A detection system for determining lysyl oxidase-like 2 protein levels in a bodily sample, includes at least one reaction solution for generating H2O2 upon combination with LOXL2 in the bodily sample, the reaction solution including lysine that can be oxidatively deaminated by LOXL2 to generate \u03b1-aminoadipic-\u03b4-semialdehyde and hydrogen peroxide. Its extensible framework is designed for quick attachment to a plethora of different carts and to remain in place despite the twisting of the golf cart frame and any jostling of the golf cart as it traverses about the course. Servo data is read in a time window following a transition from write mode to read mode, with a frequency passband that has a first low frequency corner. Supersonic vibration can be efficiently provided to the substrate by irradiating with a laser beam with ultrasonic vibration while keeping the end portion of the substrate.
