Process for realising a device for collecting and transferring samples for molecular biology

A sampling swab (1) for collecting and transferring samples for molecular biology comprising:

• a support body (2), having at least a first portion (2a), and a plurality of fibres (6) attached and arranged on the first portion (2a) of the support body (2) by flocking, such as to define a flocked collecting portion (3) destined to collect, on the collecting portion (3), a quantity of sample for molecular biology, and
• a surfactant, wherein the plurality of fibres (6) are pre-treated with the surfactant, such as to increase a quantity of DNA or RNA releasable by the collecting device and usable for molecular biology operations;
• wherein the plurality of fibres (6) pre-treated with the surfactant are configured to conserve and preserve the sample on the flocked collecting portion (3) for a predetermined period of time of at least twenty-four hours;
• and
• wherein the surfactant is a mixture of chlorides of alkyl-benzyl-dimethyl ammonium, in which the alkyl group varies from octile (C8H17—) to octadecyl (C18H37—).
