An explosive detection system for detecting explosive trace in a sample includes a detection unit, and a processing unit. The detection unit that receives a desorbed sample includes a first heater, a second heater, a first resistance temperature detector (RTD), a second RTD, and an amplifier. The first heater is exp...

Various embodiments of the methods and systems disclosed herein provide a detection system that detects concentration of an analyte biomolecule (e.g., a protein, a biomarker, etc.) in a sample (e.g., a blood sample) to diagnose a disease. The detection system includes one or more micro- cantilevers that are immobili...

An asymmetric immobilization process that immobilizes a one or more receptor biomolecules on one or more solid surfaces is provided. The asymmetric immobilization process includes the following steps: (i) activating the one or more solid surfaces using an oxidizing agent; (ii) treating the one or more solid surfaces...

A method for identifying one or more gases present in an environment is disclosed. The method includes varying, by a micro-hotplate, a temperature associated with a metal-oxide gas sensor for sensing presence of the one or more gases in the environment, wherein the metal-oxide gas sensor comprises one or more semico...
