摘要：
A material, article, system and method include a probe composition that includes a hydrophobic portion, a hydrophilic portion, an analyte-binding portion and a fluorophore portion. The analyte-binding portion is configured to bind to an analyte in an aqueous solution. The fluorophore portion is configured to change an optical property of fluorescent light emitted in response to incident excitation light when the probe composition changes between a first state in which the analyte is not bound to the analyte-binding portion and a second state in which the analyte binds to the analyte-binding portion. A material includes the probe composition and a silicone hydrogel substrate having a hydrogel network that allows flow of aqueous solution through the solution and a silicone network that occupies interstices of the hydrogel network. A contact lens having the material enables remote detection of glucose concentration in tear fluid of a subject.
