In the past decade, there has been an increasing interest in supramolecular systems that can undergo physical or chemical transformations upon encountering a specific stimulus. Micelle-forming amphiphilic systems based on polymers and dendrimers are particularly preferred over small molecule amphiphiles, due to their ability to sequester and release a vast library of hydrophobic guest molecules at micromolar polymer or dendrimer concentrations. Here we review a relatively underexplored, yet rapidly advancing, field of amphiphilic systems based on a dendritic architecture that exhibit stimuli sensitive behaviour. In particular, we will be focusing on stimuli such as temperature, pH, enzymatic and non-enzymatic proteins. These stimuli-responsive systems offer a unique opportunity in the field of drug delivery and sensing.
