesis of gold nanostructures on various oligonucleotide motifs
A unique approach is introduced for constructing gold nanocrystals (AuNCs) with RNA motif–directed morphologies in a sequence-independent manner and its applications in the clinical area are described. By using this method, a label-free LSPR-based detection method for the SOX2OT transcript, long non-coding RNAs (lncRNAs), which is a prognostic indicator of poor survival in lung cancer patients is presented. For the first time, we examined how the structural changes of RNA after the heteroduplex formation with a specific DNA probe can change the morphology and LSPR band of AuNCs. Using this method, is was possible to differentiate lung squamous cell carcinoma from adenocarcinoma samples without a need for a prior amplification of the target lncRNA. The approach of using specific DNA probe enables the in situ synthesis of nanocrystals in a different way and expands this method for future translational medicine, particularly detection of specific RNA.
期刊介绍：
As a peer-reviewed journal for analytical sciences and technologies on the micro- and nanoscale, Microchimica Acta has established itself as a premier forum for truly novel approaches in chemical and biochemical analysis. Coverage includes methods and devices that provide expedient solutions to the most contemporary demands in this area. Examples are point-of-care technologies, wearable (bio)sensors, in-vivo-monitoring, micro/nanomotors and materials based on synthetic biology as well as biomedical imaging and targeting.
