| description | Molecular gates: A new approach in developing controlled drug‐delivery systems using aptamers as nanovalves is presented. For the proof of principle, mesoporous silica nanoparticles were modified with a hairpin form of ATP‐binding DNA, which allows encapsulation and release of guest molecules controlled by ATP. This reversible aptamer‐based nanogate function could provide novel trigger systems for any desired biological stimulus in drug‐delivery applications. |
