Advancements in branched bottlebrush polymers for responsive, targeted imaging
Multi-modality and stimuli responsive nanoparticles are promising platform materials for medical imaging and diagnostics. Specifically magnetic resonance imaging (MRI) and nearinfrared (NIR) fluorescent probes can be used in combination to visualize biodistribution and in vivo clearance rates. We …

Studio di formulazione e caratterizzazione di nanoparticelle a base di trimetil chitosano e sodio alginato per il rilascio mirato di farmaci
The purpose of this study was to develop positively charged nanoparticles (NPs) based on trimethyl chitosan (TMC) and sodium alginate (SA) as drug delivery systems able to interact with the sialic residues of the mucous membranes. The TMC has been synthesised in our laboratory slightly modifying …

Degradable polymeric nano-films and particles as delivery platforms for vaccines and immunotherapeutics
… we also developed biodegradable core-shell nanoparticles with a PBAE core enveloped by a phospholipid bilayer shell for cytosolic delivery, with a view towards delivery of messenger RNA (mRNA)-based vaccines. The pH-responsive PBAE component was chosen to promote endosome disruption, while …
