Any substance(as an aggregate of atoms or molecules), whether a gas, liquid, or solid, in a fine state of subdivision with particles too small to be visible in an ordinary optical microscope that is dispersed in a continuous gaseous, liquid, or solid medium and does not settle or settles very slowly(as the liquid droplets in fog, solid particles in smoke, bubbles in foam, or gold particles in ruby glass).  2, fiche 1, Anglais, - colloid

Many colloids occur naturally. Others can be prepared by breaking large pieces of material into smaller pieces, as with a colloid mill ... Some colloids can be prepared by condensation methods, in which atoms or molecules are induced to aggregate from solution, or in which atoms or molecules are condensed from the vapor state. There are three important types of colloids: small solid particles having the same internal structure as the bulk solid phase (sulfur suspensions in water), aggregates formed from smaller molecules (soaps in water, and large molecules of colloidal size (proteins and high polymers).  3, fiche 1, Anglais, - colloid

Bio-therapy is based on the treatment using living organisms and has an obvious growth potential... Today, maggots from the gold fly are sent in special textile bags, consisting of a fine-pored PVA [polyvinyl alcohol] external layers and an internal, closed nylon net with spacers. This facilitates the use of maggots to combat wound infection, although they are not visible. The latest research at the IHB [Institute for Hygiene and Bio-technology] has the aim of isolating which substances in the maggots are chemically significant and coupling them to a textile carrier. The idea is that this slowly dissolves in stages over time in the wound, releasing the active agents in a controlled manner.  2, fiche 3, Anglais, - biotherapeutic%20textile

La biothérapie grâce à des organismes vivants, par exemple les vers de la mouche verte de la viande, Lucilia sericata, est [...] une piste à suivre. Ceux-ci empêche la nécrose de la plaie, régulent l'infection et permettent la régénération des tissus. Des textiles spécifiques, munis d'une poche poreuse et d'un filet de nylon contenant ces vers stériles sont développés pour panser les plaies. Le but est de bénéficier des capacités soignantes des vers sans les exposer à la vue du patient. Dans le même ordre d'idées, l'institut Hohensteiner cherche également à isoler les molécules soignantes de ces vers afin d'en imprégner un pansement.  1, fiche 3, Français, - textile%20bioth%C3%A9rapeutique
