Described herein are interferometric sensors that can be used for biochemical testing. Each interferometric sensor includes an interference layer immobilized along a surface of a monolithic substrate. Analyte binding molecules can be coated along a surface of the interference layer. During biochemical testing, when analyte molecules in a sample bind to the analyte binding molecules, a biological layer will form. The monolithic substrate has a higher refractive index than the interference layer. Furthermore, the interference layer can be designed to have a refractive index that is substantially similar to a refractive index of the biological layer.

This utility model discloses a motion module for a biochemical testing instrument, comprising: a mounting base, a mounting side plate fixedly mounted on one end of the mounting base, a lifting slide arm slidably mounted on one end of the inner side of the mounting side plate, and a telescopic slide block slidably mounted on one end of the inner side of the lifting slide arm; in this utility model, a stepper motor controls the rotation of a rotating lead screw, which drives the fixed lead screw sleeve screwed to it to slide up and down, thereby driving the lifting slide arm and the telescopic slide block to rise and fall. Simultaneously, during the upward and downward sliding of the fixed lead screw sleeve, the telescopic adjustment gear is connected to the fixed lead screw sleeve via a transition ring, thus controlling the rotation of the lead screw through the lead screw hole connected to the rotating lead screw while it is rising and falling. At this time, the internal rack meshing with the telescopic adjustment gear drives the telescopic slide block to synchronously slide horizontally within the lifting slide arm, thereby achieving more efficient synchronous lifting and telescopic positioning of the sample tube.

Introduced here is an approach to programmatically addressing the absorbance of light by analyte molecules whose binding, for example, to an interferometric sensor, is being monitored by an interferometric sensing system. A first light signal may be shone upon a biolayer over the course of a biochemical test, and the light reflected by the biolayer may form a second light signal that is detectable by a detector of an interferometric sensing system. Through analysis of the second light signal, the second light signal can be deconvolved into a reflection component and an absorbance component. If the principal component of the second light signal is the reflection component, then one algorithm may be employed to establish the binding magnitude. If the principal component of the second light signal is the absorbance component, then another algorithm may be employed to establish the binding magnitude.
