Publication date: Available online 20 February 2020Source: Chinese Chemical LettersAuthor(s): Wenqi Yu, Maxim Shevtsov, Xianchun Chen, Huile GaoAbstractRecent days, aggregatable nanoparticles, which can specifically respond to certain stimulus, have shown great potential in tumor-targeted drug delivery with prolonged retention and deeper penetration. In this review, we summarize recent advances in design of aggregatable nanoparticles by different stimuli. Internal (pH and enzyme) and external (light, temperature and ROS) stimuli are introduced for a comprehensive description. Moreover, the aggregated nanoparticles usually exhibit photothermal, photoacoustic, PET and enhanced MRI contrast, which is also described. In the end, we discuss about the potential applications and challenges for the future clinical translation.Graphical abstractWe summarize different stimuli-responsive nano-aggregations, internal and external stimuli are introduced and the nanoaggregates extraordinary enhanced nanoparticles’ accumulation and penetration in tumor site.
