Hydroxyapatite Nanoparticles Fortified Xanthan Gum-Chitosan Based Polyelectrolyte Complex Scaffolds for Supporting the Osteo-Friendly Environment.

Nanoparticle-reinforced polymer-based scaffolding matrices as artificial bone-implant materials are potential suitors for bone regenerative medicine as they simulate the native bone. In the present work, a series of bioinspired, osteoconductive tricomposite scaffolds made up of nano-hydroxyapatite (NHA) embedded xanthan gum-chitosan (XAN-CHI) polyelectrolyte complex (PEC) are explored for their bone-regeneration potential. The Fourier transform infrared spectroscopy studies confirmed complex formation between XAN and CHI and showed strong interactions between the NHA and PEC matrix.

Bioactive Gum Arabic/κ-Carrageenan-Incorporated Nano-Hydroxyapatite Nanocomposites and Their Relative Biological Functionalities in Bone Tissue Engineering.

The present frontiers of bone tissue engineering are being pushed by novel biomaterials that exhibit phenomenal biocompatibility and adequate mechanical strength. In this work, we fabricated a ternary system incorporating nano-hydroxyapatite (n-HA)/gum arabic (GA)/κ-carrageenan (κ-CG) with varying concentrations, i.e.

In vitro anthelmintic effect of biologically synthesized silver nanoparticles on liver amphistome, Gigantocotyle explanatum.

In order to ensure global food security a rationale approach is required to control all those factors which directly or indirectly affect the food productivity. The neglected helminthic diseases alone are responsible for huge economic losses to the agrarian stakeholders. The problem is further compounded by the emerging drug resistance in flukes against the commonly used anthelmintics like triclabendazole.

Trigonella foenum graecum seed polysaccharide coupled nano hydroxyapatite-chitosan: A ternary nanocomposite for bone tissue engineering.

Biomimetic nanocomposites containing hydroxyapatite and natural polymers are promising candidates for bone grafting. In this work, a tricomponent bioactive nanocomposite (nHA-CH-TFSP) assembling nano-hydroxyapatite (nHA), Chitosan (CH) and Trigonella foenum graecum seed polysaccharide (TFSP) was developed using co-precipitation method and investigated against bicomponent nHA-CH nanocomposite for bone tissue engineering. In contrast to nHA-CH nanocomposite, nHA-CH-TFSP nanocomposite exhibited rough and interconnected porous structure as revealed by SEM with the porosity (60.

Synergistic combination of natural bioadhesive bael fruit gum and chitosan/nano-hydroxyapatite: A ternary bioactive nanohybrid for bone tissue engineering.

In this work, we have explored the polysaccharide nature of bael fruit gum (BFG) motivated from the current findings about the substantial role of the polysaccharides in bone tissue engineering. The nanocomposite scaffold (CSH-BFG) was prepared by blending BFG, nano-hydroxyapatite (n-HA) and chitosan (CS) by co-precipitation approach and compared with n-HA and CS binary system (CSH). The analysis of different properties was carried out by SEM, TEM, FTIR, XRD and mechanical testing.

Fabrication and characterization of nanoengineered biocompatible n-HA/chitosan-tamarind seed polysaccharide: Bio-inspired nanocomposites for bone tissue engineering.

In this communication we describe the fabrication of nano-hydroxyapatite/chitosan-tamarind seed polysaccharide (n-HA/CS-TSP) nanocomposite with a weight ratio of 70/20/10, 70/15/15 and 70/10/20, respectively through a co-precipitation method. A comparative assessment of the properties of n-HA/CS-TSP and n-HA/CS nanocomposites was done by FT-IR, SEM-EDX, TEM, TGA/DTA, XRD and mechanical testing. The results suggested strong chemical interactions between the three components, decreased particle size and homogeneous dispersion of n-HA particles in n-HA/CS-TSP as compared to n-HA/CS.
