Muhammad Saqib successfully defended his PhD thesis "Synthesis Of Magnetically Anisotropic Janus Particles by Droplet-Based Microfluidics" on Jan 26, 2024

Congratulations Dr. Saqib!

Muhammad Saqib's work on Janus particle synthesis within a droplet based microfluidic reactor is recently published in Langmuir. This is a simple, one step and versatile microfluidic technique to synthesize magnetically anisotropic Janus particles with a controlled size distribution.

Ecem Yelekli, Mayssam Naji and A. Selim Çanakçı's work on surface textures for oil droplet transport is recently published in Surfaces and Interfaces. In this work surface texture ratchets are used to selectively move low surface tension droplets. Motion of hexadecane droplets at a speed of 7 mm/s was achieved. The results of this study are crucial for applications of oil droplet transport such as in biochemistry, smart surface development, wearable device design as well as microsystem packaging.

Our collaborative work with Ercan Lab from the Department of Metallurgical and Materials Engineering of METU, "Antibacterial properties and osteoblast interactions of microfluidical synthesized chitosan – SPION composite nanoparticles" is recently in J. Biomedical Materials Research. In this work a multi-step microfluidic reactor was used to fabricate chitosan – superparamagnetic iron oxide composite nanoparticles (Ch – SPIONs), where composite formation using chitosan was aimed to provide antibacterial property and nanoparticle stability for magnetic resonance imaging (MRI).

MiNI Lab's recent graduate Eliza Sopubekova's work on selective nanoparticle patterning by using electrophoretic deposition is recently published in J. Nanoparticle Research. In this work electrostatic forces are applied to direct and position charged fluorescent latex and silica nanoparticles on desired areas of the surface.  alternating nanoparticle patterns and particle deposition on the same designated areas for forming composite areas are obtained.

Our collaborative work with Dr. Ali Javili of Bilkent UNiversity is selected as a supplementary cover of the April 14, 2021 issue of Langmuir. In this work, we describe a very droplet motion on local surface gradients by using a double pendulum model. This is a novel approach to predict droplet behavior.

Our collaborative work with Prof. Hilmi Volkan Demir's research group of Bilkent University and UNAM is selected as an inside cover article of the March 11, 2021 issue of the weekly journal Advanced Materials. In this work, the first microfluidic single-mode laser having CQW solution as the gain medium with a record low lasing threshold among all the other solution-based lasing methods were demonstrated.
