Here, we present an electrochemical biosensor for PML/RARα fusion gene detection using carbon dots functionalized graphene oxide (CDs/GO) nanocomposites modified glassy carbon electrode (CDs/GO/GCE).Materials and Methods: In this work, the CDs/GO nanocomposites are produced through π-π stacking interaction and could be prepared in large quantities by a facile and economical way. The CDs/GO nanocomposites were decorated onto electrode surface to improve the electrochemical activity and as a bio-platform attracted the target deoxyribonucleic acid (DNA) probe simultaneously.Results: The CDs/GO/GCE was fabricated successfully and exhibits high electrochemical activity, good biocompatibility, and strong bioaffinity toward the target DNA sequences, compared with only the pristine CDs on GCE or GO on GCE. The DNA biosensor displays excellent sensing performance for detecting the relevant pathogenic DNA of APL with a detection limit of 83 pM (S/N = 3).Conclusion: According to the several experimental results, we believe that the simple and economical DNA biosensor has the potential to be an effective and powerful tool for detection of pathogenic genes in the clinical diagnosis.Keywords: acute promyelocytic leukemia, pathogenic genes, electrochemical biosensor, ex-situ method, carbon nanomaterialsZhang ZYHuang LXXu ZWWang PLei YLiu ALDove Medical Pressarticleacute promyelocytic leukemiapathogenic geneselectrochemical biosensorex-situ methodcarbon nanomaterialsMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 16, Pp 3497-3508 (2021) |
