A targeted approach to cancer imaging and therapy

Imaging macrophages with nanoparticles

Nanomaterials have much to offer, not only in deciphering innate immune cell biology and tracking cells, but also in advancing personalized clinical care by providing diagnostic and prognostic information, quantifying treatment efficacy and designing better therapeutics. This Review presents different types of nanomaterial, their biological properties and their applications for imaging macrophages in human diseases, including cancer, atherosclerosis, myocardial infarction, aortic aneurysm, diabetes and other conditions. We anticipate that future needs will include the development of nanomaterials that are specific for immune cell subsets and can be used as imaging surrogates for nanotherapeutics. New in vivo imaging clinical tools for noninvasive macrophage quantification are thus ultimately expected to become relevant to predicting patients' clinical outcome, defining treatment options and monitoring responses to therapy.

Design of multifunctional FePt/GO nanocomposites for targeting, dual-modal imaging diagnostic and in situ therapeutic potential theranostic platform

In this work, highly monodispersed chemically disordered face centered cubic (fcc) FePt nanoparticles (NPs) were assembled on graphene oxide (GO) surface to form FePt/GO nanocomposites via a simple polyol protocol.

Simultaneous and multisite tumor rapid-target bioimaging through in vivo biosynthesis of fluorescent gold nanoclusters

In vivo simultaneous and multisite tumor rapid-targeting through specifically biosynthesized gold nanoclusters could be readily followed and monitored by real-time fluorescence imaging.

A facile synthesis of small-sized and monodisperse hexagonal NaYF4:Yb3+,Er3+ nanocrystals

Small-sized (∼11.86 nm) hexagonal NaYF₄:Yb³⁺,Er³⁺ nanocrystals have been synthesized by simultaneously controlling the nucleation and growth process.
