One-dimensional single crystal incorporating functional nanoparticles of other materials could be an interesting platform for various applications. We studied the encapsulation of nanoparticles into single-crystal ZnO nanorods by exploiting the crystal growth of ZnO in aqueous solution. Two types of nanodiamonds with mean diameters of 10 nm and 40 nm, respectively, and polymer nanobeads with si...

Efavirenz is a drug with an absorption window. Its oral bioavailability is 40-50%. The aim of this work was to formulate solid self-emulsifying drug delivery system to improve the solubility and bioavailability of efavirenz. Solubility of Efavirenz was determined in various vehicles like oils, surfactants and co surfactants. Which, upon dilution with aqueous media, spontaneously form fine oil i...

One approach to solve the problem of hypogonadism is to restore the steriodogenic function of Leydig cells through cell transplantation. In order to dodge the immune response, the implanted cells need to be micro-encapsulated in PEGdA hydrogel. The size of the microcapsules affects the diffusion of oxygen and nutrients, which in turn have an impact on cell viability. We determined the three-dim...

Microfluidic technologies have recently been shown to hold significant potential as novel tools for producing micro- and nano-scale structures for a variety of applications in tissue engineering and cell biology. Over the last decade, microfluidic spinning has emerged as an advanced method for fabricating fibers with diverse shapes and sizes without the use of complicated devices or facilities....

A wafer-level functionality testing and characterisation system for ISFETs (ionsensitive field-effect transistor) is realised by means of integration of a specifically designed capillary electrochemical micro-droplet cell into a commercial wafer prober-station. The developed system allows the identification and selection of “good” ISFETs at the earliest stage and to avoid expensive bonding, enc...

Even after a century, heparin is still the most effective anticoagulant available with few side effects. The poor oral absorption of heparins triggered the search for strategies to achieve oral bioavailability since this route has evident advantages over parenteral administration. Several approaches emerged, such as conjugation of heparins with bile acids and lipids, formulation with penetratio...
