A new design of a macro-to-micro interface that can be used for simple and reliable control comprehensive microfluidic cell culture processes is introduced making procedures easily accessible to biological laboratories. The novel evaluated by adapting workflow single-cell, pair, cluster encapsulation into hydrogel beads acting as 3D microenvironment with subsequent long-term cultivation. For th...

Engineering of new heterogeneous metal-free catalysts is great importance for persulfate activation. Herein, Innovative conductive polymers Polyaniline (PANI) and Polypyrrole (PPy) were used as promising PS activation to effectively degrade organic pollutants. In fact, PANI PPy can provide the necessary electron transfer based on nitrogen atoms located in conjugated chains compared their counte...

Lemongrass (Cymbopogon citratus) is a medicinal plant with various biological activities such as antibacterial, antifungal, antiprotozoal, anti-inflammatory, and antioxidant. This study aimed to encapsulate lemongrass bioactive in alginate/chitosan complex by enhancing the properties of CaCl2 crosslinked incorporated tween 80 ionic gelation method. The hydrogel was prepared mixing alginate solu...

In this paper, we report on the effect of patterned non-adhesive hydrogel nanosurfaces on the self-assembly of highly ordered colloids. Polyethylene glycol (PEG) hydrogel is employed as the substrate material in the study, for its desired non-adhesive property, and biocompatibility as well as photopatternability. Ultrafine PEG features are photopatterned onto glass substrates with minimal featu...

Although roughly 40% of pharmaceuticals being developed are poorly water soluble, this class of drugs lacks a formulation strategy capable of producing high loads, fast dissolution kinetics, and low energy input. In this work, a novel bottom-up approach is developed for producing and formulating nanocrystals of poorly water-soluble active pharmaceutical ingredients (APIs) using core-shell compo...

The mechanical properties of microscopic particles have been a heated research object for it takes the deformation of micro-beads in the microfluidic environment into account. Sufficient knowledge on mechanical properties of micro-beads would lead to better device design and application for cell mechanics, tissue engineering, etc. The physical properties of alginate beads were examined both in ...
