Cancer is a complex disease associated with combination of abnormal physiological process and exhibiting dysfunctions in multiple systems. To provide effective treatment diagnosis for cancer, current strategies simultaneously focus on various tumor targets. Based the rapid development nanotechnology, nanocarriers have been shown to exhibit excellent potential cancer therapy. Compared nanoparticles single functions, multifunctional are believed be more aggressive potent context targeting. However, not simply an upgraded version original function, but involves sophisticated system proper backbone, optimized modification sites, simple preparation method, efficient function integration. Despite this, many well-designed promising therapeutic emerged recently. Here, give detailed understanding analyzation currently developed nanoparticles, their platform structures organic or inorganic backbones were systemically generalized. We emphasized functionalization strategies, which additional functions nanoparticle. also discussed application that involved nanoformulations functional crosstalk.

Abstract Sentinel lymph node imaging and biopsy is important to clinical assessment of cancer metastasis, novel non-radioactive lymphographic tracers have been actively pursued over the years. Here, we develop gold molecular clusters (Au 25 ) functionalized by phosphorylcholine (PC) ligands for NIR-II (1000–3000 nm) fluorescence draining nodes in 4T1 murine breast CT26 colon tumor mouse models. The Au-phosphorylcholine (Au-PC) probes exhibit ‘super-stealth’ behavior with little interactions serum proteins, cells tissues vivo, which differs from indocyanine green (ICG) dye. Subcutaneous injection Au-PC allows mapping at an optimal time ~ 0.5 − 1 hour postinjection followed rapid renal clearance. Preclinical LN affords high signal background ratios safety biocompatibility, promising future translation.
