Growth mechanism and electrochemical properties of hierarchical hollow SnO2 microspheres with “chest-nut” morphology

13-Sep-2017 | Huating Hu; Liming Wu; Paul Gebhardt; Xiaofei Zhang; Alexey S Cherevan; Birgit Gerke; Rainer Poettgen; Andrea Balduc ..., CrystEngComm, 2017

Hollow micropheres (HHMSs) constitute a very popular class of materials for use as drug-delivery carriers, photocatalysts and electrode materials in batteries, owing to their large, porous surface area and mechanical integrity during intercalation reactions. Here, we used a template- and ...

Coarse-grained molecular dynamics studies of the structure and stability of peptide-based drug amphiphile filaments

13-Sep-2017 | Myungshim Kang; Honggang Cui; Sharon Loverde, Soft Matter, 2017

Peptide-based supramolecular filaments, in particular filaments self-assembled by drug amphiphiles (DAs), possess great potential in the field of drug delivery. These filaments possess one hundred percent drug loading, with a release mechanism that can be tuned based on the dissociation of the ...

Magnetic nanoscale metal-organic frameworks for magnetically aided drug delivery and photodynamic therapy

13-Sep-2017 | Shalini Sharma; Komal Sethi; Indrajit Roy, New Journal of Chemistry, 2017

Magnetic nanoscale metal organic frameworks (M-NMOFs) were employed for the magnetically-aided co-delivery of chemotherapy and photosensitizer drugs to cancer cells. Chemotherapy drug doxorubicin and photosensitizer drug methylene blue were co-encapsulated within iron carboxylate M-NMOFs, from ...

Bis‐Acetyl Carbazole: Photoremovable Protecting Group for Sequential Release of Two Different Functional Groups and its Application for Therapeutic Release

09-Sep-2017 | Pradeep Singh, VENKATESH YARRA, Surajit Nandi, Maniklal Shee, Biswajit Saha, Anakuthil Anoop, European Journal of Organic Chemistry, 2017

In this paper, we present fluorescent photoremovable protecting group (FPRPG) based on bis‐acetyl carbazole for the release of two different functional groups like carboxylic acids, alcohols, thiols and amines in a sequential fashion. Dual arm caged bis‐acetyl carbazoles with different ...

Redox-Responsive Disulfide Cross-Linked PLA–PEG Nanoparticles

07-Sep-2017 | Tiziana Fuoco; Daniela Pappalardo; Anna Finne-Wistrand, Macromolecules, 2017

We have developed a strategy for the preparation of redox-responsive PEG–PLA-based nanoparticles containing disulfide bonds that can be disassembled in the presence of cellular concentrations of glutathione. Functionalized poly(lactide)s were prepared by ring-opening copolymerization of l-lactide ...

How functional groups to influence ROS generation and cytotoxicity of graphene quantum dots

06-Sep-2017 | Ya Zhou; Hanjun Sun; Faming Wang; Jinsong Ren; Xiaogang Qu, Chemical Communication, 2017

Recent studies have demonstrated that graphene quantum dots (GQDs) can cause cytotoxicity upon irradiation although GQDs have shown great potential in bioimaging, drug delivery and therapeutics. Herein, we selectively deactivate the ketonic carbonyl, carboxylic, or hydroxyl groups on GQDs, and ...

Transformative Nanomedicine of an Amphiphilic Camptothecin Prodrug for Long Circulation and High Tumor Uptake in Cancer Therapy

06-Sep-2017 | Fuwu Zhang; Guizhi Zhu; Orit Jacobson; Yi Liu; Kai Chen; Guocan Yu; Qianqian Ni; Jing Fan; Zhen Yang; Frederick Xu; ..., ACS Nano, 2017

We report a camptothecin (CPT) prodrug that was well formulated in solution and rapidly transformed into long-circulating nanocomplexes in vivo for highly efficient drug delivery and effective cancer therapy. Specifically, using a redox-responsive disulfide linker, CPT was conjugated with an ...

Core–Shell–Corona Silica Hybrid Nanoparticles Templated by Spherical Polyelectrolyte Brushes: A Study by Small Angle X-ray Scattering

06-Sep-2017 | Haoya Han; Li Li; Weihua Wang; Yuchuan Tian; Yunwei Wang; Junyou Wang; Regine von Klitzing; Xuhong Guo, Langmuir, 2017

Core–shell–corona silica/polymer hybrid nanoparticles with narrow size distribution were prepared in the template of spherical polyelectrolyte brushes (SPB) which consist of a solid polystyrene (PS) core densely grafted with linear poly(acrylic acid) (PAA) chains. The microstructure of obtained ...
