Influence of Inclined Chip Angles on Dynamic Contact Angle Variations in Digital Microfluidics [PDF]

MATEC Web of Conferences
The impact of tilted angles on contact angles of water droplets in digital microfluidics was investigated. Experiments were conducted tilting the chip from 0 to 10 degrees at voltage increments of 50V from 250V to 400V DC.

A 3D Human Neuron‐on‐Chip Platform to Monitor Neuronal Injury Responses

Advanced Healthcare Materials, EarlyView.
This study presents a novel 3D Neuron‐on‐Chip model that can maintain human PSC‐derived excitatory prefrontal cortex neurons in 3D hydrogels and can be used to monitor neuronal injury responses over time. Results show injury‐induced acute neuronal excitotoxicity, declining neuronal connectivity, and the activation of a neurodegenerative, SASP‐like ...

Digital microfluidic biosensors

, 2023
In recent years, digital microfluidics (DMF) has emerged as a powerful tool for the manipulation over individual droplets in integrated microfluidic devices. In DMF, discrete droplets at low volume can be individually controlled to merge, mix, split, and dispense from reservoirs through an array of electrodes.

Digital Microfluidic System with Vertical Functionality [PDF]

Micromachines, 2015
Digital (droplet) microfluidics (DµF) is a powerful platform for automated lab-on-a-chip procedures, ranging from quantitative bioassays such as RT-qPCR to complete mammalian cell culturing. The simple MEMS processing protocols typically employed to fabricate DµF devices limit their functionality to two dimensions, and hence constrain the applications ...
