Many of our applications rely on detailed control over the size and surface functionality of nanoparticles. To this end, we have recently developed an approach that allows us to synthesise gold nanoparticles in a modular fashion with detailed and independent control over both the core diameter and the ligand architecture. Our research is informed by the routine implementation of statistical tools, including Design of Experiment and our recently developed Nanoparticle Entropy method. Furthermore, we have established a novel method for the quantitative study of nanoparticle-stimuli interaction via immobilisation of NPs on a quartz crystal microbalance and use this technique for the rapid screening and validation of molecular recognition.
