The objective of this work is the synthesis of a hydrogel with Ag nanoparticles,
like a biopolymer (hydrogel/Ag), as well as its characterization, to be used in
prosthesis in 3D printing.
Hydrogels are of great interest due to its unique properties such as the high
content of water, softness, flexibility and biocompatibility. Some of the
applications of these materials it is tissue engineering. Silver nanoparticles are
used in biomedical applications by its antibacterial characteristic property. The
purpose of an anti-bacterial hydrogel is that addition to be biocompatible avoid
prosthetic
infection.
To get Hydrogel, Laponite was dispersed in water in a proportion of 3% by mass.
MBBA (cross-linker), I2959 (initiator), was later added and the monomer AMPS,
under rigorous agitation. Ag nanoparticles, previously synthesized by the
method of Turkevich, were added to the solution obtained. The obtained
Hydrogel/Ag was used to build a model with 3D printer piece, finally held a
curing through UV radiation to provide it rigidity.
We proposed to characterize the mechanical properties of tension,
compression, and rigidity. As well as the viscosity to hold in a range of 14.48-
37.22 kPa, to ensure the viability in 3D printing. The morphology was
characterized by scanning electron microscopy (SEM). The composition and
antibacterial activity were characterized by Raman Spectroscopy and Gram test,
respectively.
