Abstract: Provided is an analytical device including: a self-flowing microfluidic system, having a sample extraction location, at least one sample preparation location, and at least one sample analytical chamber; wherein the sample extraction location, the sample preparation location, and the at least one sample analytical chamber are interconnected by at least one microfluidic channel on a first substrate; and a signal readout system, having at least one sample analysis elements, and a data gathering and processing element.

Abstract: A spatially selective surface functionalization device configured to generate a pattern of micro plasmas and functionalize a substrate surface may include: a pattern management system, a patterning head, and a gas delivery system, wherein the gas delivery system provides a primed gas mixture for forming a plasma between the patterning head and a target substrate below the patterning head. A patterning head may generate a distribution of micro plasmas from individual directed beams of electrons with spatial separation. A pattern management system may store and manipulate information about a pattern of surface functionalization and generate instructions for regulating a distribution of micro plasmas that functionalize a substrate surface.

Abstract: A self-flowing microfluidic analytical chip may undergo spontaneous flow of a fluidic sample through microfluidic channels without an internal or external pump or corresponding pumping support hardware for fluid pumping. A self-flowing microfluidic analytical device includes sample preparation locations, sample analysis locations, and sample extraction locations connected by a network of microfluidic channels. Self-flowing characteristics of a microfluidic analytical chip result from maskless patterning of a substrate surface, where sequential passes of a patterning head preserve, rather than destroy, a pattern of surface functionalization. Self-flowing properties may be preserved by avoiding use of mask-removing solvents common to mask-removal steps in traditional microfluidic chip manufacturing processes.
