3.1.6. Alginates
It is a non-branched linear poly-
saccharide. Used in wound dressings and burns based on 
genes[6]. Obtained from treated algae such as calcium, 
sodium and collagen genes are absorbent bandages of 
natural fibers. Among its properties, it can absorb large 
quantities of body fluids 20 times the size. Other mate-
rials such as zinc genes and silver genes have been ob-
tained that have antimicrobial, wound and burn proper-
ties[4] [8]. 
3.1.7. Agar:
It is a natural biological material obtained 
from continuous fibers in the ethanol coagulation bath 
using a mixture of dimethyl sulfoxide as a suitable sol-
vent. Among its properties is that it is swollen by 400 - 
50% and a tensile strength of 30 - 50 MPa [8]. 
3.1.8.Glycosaminoglycan
Hyaluronic acid from 
ECM is known to be a non-immunomodulatory linear 
glycemic, obtained from N-acetyl-d-glucosamine and 
glucuronic acid and has an effect on wound healing [4].
3.2. Synthetic polymers
Synthetic polymers are complex nanomaterials with 
small pores and very high surface area, manufactured 
with different technologies. Used to heal wounds and 
burns, most of them by electrical fixation, in order to 
produce nanofibers. Its characteristics: it has excellent 
mechanical properties, suitable hydrolysis also, thermal 
stability. 
3.2.1. Polyurethane
Polyurethane was first used to 
produce fibrous nanoparticles as an alternative to the 
skin in 2003. It found excellent properties such as good 
oxygen permeability, fluid discharge capacity, and the 
ability to classify water vapor transmission, as an anti-
microbial. The obligation is to reduce the polyurethane pol-
ymer and it can be overcome by coating it with collagen or 
collagen-based peptides, which greatly increases the ad-
hesion and biocompatibility properties [2, 6].
