When are trillions of options insufficient? Evidently when creating aptamers.
Short strands of DNA or RNA called aptamers, which can bind to particular target receptors, can be very helpful for determining disease markers, treating disease, and measuring metabolites and proteins in biological research. They act similarly to antibodies, but they are simpler to create and incorporate into biosensors, more stable at room temperature, have a longer shelf life, and are much less likely to cause unwelcome immune reactions.
Finding the ideal aptamer for a particular task can be challenging, even though there are countless configurations available. Aptamers are typically
