The exit of nanoparticles from solid tumours
Nanoparticle retention inside tumours has been associated with lymphatic vessel collapse. It is now shown that nanoparticles exit from solid tumours through lymphatic vessels in or surrounding the tumour by a nanoparticle-size-dependent mechanism.

A nanoparticle-based strategy for the imaging of a broad range of tumours by nonlinear amplification of microenvironment signals
The imaging of tumours is challenging because of the wide range of different cancers. Now, the rapid detection of tumours, independent of type, is achieved using a nonlinear amplification strategy that employs ultrasensitive pH-responsive fluorescent nanoparticles that illuminate within tumour neovasculature or in response to the tumour’s acidic extracellular environment.

Strategies for advancing cancer nanomedicine
Cancer nanomedicines approved so far minimize toxicity, but their efficacy is often limited by physiological barriers posed by the tumour microenvironment. Here, we discuss how these barriers can be overcome through innovative nanomedicine design and through creative manipulation of the tumour microenvironment.

Nanoparticles that communicate in vivo to amplify tumour targeting
A two-component nanoparticle system that communicates and enhances in vivo drug delivery and diagnostics has been devised. The system comprises ‘signalling’ nanoparticles that target tumours and then broadcast the tumour’s location to ’receiving’ nanoparticles in circulation, which carry therapeutic or diagnostic cargos, hence amplifying tumour targeting.
