Ultrasound technologies make visible what remains hidden from our naked eyes: Physicians study tissue changes in our
bodies with the aid of sonography; submarines equipped use sonar systems to get their bearings in the darkness of the deep sea; and for
materials and components testing, ultrasound provides a non-destructive alternative to
costly technologies that are not real - time capable.
The newly developed porous films do not require an addition of
costly growth factors, and they are capable of adsorbing vascular endothelial growth factors (VEGFs) that occur naturally in the
body and taking them into the film
materials.
