Structural and functional complexity in synthetic cells from amphiphilic DNA nanostars
… building blocks, with cholesterol-terminated DNA nanostars being one example. These amphiphilic structures, named C-stars, have been shown to self-assemble through non-specific hydrophobic interactions, forming condensates with long-range order capable of hosting various functionality. In this …

Gold nanostars: from catalytic and SERS properties to the development of smartphone-based and portable biosensing approaches for food contaminants
… in this thesis. For that purpose, gold nanostars have been synthesised following a seed-mediated bottom-up approach, which enables to control the optical and morphological properties of the resulting nanoparticles. Gold nanostars have shown potential to replace biological enzymes as …

Plasmonic Nanoplatforms and Surface-enhanced Raman Spectroscopy for in vivo Sensing: from Plants to Animals
… Plasmonic nanomaterials, such as gold nanostars (AuNS) a hallmark particle pioneered by the Vo-Dinh group, increase inherently weak Raman signals from molecules providing an intense and unique SERS spectrum allowing for targets to be sensitively detected and easily identified. For this …

Bioenabled Synthesis of Anisotropic Gold and Silver Nanoparticles
… APMNs with varied morphologies such as branched nanostars and triangular nanoprisms have been successfully prepared. We first presented the preparation of gold nanostars (Au NSTs) through a two-step approach utilizing a common Good's buffer, HEPES, as a weak reducing agent. Single crystalline Au …

Crystalline frameworks self-assembled from amphiphilic DNA nanostructures
… amphiphilic cholesterol-functionalised DNA nanostars, \emph {C-stars}. C-stars combine key advantages of all-DNA motifs and conventional amphiphilic molecules -- allowing for the preparation of expanded crystalline frameworks with tunable properties and embedded functionality.

PREPARATION OF NANO- AND MOLECULAR COMPOUNDS FOR ANTITUMORAL APPLICATIONS TRIGGERED BY LIGHT
… drug. In the first project, the surface of gold nanostars (GNS) was functionalized with a polyamidoamine-Ru(II) complex to increase the PDT efficiency of the complex, i.e. to produce ROS upon irradiation, due to the metal-enhanced 1O2 generation promoted by GNS. Another possible advantage of such …

MSC DERIVED EV IN REGENERATIVE MEDICINE
… in the joint, both were labelled with gold nanostars and Supra Magnetic Iron Oxide Nanoparticles (SPION). These labelled cells and EV were then injected into a sheep stifle 1 week post creation of an OA model (meniscal transection model). These labelled cells and EV could then be seen within …

Simulation informed design of stimuli responsive structures and higher-order assemblies in DNA nanotechnology
… flexibility dependent phase of amphiphilic DNA nanostars. Conversely, one of the goals in structural DNA nanotechnology is the manufacture of materials with unusual mechanical properties. Here, I report the formation of a DNA origami with negative Poisson's ratio: when tension is applied in one …
