The present invention relates to an apparatus and method for grasping, retaining, inverting, coating and transporting a plurality of frangible conical confection shells. Using the particular sulfur-containing amino acid derivative, a method of measuring an endogenous low-molecular-weight compound specifically and conveniently with high sensitivity can be provided. A scanning station is adapted to scan the pages of a document. The metallic nanoparticles cover the bottom surface andor the side surface. The change in the first tuning voltage causes a change in source-to-body capacitance of the PFET.
