Reactive oxygen species (ROS)-responsive nanomedicine for RNAi-based cancer therapy

Li, Yang; Bai, Hongzhen; Wang, Hebin; Shen, Youqing; Tang, Guping; Ping, Yuan

Although much effort has been dedicated to the development of efficient siRNA delivery for cancer therapy, delivery nanomaterials that can particularly respond to reactive oxygen species (ROS), which are overproduced in the tissue and mitochondria of cancer cells, are still rare for the clinical translation of RNA interference (RNAi)-based therapy.…

High-Efficiency Construction of CO2-Based Healable Thermoplastic Elastomers via a Tandem Synthetic Strategy

Yang, Guan-Wen; Wu, Guang-Peng

The alternating copolymerization of CO2/epoxides to polycarbonates (CO2–PCs) has been an area of research focus because of the growing concern about energy and the environment. Regardless of the enormous progress that has been made, the lack of functionalities and inert chemical structure of CO2-based polycarbonates greatly limit the scope of…

Epsilon-Fe2O3 Nanocrystals inside Mesoporous Silicas with Tailored Morphologies of Rod, Platelet and Donut

Li, Jheng-Guang; Fornasieri, Giulia; Bleuzen, Anne; Gich, Martí; Impéror‐Clerc, Marianne

The ϵ-Fe2O3 polymorph of iron oxide, which has outstanding physical properties, is successfully stabilized inside mesoporous silica particles with tailored shapes. Using mesoporous silica particles with three different morphologies of rod, platelet and donut, we obtain ϵ-Fe2O3/mesoporous silica nanocomposites. Iron oxide is loaded inside the porosity using a two steps…

Redox-Activatable ATP-Depleting Micelles with Dual Modulation Characteristics for Multidrug-Resistant Cancer Therapy

Wang, Hebin; Li, Yang; Zhang, Miaozun; Wu, Di; Shen, Youqing; Tang, Guping; Ping, Yuan

A fast adenosine triphosphate (ATP)-depleting micellar system that is activated by intracellular redox for the codelivery of anticancer drug paclitaxel (PTX) and small interference RNA (siRNA) targeting polo-like kinase1 (PLK1) is developed to address the key challenges of multidrug-resistant (MDR) cancer therapy. The ATP-depleting micelle is self-assembled from a redox-responsive…

Bioinspired Polylactide Based on the Multilayer Assembly of Shish-Kebab Structure: A Strategy for Achieving Balanced Performances

Yi, Longfei; Luo, Shanshan; Shen, Jiabin; Guo, Shaoyun; Sue, Hung-Jue

Achieving balanced mechanical performances in a polymer material has long been attractive, but it is still a significant challenge. Herein, a nonadditive strategy was proposed by tailoring the crystalline structure of neat polylactide (PLA) through a layer-multiplying extrusion. Compared with normal PLA, the layer-multiplied material exhibited a 50% increase in…

Smart release of antimicrobial ZnO nanoplates from a pH-responsive keratin hydrogel

Villanueva, María E.; Cuestas, María L.; Pérez, Claudio J.; Campo Dall′ Orto, Viviana; Copello, Guillermo J.

A smart antibacterial biomaterial based on a keratin hydrogel with pH-dependent behavior and Zinc Oxide nanoplates as biocide agent has been developed. The pH of a chronic wound is basic due to bacterial metabolism. Originally shrank at acid pH, keratin hydrogels swell upon contact with a bacterial contaminated media leading…

Determination of the packing model of a supramolecular nanofiber via mass-per-length measurement and de novo simulation

Yao, Qingxin; Bao, Qiang; Li, Xinming; Wang, Hui; Yang, Zhenyu; Shi, Xinghua; Gao, Yuan; Xu, Bing

Herein, we report an example of using scanning transmission electron microscopy to determine the mass-per-length of supramolecular nanofibers. Together with the measurement of the diameter of nanofibers via transmission electron microscopy, we could estimate the packing density of assembling molecules along the nanofibers. A parallel unbiased de novo simulation screens…

Neunert, Grażyna; Tomaszewska-Gras, Jolanta; Siejak, Przemyslaw; Pietralik, Zuzanna; Kozak, Maciej; Polewski, Krzysztof

α-Tocopherol oxalate (TO), a tocopherol ester derivative, was investigated for its effect on the structural changes of fully hydrated 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) liposomes, as a function of concentration and temperature, by applying differential scanning calorimetry (DSC), small angle X-ray scattering (SAXS), and DPH fluorescence anisotropy methods. The DSC and DPH…
