The main advantage of optoacoustic imaging (OAI) is the capability to detect diseases at their early stages of growth. The efficiency of this technique has been demonstrated by preliminary studies with real biological tissues and small animals. The definitive goal of in-vivo OAI is to provide maps of the absolute concentration of chromophores with the […]

A customized optical system composed of collimating and focusing lenses is proposed to achieve the beam focusing of high-brightness diode laser bars with high fill factor for optoacoustic applications. Through an optimized design, the beam of a 940-nm diode laser bar is first collimated and symmetrized between the fast and slow axes, and then is […]

The purpose of this study was to prepare and to characterize a new formulation of injectable capsaicin loaded poly (D,L-lactic-co-glycolic acid) (PLGA) microspheres (CAP-MS). The emulsion solvent evaporation process based on O/W emulsion was applied to prepared the CAP-MS with optimization of formulation using uniform design with three factors and six levels. The optimized formulation […]

Hydroxyapatite (HAp) – polycaprolactone (PCL) composite has found enhanced interest as scaffold material for bone tissue engineering application. The HAp phase is bioactive and provide the favorable environment for cell adhesion, proliferation, differentiation and cell conduction whereas the biodegradable PCL provide the required flexibility, mouldability and resorbability. Nanoparticles of HAp has been synthesized by precipitation […]

In this study one of classical antibiotic compound nitrofurantoin was studied as micro and nano particles in electrochemical analysis by cyclic voltammetric technique using glassy carbon electrode in blood medium to observe the oxidative effect on the blood components. It was found oxidation – reduction current peaks of nitrofurantoin in blood medium at +1 and […]
