Abstract A new delivery microdevice, based on hydrophobic oleic acid‐capped mesoporous silica particles and able to payload release in the presence of surfactants, has been developed. The oleic acid functionalization confers to the system a high hydrophobic character, which avoids cargo release unless surfactant molecules are present. The performance of this oleic‐acid capped microdevice in the presence of different surfactants is presented and its zero‐release operation in the absence of surfactants is demonstrated.
