Fig. 3. Upon mixing MOR-1 with water a fine suspension is immediately formed (left vial), whereas MOR-1–HA is clearly separated from water (right vial). This is confirmed by the illumination of the mixtures with a laser pointer. Thus, the laser beam can be easily observed as it travels through the liquid in the left vial (Tyndall effect), whereas it is invisible when it travels through the clear solution in the right vial.
