Tissue engineering can be easily described as the in vitro seeding and attachment of human cells onto a scaffold in order to develop new tissue. The application of polymers as scaffolds may bring interesting properties, such as bioresorbability, biocompatibility, mechanical behavior closer to that presented by the original tissue. Poly (Lactic-coGlycolic Acid) (PLGA) and Poly(Isoprene) (PI) wer...

A new type of hybrid three-dimensional scaffolds was prepared using poly(ɛ-caprolactone) (PCL) and chitosan-modified montmorillonite by solvent casting and particulate leaching method. The scaffolds were characterized by scanning electron microscopy coupled with energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and dynamic mechanical analysis to study the structural and mechanical ...

Hydroxyapatite (HAp) nanorod embedded composite was prepared using poly (vinyl alcohol) (PVA) as a matrix with different weight percentages (wt. %) The role of PVA composition on the crystallite size, degree of crystallinity, functional groups and morphology of nanocomposites were characterised by XRD, FTIR, and TEM analysis. The results indicated that the size and crystallinity of HAp nano par...

For over 20 years, nanostructured porous silicon (nanoPS) has found a vast number of applications in the broad fields of photonics and optoelectronics, triggered by the discovery of its photoluminescent behavior in 1990. Besides, its biocompatibility, biodegradability, and bioresorbability make porous silicon (PSi) an appealing biomaterial. These properties are largely a consequence of its part...

     The bone mineral consists of tiny hydroxyapatite (HA) crystals in the nanoregime. Nanostructured HA is also expected to have better bioactivity than coarser crystals. This paper reports on the in vitro evaluation of bone like HA nanopowders. The prepared HA nanopowder was characterized for its phase purity, chemical homogeneity and bioactivity. Fourier transform infrared (FT-IR) s...

Biopolymeric patches show enormous potential for the regeneration of infarcted myocardium tissues. However, most them usually lack appropriate mechanical performance, stability in water, and important functionalities; instance, antioxidant activity. Protein nanofibrils, such as lysozyme nanofibrils (LNFs), are biocompatible nanostructures with excellent water insolubility, activity exploited to...
