Distinguishing Between Monomeric scFv and Diabody in Solution Using Light and Small Angle X-ray Scattering

Lüdel, Frank; Bufe, Sandra; Bleymüller, Willem M.; de Jonge, Hugo; Iamele, Luisa; Niemann, Hartmut H.; Hellweg, Thomas

Depending on the linker length between the V H and the V L domain, single-chain Fv (scFv) antibody fragments form monomers, dimers (diabodies) or higher oligomers. We aimed at generating a diabody of the anti-MET antibody 3H3 to use it as crystallization chaperone to promote crystallization of the MET ectodomain…

Chirality Transfer in Coassembled Organogels Enabling Wide-Range Naked-Eye Enantiodifferentiation

Yue, Bingbing; Yin, Liyuan; Zhao, Wandong; Jia, Xiaoyong; Zhu, Mingjie; Wu, Bin; Wu, Si; Zhu, Liangliang

Enantiodifferentiation is crucial in organic chemistry, pharmacochemistry, material chemistry, and life science. However, it remains tremendously challenging to achieve a broad enantioselectivity to different types of chiral substrates via a single-material design. Here, we report a coassembled organogel strategy with chirality transfer to make an enantioselective generality possible. This…

Preparation and liquid crystal phase properties of discotic cellulose nanoparticles

Li, Chenxi; Evans, Julian; Wang, Nan; Guo, Tingbiao; He, Sailing

Understanding the behavior of fluids with inhomogeneous structural properties is critical for many industrial and biological materials. Sulfuric acid hydrolysis of cotton with ultrasonic treatment and low-speed centrifugation during purification yields “spiky” discotic cellulose particles. Amorphous cellulose remained in solution and forms discotic units which may be nucleated by crystalline…

Improvement of Antialveolar Echinococcosis Efficacy of Albendazole by a Novel Nanocrystalline Formulation with Enhanced Oral Bioavailability

Hu, Chunhui; Liu, Zhengsheng; Liu, Chengyu; Zhang, Yaogang; Fan, Haining; Qian, Feng

Alveolar echinococcosis (AE) is a chronic infectious parasitic disease that is fatal and still being neglected. Currently, the AE treatment recommended by the WHO is complete excision of the lesions, followed by the oral administration of albendazole (ABZ), the only effective first-line anti-AE drug, for two years. Unfortunately, complete excision…

Differential Polymorphic Transformation Behavior of Polybutene-1 with Multiple Isotactic Sequences

Ma, Ya-Ping; Zheng, Wei-Ping; Liu, Chen-Guang; Shao, Hua-Feng; Nie, Hua-Rong; He, Ai-Hua

For the solid-solid transformation from form II to form I of isotactic polybutene-1 (iPB), the temperature dependence of form I nucleation and growth was deemed to control the transformation process. However, the relationship between form I formation and form II disappearance in the transformation process is not clear. In this…

Elaboration of microporous CeO2 thin layers having nanocrystallites network controlled by Pluronic P123: Impact of key experimental parameters

Lu, Zijie; Rébiscoul, Diane; Causse, Jeremy; le Goff, Xavier; Mollard, Nicolas; Deschanels, Xavier

Microporous ceria thin films having nanocrystallites network were synthesized by evaporation-induced self-assembly process, using P123 amphiphilic copolymer as structure-directing agent. The impact of key experimental parameters, i.e., the sol ageing, the relative humidity (RH), the thermal treatment, on the thin layer elaboration were investigated. The results show that the organization…

Influence of hydrogen bonding on the crystallization behavior of poly(ethylene oxide)/ionic liquids mixtures

Li, Wenze; Gong, Pengjian; Huang, Yajiang; Niu, Yanhua; Li, Guangxian

Two types of imidazolium-based ionic liquids (ILs) and and their mixtures were blended with poly(ethylene oxide) (PEO) matrix to tune the strength of intermolecular hydrogen bonding in the system. With the addition of ILs, particularly increasing ratio, significantly reduced overall crystallization kinetics in the order of pure…

How Confinement Affects the Nucleation, Crystallization, and Dielectric Relaxation of Poly(butylene succinate) and Poly(butylene adipate) Infiltrated within Nanoporous Alumina Templates

Safari, Maryam; Maiz, Jon; Shi, Guangyu; Juanes, Diana; Liu, Guoming; Wang, Dujin; Mijangos, Carmen; Alegría, Ángel; Müller, Alejandro J.

This work describes the successful melt infiltration of poly(butylene succinate) (PBS) and poly(butylene adipate) (PBA) within 70 nm diameter anodic aluminum oxide (AAO) templates. The infiltrated samples were characterized by SEM, Raman, and FTIR spectroscopy. The crystallization behaviors and crystalline structures of both polymers, bulk and confined, were analyzed by…

Towards mechanical robust yet self-healing polyurethane elastomers via combination of dynamic main chain and dangling quadruple hydrogen bonds

Hu, Jin; Mo, Ruibin; Jiang, Xiang; Sheng, Xinxin; Zhang, Xinya

One of the greatest challenges of robust self-healing materials is the confliction between high chain mobility for self-healing and a stable structure for mechanical strength. Herein, dangling 2-ureido-4-pyrimidione (UPy)-functionalized side groups were introduced into the hard segments of thermoplastic polyurethane (TPU) elastomers, where embedded the dynamic disulfide bonds in the…

Aescin-Induced Conversion of Gel-Phase Lipid Membranes into Bicelle-like Lipid Nanoparticles

Geisler, Ramsia; Pedersen, Martin Cramer; Hannappel, Yvonne; Schweins, Ralf; Prévost, Sylvain; Dattani, Rajeev; Arleth, Lise; Hellweg, Thomas

Mixtures of the phospholipid 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) and the saponin ?-aescin spontaneously form monodisperse, bilayered discoidal micelles (also known as “bicelles” or “nanodisks”) in aqueous solution. Such bicelles form below the melting temperature of DMPC when the phospholipids are in the rigid L?? state and are precursors of spontaneously formed vesicles.…
