Layered double hydroxides (LDHs) have been widely investigated due to
their several applications in the material and biotechnology industries.
The combination of silver nanoparticles with biocompatible LDH material
can create a new hybrid material with new properties. In this work,
biogenic silver nanoparticles (AgNPbio) were associated with Mg-Al LDH
to obtain the hybrid material LDH-AgNPbio. The new hybrid material
obtained was characterized by X-ray diffractometry (XRD), scanning
electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS),
transmission electron microscopy (TEM), inductively coupled plasma
optical emission spectrometry (ICP-OES) and Fourier transform infrared
spectroscopy (FTIR). LDH was efficient to absorb silver nanoparticles due to an opposite surface charge between AgNPbio (zeta = -13.2 mV) and LDH (zeta = +3.2 mV). Furthermore, AgNPbio was not lixiviated from
LDH-AgNPbio, even after five washes, indicating a strong interaction. An
important property of this hybrid material was its antimicrobial
activity against Staphylococcus aureus and Escherichia coli and absence
of cytotoxic effect to fibroblast cell (V79). This hybrid material is an
interesting and promising nanobiocomposite for biomedical and cosmetic
applications.
