Particulate matter (PM) has been of great concern in China due to the increasing haze pollution in recent years. In 2012, the Chinese national ambient air quality standard (NAAQS) was amended with a "more strict" regulation on the PM concentrations, i.e., 35 and 70 µg/m(3) for annual PM2.5 and PM10 averages, respectively (Grade-Ⅱ, GB3095-2012). To evaluate… (More)
Cell culturing, whether for tissue engineering or cell biology studies, always involves placing cells in a non-natural environment and no material currently exist that can mimic the entire complexity of natural tissues and variety of cell-matrix interactions that is found in vivo. Here, we review the vast range of hydrogels, composed of natural or synthetic… (More)
New nanocarrier platforms based on natural biological building blocks offer great promises in revolutionalizing medicine. The usage of specific protein cage structures: virus-like particles (VLPs) for drug packaging and targetted delivery is summarized here. Versatile chemical and genetic modifications on the outer surfaces and inner cavities of VLPs… (More)
Many smart materials in bioengineering, nanotechnology and medicine allow the storage and release of encapsulated drugs on demand at a specific location by an external stimulus. Owing to their versatility in material selection, polyelectrolyte multilayers are very promising systems in the development of microencapsulation technologies with permeation… (More)
We report herein the encapsulation of a water-soluble phthalocyanine (Pc) into virus-like particles (VLPs) of two different sizes, depending on the conditions. At neutral pH, the cooperative encapsulation/templated assembly of the particles induces the formation of Pc stacks instead of Pc dimers, due to an increased confinement concentration. The… (More)
Carbonaceous aerosols have been attracting attention due to the influence on visibility, air quality, and regional climate. Statistical analyses based on concentration levels, spatial-temporal variations, correlations, and organic carbon (OC) to element carbon (EC) ratios from published data of OC and EC in particulate matter (PM2.5 and PM10) were carried… (More)
A functional negatively charged polyelectrolyte, polyferrocenylsilane (PFS) was encapsulated in cowpea chlorotic mottle virus (CCMV) capsid proteins, yielding monodisperse particles of 18 nm in size with altered redox properties compared to the parent materials.
A series of water-soluble macro-initiators is synthesized to avoid radical loss in microfluidic on-chip photo cross-linking of hyaluronic acid methacrylate-containing water-in-oil emulsions. Their superior performance over known photo-initiators through the generation of water-soluble radicals and excellent biocompatibility are demonstrated.
Layer by layer (LbL) organometallic multilayers, composed of poly(ferrocenylsilane) (PFS) polycations and polyanions, were fabricated and characterized. Disassembly of redox responsive PFS(-)/PFS(+) films as well as multilayers consisting of PFS(-)/PFS(+) combined with redox inert bilayers was studied. The influence of parameters on disassembly kinetics and… (More)
Redox-responsive poly(ferrocenylsilane) (PFS) polymer molecules were attached individually to gold surfaces for force spectroscopy experiments on the single molecule level. By grafting ethylenesulfide-functionalized PFS into the defects of preformed self-assembled monolayers (SAMs) of different omega-mercaptoalkanols on Au(111), the surface coverage of PFS… (More)
