Measuring transducers for optical diagnostic system with multifunctional unitary photovoltaic converters

(SPION-PLGA) ±PEG nanoparticles loaded with Gemcitabine as a multifunctional nanoparticle for therapeutic and diagnostic applications

Abstract The aim of this study was to develop a novel multifunctional nanoparticle, which encapsulates SPION and Gemcitabine in PLGA±PEG to form multifunctional drug delivery system. For this aim, super paramagnetic iron oxide nanoparticles (SPIONs) were synthesized and encapsulated simultaneously with Gemcitabine (Gem) in PLGA±PEG copolymers via W/O/W double emulsification me...

New Strategy of Grid Connected Photovoltaic System Using Module Integrated Converters with B4 Inverter to Overcome Partial Shading Effect

This paper proposes a new configuration for solar energy conversion systems. One challenging issue of the photovoltaic (PV) systems is partial shading, and in this paper Module Integrated Converters (MIC) are used to overcome this problem in PV arrays. A few boost converters are employed as MICs to mitigate the shading effect. Furthermore, to reduce the cost and to increase the system performan...

Integrating data converters for picoampere currents from electrochemical transducers

This paper describes a current mode A D converter designed for a maximum input current range of 5nA and a resolution of the order of IPA. The converter is designed for a potentiostat for amperometric chemical sensors and provides a constant polarization voltage for the measuring electrode. A prototype chip using the dual slope conversion method has been fabricated in a 0.7pm CMOS process. Exper...
