Title: System with buffer for lateral flow on a porous membrane

Abstract

Systems are described, based on a primary binding compound and a secondary binding compound used in combination with a support to detect a target in a sample. The systems includes at least one support structure, at least one small primary support portion containing at least one molecule covalently bound to a visual colloidal marker, a plurality of secondary support portions comprising secondary binding compounds that are covalently bound to the support portions and chemically active, at least one pH litmus indicator, at least one pH strip, a buffer for lateral flow on the porous membrane support that allows preservation and activity of binding compounds.

Methods and systems for Raman and optical cross-interrogation in flow-through silicon membranes

Patent Bond, Tiziana C.; Letant, Sonia E.

Cross-interrogating photonic detection systems and methods are shown. A flow through photonic crystal membrane with a surface enhanced Raman scattering (SERS) substrate is provided with pores which are distributed along multiple regions. The pores of one region have walls to which a first type of target specific anchor can be attached, while pores of another region have walls to which a second type of target specific anchor can be attached. An optical arrangement out-of-plane to the SERS substrate is also provided for enhanced sensitivity and identification of target organisms.

Lateral acoustic wave resonator comprising a suspended membrane of low damping resonator material

Patent Olsson, Roy H.; El-Kady, Ihab F.; Ziaei-Moayyed, Maryam; ...

A very high-Q, low insertion loss resonator can be achieved by storing many overtone cycles of a lateral acoustic wave (i.e., Lamb wave) in a lithographically defined suspended membrane comprising a low damping resonator material, such as silicon carbide. The high-Q resonator can sets up a Fabry-Perot cavity in a low-damping resonator material using high-reflectivity acoustic end mirrors, which can comprise phononic crystals. The lateral overtone acoustic wave resonator can be electrically transduced by piezoelectric couplers. The resonator Q can be increased without increasing the impedance or insertion loss by storing many cycles or wavelengths in the high-Q resonator material,more » « less
