two plates. The purpose of this method is to transfer the droplet from a lower planar surface to an upper parallel planar surface and back down via electrostatic forces. The physics behind such particle actuation and perpendicular movement can be understood from early works of N. N. Lebedev and I. P. Skal’skaya. In their research, they attempted to model the Maxwell electrical charge acquired by a perfectly round conducting particle in the presence of a uniform magnetic field caused by a perfectly-conducting and infinitely-stretching surface. Their model helps to predict the Z-direction motion of the microdroplets within the device as it points to the magnitude and direction of forces acting upon a micro droplet. This can be used to help accurately predict and correct for unwanted and uncontrollable particle movement. The model explains why failing to employ dielectric coating on one of the two surfaces causes reversal of charge within the droplet upon contact with each electrode and in turn causes the droplets to uncontrollably bounce of between electrodes. Digital microfluidics (DMF), has already been readily adapted in many biological fields. By enabling three-dimensional movement within DMF, the technology can be used even more extensively in biological applications, as it could more accurately mimic 3-D microenvironments. A large benefit of employing this type of method is that it allows for two different environments to be accessible by the droplet, which can be taken advantage of by splitting the microfluidic tasks among the two surfaces. For example, while the lower plane can be used to move droplets, the upper plate can carry out the necessary chemical and/or biological processes. This advantage can be translated into practical experiment protocols in the biological community, such as coupling with DNA amplification.This also allows for the chip to be smaller, and to give researchers more freedom in designing platforms for microdroplet analysis. All-terrain droplet actuation (ATDA) All-terrain microfluidics is a method used to transport liquid droplets over non-traditional surface types. Unlike traditional microfluidics platform, which are generally restricted to planar and horizontal surfaces, ATDA enables droplet manipulation over curved, non-horizontal, and inverted surfaces. This is made possible by incorporating flexible thin sheets of copper and polyimide into the surface via a rapid prototyping method. This device works very well with many liquids, including aqueous buffers, solutions of proteins and DNA, and undiluted bovine serum. ATDA is compatible with silicone oil or pluronic additives, such as
