    Abstract: This disclosure describes a multiplexing, wireless, batteiyless multiplexing paper sensor. The sensor includes a polymeric, non-cellulosic substrate that includes a radio frequency (RF) wireless communication ultra-wide band (UWB) antenna and a sensing element disposed on the polymeric, non-cellulosic substrate with and without molecular imprinted structures to immobilize specific target chemical or biological objects. The sensor is powered when a signal is received by the RF wireless communication UWB antenna and then takes measurements of a medium being monitored by the sensor. Data corresponding to the measurements is then transmitted from the sensor via the RF wireless communication UWB antenna.

    Abstract: A system for detecting molecular structures is provided. The system includes a radio frequency (RF) wireless antenna, batteryless sensor, and a network analyzer. The sensor has an ultra-high frequency dipole antenna that transmits data to the RF wireless antenna and a sensing element. The sensing element is operatively coupled to the dipolar antenna and detects molecular structures. The network analyzer receives data from the RF wireless antenna and analyzes the data to determine a concentration of molecular structures.

    Abstract: There is a need in the point-of-care diagnostic community for an efficient and portable method for testing blood and other biological fluids that can be easily translated across multiple applications. An aspect of the invention described involves monitoring the optical properties of molecularly-mediated nanoparticle assemblies though an optically transparent and magnetically active microfluidic chip, which has recently emerged as an attractive method for biomarker detection as it is an efficient tool for monitoring the binding events that take place in a sensing assay. In one embodiment, this device is directed towards two-nanoparticle assays that rely on the assembly or disassembly of plasmonic and magnetic nanoparticles in response to a certain analyte. A further embodiment is directed to a spiral microfluidic using inertial forces to filter fluid components by size, connected to a magnetically active channel comprised of a nickel micropad array, optically transparent microchannel, and permanent magnets.

    Abstract: The present disclosure pertains to a microfluidic platform. The microfluidic platform includes a top layer having a top inlet and outlet, a center layer having a center inlet and outlet, and a bottom layer having a bottom inlet and outlet. The microfluidic platform further includes a first porous membrane between the top and center layer, a second porous membrane between the center and bottom layer, a first electrode disposed on at least one of the top and bottom layers, and a second electrode disposed on at least one of the top and bottom layers. Additionally, the present disclosure pertains to a method for selective isolation. The method includes flowing a sample through a microfluidic platform, isolating a first component from the sample in a top layer, isolating a second component from the sample in a center layer, and isolating a third component from the sample in a bottom layer.
