Abstract
Provided herein is a sensing apparatus comprising, at least one LSPR light source, at least one detector, and at least one sensor for LSPR detection of a target chemical. The sensor comprises a substantially transparent, porous membrane having nanoparticles immobilized on the surface of its pores, the nanoparticles being functionalized with one or more capture molecules.
Claims16
A sensing apparatus comprising:
- i. at least one LSPR light source;
- ii. at least one detector;
- and
- iii. at least one sensor for LSPR detection of a target chemical located between the detector and the light source, the sensor comprising a substantially transparent, porous membrane, the membrane comprising nanoparticles immobilized on the surface of its pores, the nanoparticles being functionalized with one or more capture molecules.
1 more element
A method of preparing a sensor comprising the steps of:
- i. forming nanoparticle binding layers on the inside of the AAO pores through physical or chemical means;
- ii. applying a surface stabilizing additive to the surface of the membrane;
- iii. applying a nanoparticle solution to the inside of the AAO pores.
