چکیده

This paper reports a microfluidic synthesis method for manufacturing magnetochromatic microspheres. The magnetochromatic microspheres are magneto-responsive color-changing microparticles in which embedded magnetic nanoparticles diffract different colors of light depending on their nanoscale interparticle spacing within their one-dimensional (1D) arrangements [1]. Our microfluidic approach in combination with magnetic self-assembly and photopolymerization process allows us to synthesize the magnetochromatic microspheres with desired size and color. By virtue of dynamic color-tuning capability during the synthesis, microspheres with heterogeneous color distribution can also be obtained. After synthesis color modulation of the microspheres is also possible through rotation of the microspheres.

Integration of polymer and metal microstructures using liquid-phase photopolymerization

In this paper we demonstrate, using a fabrication technique, liquid-phase photopolymerization (LP3) for the relatively fast and low-cost integration of thick polymers and electroformed metal microstructures to develop a range of microfluidic components and systems. Liquid-phase UV-photosensitive polymers, similar to negative-tone photoresists, are used to create both polymer microstructures and...

Formulation and Evaluation of Magnetic Microspheres Of Cytarabine

Cytarabine is the drug of choice for treatment of leukemia. However, many formulations have been prepared, due to certain limitations they could not prove to be effective ones, therefore magnetic microspheres are formulated as they minimize the Reticuloendothelial clearance and target site specificity can be increased. The current study aimed to utilize nanotechnology to develop magnetic micros...
