Conventional methods of manipulating particles with light, such as optical tweezers and optical tractor beams, rely on beam-shaping to realize complex electromagnetic field profiles and are thus sensitive to scattering. Here, we show that by introducing tailored optical asymmetry in the particle, we can realize a novel guiding method that is controllable by the frequency of light, without regar...

Human PNAS-4 (hPNAS-4), as a pro-apoptotic gene, can inhibit tumor growth when overexpressed in some malignant cells. Poly (lactic-co-glycolic acid) (PLGA) was used as a gene transfer vector due to the advantage of sustained release, nontoxicity and biodegradability. In this study, we aimed to investigate the effect of PLGA nanoparticles encapsulating hPNAS-4 combined with cisplatin (DDP) on ov...

Crystalline porous materials (CPMs) have attracted considerable research attention in recent years for their wide applications many fields, such as the energy storage and conversion, gas separation storage, water purification, catalysis, optoelectronics, sensors, drug delivery, etc. The of CPMs derive from superiorities tunable structures, abundant functionalities, excellent chemical stability,...

Chemoprevention is a practical approach to control colorectal cancer, which is one of the major causes of cancer mortality in the United States. Based on our recent silibinin efficacy studies in human colorectal cancer cells, we investigated the effects of its dietary feeding on azoxymethane (AOM)-induced aberrant crypt foci (ACF) formation and associated biomarkers in male Fisher 344 rats. Fiv...

•m-SiO2-PEG shows less destruction to the vascular system than f-SiO2•m-SiO2-PEG intravasation and extravasation prevents cancer cells from migrating upon intracellular endocytosis The fast-growing investigations of mesoporous silica (m-SiO2) have been offering great opportunities for nanomedicine. Recently, highly agglomerated fumed (f-SiO2) sintered by elevated temperatures without any surfac...
