RESUMEN
DNA is a biological polymer that encodes and stores genetic information in all living organism. Particularly, the precise nucleobase pairing inside DNA is exploited for the self-assembling of nanostructures with defined size, shape and functionality. These DNA nanostructures are known as framework nucleic acids (FNAs) for their skeleton-like features. Recently, FNAs have been explored in various fields ranging from physics, chemistry to biology. In this review, we mainly focus on the recent progress of FNAs in a pharmaceutical perspective. We summarize the advantages and applications of FNAs for drug discovery, drug delivery and drug analysis. We further discuss the drawbacks of FNAs and provide an outlook on the pharmaceutical research direction of FNAs in the future.
RESUMEN
Nano-biosensors have elicited considerable scientific interest in various research areas, including nanotechnology, bio-technology, microelectronics, and analytical techniques. The development of nanomaterials and nanotechnology has produced nano-bio-sensors with increasing potential applications in disease diagnosis. Prostate cancer is a malignant tumor that seriously threatens the health human males worldwide. Detecting the low-abundance biomarkers of prostate cancer is critical for its early diagnosis, treatment monitoring, and evaluation of its postsurgical recurrence. This review focuses on the research progress in nano-biosensing technology and its application in the detection of prostate cancer biomarkers.
