TiO2 semiconducting nanoparticles are known to be photocatalysts of moderate activity due to their high band-gap and high rate of electron-hole recombination. The formation of a shell of carbon around the core of TiO2, i.e., the formation of TiO2@C nanoparticles, is believed to partly alleviate these problems. It is usually achieved by a hydrothermal treatment in a presence of a sugar derivativ...

In nature, cells perform a variety of complex functions such as sensing, catalysis, and energy conversion which hold great potential for biotechnological device construction. However, cellular sensitivity to ex-vivo environments necessitates development of bio-nano interfaces which allow integration of cells into devices and maintain their desired functionality. In order to develop such an inte...

Encapsulation of compounds into nano- or microsized organic particles of narrow size distribution is of increasing importance in fields of advanced imaging and diagnostic techniques and drug delivery systems. The main technology currently used for encapsulation of molecules within uniform template particles while retaining their size distribution is based on particle swelling methodology, invol...

Starch nanoparticles resist digestion in the upper intestine but not colon. They are proven to exert prebiotic effects on human body. Starch-based have generated a great interest food and agriculture sector due their biocompatibility, wide array of natural sources ease modification. In current study, two starch (rice water chestnut) were used synthesize for encapsulation probiotic bacteria. Obt...

The purpose of this study was to optimize the formulation of lactoferrin nano-liposomes using response surface methodology. Response surface methodology based on central composite rotatable design has been successfully used to model and optimize biochemical and biotechnological processes. The mass ratio of phosphatidylcholine and cholesterol (1-8), lactoferrin concentration (2-15 mg/mL), tween8...

A significant amount of academic and industrial research efforts are devoted to the encapsulation of active substances within microor nanocarriers. The ultimate goal of core–shell systems is the protection of the encapsulated substance from the environment, and its controlled and targeted release. This can be accomplished by employing “stimuli-responsive” materials as constituents of the capsul...

The aim of this study was to enhance the transdermal delivery of Sildenafil Citrate by encapsulation in nano sized ultra deformable vesicles, transfersomes. The thin film hydration and sonication technique was utilized in the preparation of Sildenafil Citrate loaded Transfersomes and both non ionic and ionic edge activators (anionic and cationic) were used in varying ratios to study their effec...

Persistent pain remains a major health issue: common treatments relying on either repeated local injections or systemic drug administration are prone to concomitant side-effects. It is thought that an alternative could be a multifunctional cargo system to deliver medicine to the target site and release it over a prolonged time window. We nano-engineered microcapsules equipped with adjustable ca...
