Aspects of the present disclosure provide an improved out-of-service scan method that can increase the speed of acquiring service while avoiding unnecessary full scan, thus reducing scan time andor power consumption of a user equipment. A portion of the container is provided with a sensate substance which is released into the chamber to impart an organoleptic characteristic to a recipient product within said chamber. Thereafter, the center-cut holes are loaded with delay detonators and explosives and the center-cut holes are stemmed with stemming material at their entrances. In the memory modules, parallel access for the number of bits corresponding to the width of the memory access data bus is assured. The method includes illuminating the food sample solution or the body fluid on the nano-scale surface structure on the sensor by a laser beam; obtaining a Raman spectrum from the scattered light using a spectral analyzer; and identifying the spectral signature in the Raman spectrum to determine the existence of the chemical substance in the food product or identifying a disease in the individual.
