Abstract: Some embodiments described herein relate to a method that includes receiving an optical emission signal from a sensor disposed in a vessel. The vessel can be configured for an in vitro biological process (e.g., a bioreactor), and the emission signal can be received while the sensor is in contact with a biological matrix. The emission signal can be received by a reader that is disposed outside the vessel. At least one of a presence, quantity, or concentration of an analyte can be determined based on the emission signal. Similarly stated, the emission signal emitted by the sensor can be dependent on at least one of a presence, quantity, or concentration of the analyte. In some embodiments, the emission signal can be an optical signal emitted by a sensor in response to the sensor being excited by an excitation optical signal emitted by, for example, the reader.

Abstract: A system includes implantable sensors and monitors and are operable to provide health-related feedback to users based on data received from the implantable sensors and monitors.

Abstract: Some embodiments described herein relate to an apparatus, such as an inserter, having a housing and a needle at least partially disposed within the housing. An actuator can be coupled to the needle and configured to move the needle between an actuated configuration and a retracted configuration. A wire can be at least partially disposed within the needle. The wire can be fixedly and immovably coupled to the housing. In some embodiments a biosensor can be disposed within the needle and the apparatus can be configured to deliver or implant the biosensor to a patient, for example, under the patient's skin. The biosensor can constructed of a non-rigid material, such as hydrogel. In some embodiments, the apparatus can be configured to deliver or implant the biosensor without applying a force to the biosensor.
