The objective of the study is the development of a new technique based on supercritical technology for the production of bioabsorbable polymeric microparticles containing pharmaceutical principles, for their use in the controlled release of medicines. For this purpose, the ring-opening copolymerization of D,L-lactide and glycolide in supercritical carbon dioxide, using zinc(II) 2-ethylhexanoate...
We introduce an innovative method for patterning one or multiple types of polymeric microparticles by electrospraying them towards a collecting surface patterned with an array of microelectrodes. By independently programming the electric state of each microelectrode, microparticles can be confined within desired regions with a high patterning contrast. The patterning principle and the role of t...
With controlled nanometre-sized pores and surface areas of thousands of square metres per gram, metal-organic frameworks (MOFs) may have an integral role in future catalysis, filtration and sensing applications. In general, for MOF-based device fabrication, well-organized or patterned MOF growth is required, and thus conventional synthetic routes are not suitable. Moreover, to expand their appl...
Polymeric microparticles with hexagonal surface patterns comprising of colloids or dimples were fabricated using photocurable emulsion droplets. Colloidal silica particles within the interior of the photocurable emulsion droplets formed two-dimensional (2D) crystals at the droplet surface by anchoring on the emulsion interface, and the resulting composite structures were captured by rapid photo...
Droplet microfluidics is one of the most promising approaches that allows preparation microparticles with tailored structure and composition. Various functional have been developed using microfluidics, where their controlled shows high potential for a wide range applications. Among these, soft polymeric which exhibit low elastic modulus compared to ceramics metals are extensively investigated i...
Drug delivery has become increasingly important mainly due to the awareness of the difficulties associated with a variety of old and new drugs. Of the many polymeric drug delivery systems, biodegradable polymers have been used widely as drug delivery systems because of their biocompatibility and biodegradability. The majority of biodegradable polymers have been used in the form of microparticle...
The route for single step synthesis and encapsulation of a model hydrophilic drug onto homogeneous microparticles for controlled release applications is described. The microfluidic spray drying technique, able to handle complex fluids, was used to produce uniform particles with adjustable functionality. Here, an aqueous polymeric dispersion of Eudragit NE was used as the controlled release matr...
Objective(s) Theophylline, a xanthenes derivative, is still widely used as an effective bronchodilator in the management of asthmatic patients. It is used both as a prophylactic drug and to prevent acute exacerbations of asthma. The aim of study was to formulate and evaluate effect of the microencapsulation of theophylline loaded nanoparticles on the reduction of burst release. Materials and Me...
