Abstract: A general method for producing EMS positive samples or samples containing nanostructures characteristic of self-replicating molecules like DNA by dilution and agitation. Methods of transduction into DNA information or for inducing EMS in an originating sample and transducing the EMS signal once induced into a naïve receiving sample. Diagnostic methods using this technology.

Abstract: This invention concerns a process for preparing reagents intended for a microorganism detection test and notably an infection in humans or animals, wherein the following steps are included: a) Centrifuging a biological or artificial liquid medium containing a selected specific microorganism; b) Filtrating the supernatant obtained in step (a); c) Preparing a series of diluted samples corresponding to increasing dilutions of the filtrate obtained in step (b), down to a filtrate dilution of at least a factor of 10?15; d) Submitting said diluted samples obtained in step (c) to an electrical, magnetic, and/or electromagnetic exciting field; e) Analyzing the electrical signals detected using a solenoid, as well as digitally recording said electrical signal after analog/digital conversion of said signal; f) Selecting diluted samples with which the characteristic electrical signals were obtained in (e), i.e. signals whose amplitude is at least 1.
