摘要： A sensor comprises a plurality of colloidal particles assembled into an array. Each particle has a specific chemical receptor bound to a surface of each of the particles and functionalised to respond to a target stimulus. A lattice constant of the array changes in response to the target stimulus or the particles are embedded in a gel which deforms in response to an action of the target stimulus.

摘要： The present invention relates to a sensor for detecting chemical, biological, biochemical or other environmental stimuli, and includes a plurality of colloidal particles having chemical receptors bound to each particle's surface, wherein when a target stimulus is directed to the bound chemical receptor, the gelled matrix contracts or expands, which changes the lattice constant, thereby changing the pattern of diffracted light in a measurable manner so that the target stimulus' presence can be detected by a spectrometer. The plurality of colloidal particles are composed of a material having a first dielectric constant, and the gel and surrounding medium have a second dielectric constant. The colloidal particles can be assembled using holographic optical tweezers and polymerized to create an integrated sensor array, which diffracts light in a detectable characteristic manner.
