A dehydrated composition is provided that includes freeze-dried erythrocytic cells. In this way, the quality of the weld at the initial weld point is improved, and where intermediate wire electrodes are used, wire breaks are reliably prevented. When the signal quality assessment determines that an improved signal is available on an alternative antenna, an antenna change is performed to switch to the alternative antenna, also during a GI, again minimizing disruption in information transmission. A detectable change is brought about as a result of the hybridization of the oligonucleotides on the nanoparticles to the nucleic acid.
