... The printed auricular constructs have high elasticity, high printing accuracy, and low swelling ratio, which can mimic the microenvironment for cartilage regeneration. Wang et al. established a one-step strategy to integrate the GelMA microgel fabrication and assembly through vat photopolymerization in situ using DLP bioprinting [132]. Although bioprinting is appealing for building tissue mimics, precise positioning control of mini-tissue blocks (i.e., spheroids) in 3D space remains challenging. ...
Three-dimensional (3D) bioprinting has emerged as a groundbreaking technology for fabricating intricate and functional tissue constructs. Central to this technology are the bioinks, which provide structural support and mimic the extracellular environment, which is crucial for cellular executive function. This review summarizes the latest developments in microparticulate inks for 3D bioprinting and presents their inherent challenges. We categorize micro-particulate materials, including polymeric microparticles, tissue-derived microparticles, and bioactive inorganic microparticles, and introduce the microparticle ink formulations, including granular microparticles inks consisting of densely packed microparticles and composite microparticle inks comprising microparticles and interstitial matrix. The formulations of these microparticle inks are also delved into highlighting their capabilities as modular entities in 3D bioprinting. Finally, existing challenges and prospective research trajectories for advancing the design of microparticle inks for bioprinting are discussed.
Natural biomolecules with excellent biocompatibility, degradability, and the ability to guide effective tissue regeneration are considered ideal materials for constructing tissue engineering hydrogel scaffolds. The employing of 3D printing technology facilitates the preparation of natural biomolecular‐based scaffold for specific morphological requirements for tissue engineering. However, there are significant limitations in the precise manufacturing of such scaffolds using extrusion‐based 3D printing technology. In this review, we put forward the challenges encountered in the 3D printing process using natural biomolecular inks. Building upon this, we summarize and discuss strategies commonly employed to enhance the printing performance of natural biomolecular inks, including inducing rapid ink cross‐linking, improving ink rheological properties, incorporating auxiliary inks for shaping, flexibly controlling ink extrusion, and optimizing printing equipment. Furthermore, this review offers a perspective on the future design and development of printing technologies based on natural biomolecular inks.
Microporous hydrogels have been utilized in an unprecedented manner in the last few decades, combining materials science, biology, and medicine. Their microporous structure makes them suitable for wide applications, especially as cell carriers in tissue engineering and regenerative medicine. Microporous hydrogel scaffolds provide spatial and platform support for cell growth and proliferation, which can promote cell growth, migration, and differentiation, influencing tissue repair and regeneration. This review gives an overview of recent developments in the fabrication techniques and applications of microporous hydrogels. The fabrication of microporous hydrogels can be classified into two distinct categories: fabrication of non‐injectable microporous hydrogels including freeze‐drying microporous method, two‐phase sacrificial strategy, 3D biofabrication technology, etc., and fabrication of injectable microporous hydrogels mainly including microgel assembly. Then, the biomedical applications of microporous hydrogels in cell carriers for tissue engineering, including but not limited to bone regeneration, nerve regeneration, vascular regeneration, and muscle regeneration are emphasized. Additionally, the ongoing and foreseeable applications and current limitations of microporous hydrogels in biomedical engineering are illustrated. Through stimulating innovative ideas, the present review paves new avenues for expanding the application of microporous hydrogels in tissue engineering.
Silica nanoparticles-embedded smart-gels are efficient drug carrier systems due to their structural flexibility, high porosity, and ease of formulation development. Herein, the extent of interaction of minoxidil (MXD), a potent vasodilator prodrug, with silica nanoparticles (SiNPs) and alginate (ALG) was investigated. The SiNPs were prepared by extracted silica from rice husk ash and these SiNPs were further used to prepare MXD-loaded-SiNPs (MXD-SiNPs) by loading with an appropriate amount of MXD. The as-prepared MXD-SiNPs were encapsulated in ALG polymer by freeze-gelation method and evaluated by various characterization techniques. The amorphous nature of the SiNPs was confirmed by XRD examination, while the nature of physical interaction and encapsulation of the drug in the SiNPs and ALG gel was examined by FTIR analysis. TEM analysis revealed that the MXD-SiNPs had a monodisperse collection of spherical nanoparticles, while the particle size (~150 nm) of as-prepared formulation was determined from DLS studies. The drug entrapment efficiency was 86% and the loading efficiency was 22%. The as-developed MXD-SiNPs@ALG gel formulation exhibited sustained release over 12 h compared to pure MXD and MXD-SiNPs. These results suggest that the newly developed formulation has several advantageous properties that make it suitable for cutaneous administration of the drug.
All‐aqueous phase separation systems play essential roles in bioanalytical and biochemical applications. Compared to conventional oil and organic solvent‐based systems, these systems are characterized by their rich bulk and interfacial properties, offering superior biocompatibility. In particular, phase separation in all‐aqueous systems facilitates the creation of compartments with specific physicochemical properties, and therefore largely enhances the accessibility of the systems. In addition, the all‐aqueous compartments have diverse affinities, with an important property known as partitioning, which can concentrate (bio)molecules toward distinct immiscible phases. This partitioning affinity imparts all‐aqueous interfaces with selective permeability, enabling the controlled enrichment of target (bio)molecules. This review introduces the basic principles and applications of partitioning‐induced interfacial phenomena in a typical all‐aqueous system, namely aqueous two‐phase systems (ATPSs); these applications include interfacial chemical reactions, bioprinting, and assembly, as well as bio‐sensing and detection. The primary challenges associated with designing all‐aqueous phase separation systems and several future directions are also discussed, such as the stabilization of aqueous interfaces, the handling of low‐volume samples, and exploration of suitable ATPSs compositions with the efficient protocol.
Using aqueous two-phase systems (ATPSs) for three-dimensional (3D) printed complex structures has attracted considerable attention in the field of biomedicine. In this study, we present an unusual approach to constructing reconfigurable 3D printed structures within an aqueous environment. Inspired by biological systems, we introduce both specific and nonspecific interactions to anchor functionalized nanoparticles to the water-water interface, thereby imparting adaptive dual locks of structural integrity and permeability to the 3D printed liquid structures. Using state-of-the-art in situ liquid-liquid interfacial atomic force microscopy imaging, we successfully demonstrate various morphologies of interfacial films formed at the ATPS interface. In addition, by incorporating d -glucose or sodium alginate into the systems, the dual locks can be easily manipulated. Our study paves a pathway for 3D printing multiresponsive all-aqueous systems with controllable structures and permeability, showing promising implications for the development of smart drug delivery systems and in vivo reactions.
