“…Razek et al 2016 conducted a study about the scaffold made of kenaf fiber. Kenaf fiber was coated by hydroxyapatite (HA) by immersing it in simulated body fluid containing hydroxyapatite molecules at different day intervals [60]. The result shows an increase in HA deposit while maintaining the mechanical characteristics of the kenaf fiber.…”

Cellulose is the most common polysaccharide that can be obtained from many resources. Plant-based cellulose (PC) is preferable due to its high renewability and availability in nature. This inherent affluence naturally opens the door to new applications for this adaptable material. PC provides various potential applications such as packaging, textile, and biomedical application. Currently, PC shows progress in its feasibility in biomedical applications because it fulfills the requirement of the characteristics of biomaterials such as biocompatible, biodegradable, anti-microbial, and enhancing tissue regeneration. Different morphological forms of PC such as fiber, microfibril/nanofibril cellulose (MFCs/NFCs), and micro/nanocrystalline cellulose (MCCs/NCCs) are adapted for different biomedical applications. This short review provides a general characteristic of plant-based cellulose (PC) and its potential to be applied in biomedical fields such as tissue engineering.

“…Citric acid (CA) is a small organic acid molecule that has been widely used in the food and pharmaceutical industries 14 and it exists in its citrate form in fresh wet bone. 15 Several studies have demonstrated that the CA positively influenced the growth of HA on various substrates immersed in simulated body fluid (SBF) such as chitosan, 16 cellulose, 17 lignocellulosic fibres, 18 elastin-like recombinamers 19 and collagen membrane. 20 Furthermore, it was described that the inclusion of CA during the preparation of sol-gel HA resulted in high bioactivity in SBF.…”

This work reports the modification of freeze/thaw poly(vinyl alcohol) hydrogel using citric acid as the bioactive molecule for hydroxyapatite formation in simulated body fluid. Inclusion of 1.3 mM citric acid into the poly(vinyl alcohol) hydrogel showed that the mechanical strength, crystalline phase, functional groups and swelling ability were still intact. Adding citric acid at higher concentrations (1.8 and 2.3 mM), however, resulted in physically poor hydrogels. Presence of 1.3 mM of citric acid showed the growth of porous hydroxyapatite crystals on the poly(vinyl alcohol) surface just after one day of immersion in simulated body fluid. Meanwhile, a fully covered apatite layer on the poly(vinyl alcohol) surface plus the evidence of apatite forming within the hydrogel were observed after soaking for seven days. Gel strength of the soaked poly(vinyl alcohol)/citric acid-1.3 mM hydrogel revealed that the load resistance was enhanced compared to that of the neat poly(vinyl alcohol) hydrogel. This facile method of inducing rapid growth of hydroxyapatite on the hydrogel surface as well as within the hydrogel network can be useful for guided bone regenerative materials.

Natural fibers are lightweight, cost‐effective, readily available, and eco‐friendly materials. However, natural fiber‐reinforced composites are constrained by biological inconsistency and inferior fiber‐matrix interfacial properties, which restrict effective processing using advanced additive manufacturing methods. In this study, we develop a novel concept for natural fiber composite interfaces by growing hydroxyapatite (HAP) nanocrystals on jute fibers. The resulting hybrid composite is characterized using mechanical testing, nanoindentation, and modulus mapping. The interfacial region suggests a 31.4% increase in stiffness and possesses a storage modulus of up to 7.5 GPa. The tensile modulus and strength of the hybrid composite improves by 30% and 33%, respectively. Furthermore, we develop a novel process for the additive manufacturing of jute fiber thermoset composites through a direct writing (DW) process. The HAP modification increases thermal conductivity, consequently improving the curing process during DW and enhancing composite manufacturability. We demonstrate that the DW process enables the printing of intricate multilayer geometries with varying fiber content.Highlights Hydroxyapatite is used for natural fiber composite interfacial modification. Nanoindentation shows the interfacial region exhibits 31.4% higher stiffness. Modified composites possess superior mechanical performance. Jute fibers are thermally functionalized for composite additive manufacturing. A direct writing method is developed for continuous functionalized jute fiber.
