“…Along with materials, several preparation and deposition techniques for biomaterials have been reported in recent years. [ 23,24 ] Electrospinning is one of the effective synthesis techniques that can create 1D‐biomaterial‐based fibers (electrospun mats) at the nano‐ and microscales. [ 25 ] Such kinds of 1D nanofibers (NFs) provide excellent charge transport properties, which are beneficial to get an excellent RS effect from the switching layer.…”

In the present work, resistive switching (RS) devices are fabricated using naturally abundant, nontoxic, biocompatible, and biodegradable biomaterials. For this purpose, one‐dimensional (1D) chitosan nanofibers (NFs), collagen NFs, and chitosan‐collagen NFs are synthesized by using an electrospinning technique. Among different NFs, the collagen NFs‐based device shows promising RS characteristics. In particular, the optimized Ag/Collagen NFs/FTO RS device shows a voltage‐tunable analog memory behavior and good non‐volatile memory properties. Moreover, it can also mimic various biological synaptic learning properties and can be used for pattern classification applications with the help of the Spiking Neural Network (SNN). The time series analysis technique is employed to model and predict the switching variations of the RS device. Moreover, the collagen NFs have shown good cytotoxicity and anticancer properties, suggesting excellent biocompatibility as a switching layer. The biocompatibility of collagen NFs is explored with the help of NRK‐52E (rat kidney normal cell line) and MCF‐7 (cancer cell line). Additionally, the biodegradability of the device is evaluated through a physical transient test. This work provides a vital step towards developing a biocompatible and biodegradable switching material for sustainable non‐volatile memory and neuromorphic computing applications.This article is protected by copyright.

“…Significant advancements have been achieved in the development of new biocompatible materials by using surface modification techniques. [14][15][16][17][18] Although many of these modifications demonstrated improvements in the biological performance of the implant materials, some of the resulting coatings possess several inherent disadvantageous properties. Delamination or diffusion of particles from the surface has been reported for coatings with a non-covalent character after long-term use.…”

Aging society demands advanced bone implants that can achieve long‐term success through osseointegration at the bone‐implant interface. Polyetheretherketone (PEEK), a bioinert implant material, often struggles with connecting to existing bone tissue, leading to inflammation and implant replacement. Following nature's lessons, a new strategy is introduced that masks the surface of bio‐ and chemically inert Polyetheretherketone implants with a covalently anchored bone‐mimetic surface. This method transforms PEEK into a bone‐integrative material by grafting a ≈300 nm thick gelatin layer onto its surface, subsequently mineralized with calcium phosphate. Herein, it is showed that this surface modification for implant materials combines excellent bulk implant properties with the characteristic structure and functional properties of natural bone. In vitro biocompatibility assays, employing NIH‐3T3 fibroblast and MC3T3‐E1 osteoblast cell lines, confirm the enhanced biocompatibility of the modified material. This strategy offers promising prospects for improving bone implants and exemplifies the adaptation of a non‐osseointegrative material to a bone‐like interface.

“…They prevent bone anchorage failure and delay revision surgery [48][49][50][51][52]. Several methods can be used to produce calcium phosphate coatings on metallic bone implants including plasma spraying, magnetron sputtering, pulsed laser deposition, electrospray deposition, electrophoretic deposition, biomimetic deposition, a sol-gel process combined with dip or spin coating, electrodeposition, and hydrothermal synthesis [53]. Among them, plasma spraying is the main industrial process, extensively used since the 1970s to coat metallic bone implants [54].…”

This review deals with the design of bioactive calcium phosphate coatings deposited on metallic substrates to produce bone implants. The bioceramic coating properties are used to create a strong bonding between the bone implants and the surrounding bone tissue. They provide a fast response after implantation and increase the lifespan of the implant in the body environment. The first part of the article describes the different compounds belonging to the calcium phosphate family and their main properties for applications in biomaterials science. The calcium-to-phosphorus atomic ratio (Ca/P)at. and the solubility (Ks) of these compounds define their behavior in a physiological environment. Hydroxyapatite is the gold standard among calcium phosphate materials, but other chemical compositions/stoichiometries have also been studied for their interesting properties. The second part reviews the most common deposition processes to produce bioactive calcium phosphate coatings for bone implant applications. The last part describes key physicochemical properties of calcium phosphate coatings and their impact on the bioactivity and performance of bone implants in a physiological environment.
