scaffolds designed for the seeding and attaching of cells that<br />
form an implantable tissue. The composites are directly obtained<br />
through electrospinning performed on a collector that supports a<br />
unidirectional / bidirectional array of bioresorbable suture wires.<br />
A porous matrix containing micro / nanofibres is deposited<br />
through electrospinning on both sides of the as obtained<br />
composite sheet. The matrix and wires are made of different<br />
bioresorbable polymers, assuring optimal bioerosion duration,<br />
while maintaining the desired strength according to the<br />
application.<br />

Patent no. MD4106 (B1) ― 2011-04-30<br />
The invention relates to medicine, namely to a process for the<br />
obtaining of an injection oil silver nanodispersion.The process<br />
provides for the mixing in a volume ratio of 5:1 of sunflower oil<br />
for injection with an aqueous colloidal silver nanodispersion with<br />
the size of particles of 5...10 nm, obtained from silver nitrate by<br />
precipitation with sodium citrate and stabilized with<br />
Description polyvinylpyrrolidone, at the same time the mixing is carried out<br />
under stirring at a speed of 300 vol./min within 15...20 min, then<br />
it is separated the aqueous fraction, and the oil nanodispersion<br />
with the concentration of colloidal silver of 2.5...5.0 ppm is<br />
vacuum-treated at a pressure of 0.085 atm, a temperature of<br />
75...80 DEG C, during 20...30 min and packed in glass vials.The<br />
result consists in the possibility of administration of the oil silver<br />
nanodispersion by injection.<br />
