Nucleic Acid Aptamers: An Emerging Tool for Biotechnology and Biomedical Sensing

Abstract: Detection of small molecules or proteins of living cells provides an exceptional opportunity to study genetic variations and functions, cellular behaviors, and various diseases including cancer and microbial infections. Our aim in this review is to give an overview of selected research activities related to nucleic acid-based aptamer techniques that have been reported in the past two decades. Limitations of aptamers and possible approaches to overcome these limitations are also discussed.

“…Since the time of its development, the aptamer technology has been used as a high‐throughput screening tool in many areas such as immunology, cell biology, molecular imaging, and pharmacology . In recent years, this technique has been applied to uncover protein receptors that are specific to markers over‐expressed in different cancers . We feel that this technique has the potential to be employed to analyze exosomes derived from different cancers.…”

“…Aptamers are a group of single stranded DNA or RNA oligonucleotides which have a wide range of research and medical application such as biosensors, bioimaging probes, therpeautic molecules and so on . Some of them, specially DNA aptamers, have the G‐rich sequences conferring them the special tertiary structure, called G‐quadruplex …”

“…Gracias a todo ello, desde hace dos décadas los aptámeros son cada vez más utilizados en investigación básica y aplicada. En concreto, se han mostrado muy útiles como sondas de bio-reconocimiento en biosensores (conocidos genéricamente como "aptasensores") y nanobiosensores de distintos tipos (Ku et al, 2015). El salto de los aptámeros desde la ciencia básica a las aplicaciones biotecnológicas se produjo en 2004, cuando la FDA aprobó el pegaptanib como el primer aptámero de uso en terapia humana (comercializado con el nombre de "Macugen"), para el tratamiento de la degeneración macular asociada a la edad (Gragoudas et al, 2004).…”
