What is Stimulus-Responsive Oligonucleotide Conjugation?

Stimulus-responsive oligonucleotide conjugations are oligonucleotide-based conjugates that are capable of responding to specific external stimuli by undergoing structural or functional changes in response to the stimulus, thereby allowing for controlled release, activation, or modulation of their properties.

• Classification of Stimulus-Responsive Oligonucleotide Conjugation

Various types of stimulus-responsive oligonucleotide conjugates are designed using a variety of stimuli, including changes in pH, temperature, light, enzyme activity, or the presence of specific molecules.

• pH-Responsive Oligonucleotide Conjugation:

  Oligonucleotides can be coupled to pH-responsive switches, such as acid-unstable junctions or pH-sensitive polymers, which are couples that remain stable at normal physiological pH but rapidly degrade or release payload in an acidic environment (e.g., the nucleosome or lysosome of a cell). pH-responsive oligonucleotide conjugations are valuable for targeted drug delivery or intracellular release of therapeutics.

• Temperature-Responsive Oligonucleotide Conjugation:

  Oligonucleotides can be coupled to temperature-responsive molecules, which can undergo reversible changes in conformation or solubility in response to temperature changes. Temperature-responsive oligonucleotide conjugations can be used for temperature-triggered drug release, tissue engineering, or bioseparation applications.

• Light-Responsive Oligonucleotide Conjugation:

  Oligonucleotides can be conjugated with photosensitizers that undergo structural changes or release of oligonucleotide payloads upon exposure to specific wavelengths of light. Photoresponsive conjugates provide spatial and temporal control of oligonucleotide release or activation, allowing for precise manipulation in biological systems at a distance.

• Enzyme-Responsive Oligonucleotide Conjugation:

  Oligonucleotides can be coupled to enzyme substrates designed to undergo enzymatic cleavage or conformational changes in the presence of specific enzymes. Enzyme-responsive conjugates enable targeted delivery, signal amplification and controlled release in the presence of specific enzymes, and therefore have a wide range of applications in drug delivery and biosensing.
