Colloidal metal oxide nanocrystals offer a unique combination of excellent low-temperature solution processability, rich and tuneable optoelectronic properties and intrinsic stability, which makes them an ideal class of materials as charge transporting layers in solution-processed light-emitting diodes and solar cells. Developing new material chemistry and custom-tailoring processing and proper...

silver nanoparticles (agnps) are known to have bactericidal and fungicidal effects. since, there is few information available on the interaction of colloidal nanosilver with fish pathogens. hence, the current study investigated the effects of colloidal agnps on the in vitro growth of the fish pathogen saprolegnia sp.. before the experiments, various important properties of agnps were well-chara...

Colloidal microand nanospheres have been of continuous research interest, since their intrinsic properties can be finely tuned by changing parameters such as diameter, chemical composition, bulk structure, and crystallinity. Up to now, they have found a broad range of applications in fields such as drug delivery, biodiagnostics, combinatorial synthesis, and photonic band-gap crystals (PBG). The...

Zeta potential can help you understand and control colloidal suspensions. Examples include complex biological systems such as blood and functional ones like paint. Colloidal suspensions can be as thick as paste (like cement) or as dilute as the turbidity particles in a lake. Water, milk, wine, clay, dyes, inks, paper and pharmaceuticals are good examples of useful colloidal systems. Water is a ...

Green synthesis of nanoparticles, as fundamental building blocks of nanotechnology, has recently attracted considerable attention. Silver nanoparticles have unique physiochemical, biological and environmental properties which make them useful in a wide range of applications. In the present paper we report our research results on biosynthesis of silver nanoparticles from silver precursor usin...

Malleable biomaterials such as Herschel-Bulkley (H-B) fluids possess shear responsive rheological properties and are capable of self-assembly and viscoelastic recovery following mechanical disruption (e.g., surgical placement via injection or spreading). This study demonstrated that the addition of moderate molecular weight glycosaminoglycans (GAGs) such as chondroitin sulfate (CS) (Mw = 15-30 ...

Charged colloidal dispersions and complex plasmas share the classical many-body character of strongly coupled systems but differ in their dynamics, which is overdamped in the colloidal and almost ballistic in the complex plasma case. In this paper, we shall discuss basic properties of charged colloids and emphasize in particular their link to complex plasmas. Similarities and differences betwee...

Colloidal crystals are promising structures for photonic applications requiring dynamic control over optical properties. However, for ease of processing and reconfigurability, the crystals should be encapsulated to form 'ink' capsules rather than confined in a thin film. Here we demonstrate a class of encapsulated colloidal photonic structures whose optical properties can be controlled through ...

Hyaluronic acid (HA) is a naturally occurring biodegradable polymer with a variety of applications in medicine including tissue engineering, dermatological fillers, and viscosupplementation for osteoarthritis treatment. The cytotoxicity of crosslinking techniques for scaffold fabrication and the high viscosity of viscosupplements have been issues impeding the development of products from HA. Th...
