Surface interaction at the biomaterial–cell interface is essential for a variety of cellular functions, such as adhesion, proliferation, and differentiation. Nevertheless, changes in the biointerface enable to trigger specific cell signaling and result in different cellular responses. In order to manufacture biomaterials with higher functionality, biomaterials containing immobilized bioactive ligands have been widely introduced and employed for tissue engineering and regenerative medicine applications. Moreover, a number of physical and chemical strategies have been used to improve the functionality of biomaterials and specifically at the material interface. Here, the interactions between materials and cells at the interface levels are described. Then, the importance of surface properties in cell function is discussed and recent methods for surface modifications are systematically highlighted. Additionally, the impact of bulk material properties on the cellular responses is briefly reviewed.

“…Yan et al found that p-phenylenediamine functionalized CQDs substantially improved Young’s modulus of SF-PLA scaffold (1610 kPa), which was higher than that of SF-PLA scaffold (466 kPa) [ 49 ]. Notably, the size of the nanoparticles can alter the mechanical properties of the tissue engineering scaffold [ 11 ]. A research group of Safaie et al provided a comprehensive study to determine the influence of CQDs with different sizes on the mechanical strength of resulting CDs blended polypropylene (PP) fiber.…”

“…An appropriate solution for the enhanced cellular phenomena would be designing tissue engineering constructs with suitable physicochemical, mechanical, and biological properties. Over the years, various tissue engineering constructs such as film, sponge, membrane, fiber, hydrogel, and 3D ink scaffold have been developed by many researchers to achieve success in tissue regeneration [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. The biocompatible scaffolds closely mimic the three-dimensional (3D) architecture of native tissue, aiding cellular events such as attachment, proliferation, and differentiation [ 15 , 16 ].…”

“…[ 17 , 18 , 19 ]. The scaffolds of natural polymer provide higher biocompatibility and lower mechanical strength, whereas synthetic polymer-based scaffolds show enhanced mechanical strength with lower biocompatibility and biodegradability [ 11 , 14 , 16 , 19 , 20 ]. Hence, the researchers integrate both natural and synthetic polymers at the composition to mitigate the above problems [ 21 , 22 , 23 ].…”

Regeneration of damaged tissues or organs is one of the significant challenges in tissue engineering and regenerative medicine. Many researchers have fabricated various scaffolds to accelerate the tissue regeneration process. However, most of the scaffolds are limited in clinical trials due to scaffold inconsistency, non-biodegradability, and lack of non-invasive techniques to monitor tissue regeneration after implantation. Recently, carbon dots (CDs) mediated fluorescent scaffolds are widely explored for the application of image-guided tissue engineering due to their controlled architecture, light-emitting ability, higher chemical and photostability, excellent biocompatibility, and biodegradability. In this review, we provide an overview of the recent advancement of CDs in terms of their different synthesis methods, tunable physicochemical, mechanical, and optical properties, and their application in tissue engineering. Finally, this review concludes the further research directions that can be explored to apply CDs in tissue engineering.

“…[7] In spite of the growing efforts in various fields, the synthesis of nanoparticles of desired size, shape and controlled monodispersity is still not routinely achieved. Traditionally, gold and other metal nanoparticles can be successfully synthesized by a wide range of physical and chemical methods [8] such as microwave irradiation, [9] aerosol technique, [10] ultraviolet radiation, [11] laser ablation [12] and photochemical reduction. [13] Although these techniques resulted in nanoparticles with high mono-dispersity, such process remains technically complex, involving expensive and hazardous raw materials.…”

Here, we report an eco-friendly, benign and rapid mycogenic synthesis of gold nanoparticles of various shapes using cell-free extract of the fungus Bipolaris oryzae (B. oryzae). Three different volumes of cell-free extract of the fungus were exposed to an aqueous solution of gold chloride and in all three cases, there is a gradual color change from light yellow to pink indicating the formation of gold nanoparticle. Reduced nicotinamide adenine dinucleotide phosphate (NADPH) dependent enzyme present in the cell-free extract of the fungus B. oryzae leads to the rapid reduction of Au 3 + to Au 0 within 5-10 min when incubated with an aqueous solution of gold chloride. UV-visible and fourier transform infra red (FTIR) spectroscopy measurements show the presence of aminoacids, such as tyrosine/ phenylalanine and proteins as the possible capping agent. High-resolution transmission electron microscopy (HR-TEM) revealed the morphology of the structures were anisotropic triangles, hexagons, decahedrals and isotropic spheres. Isotropic spherical nanoparticles and anisotropic nanoparticles such as triangles, hexagons and decahedrals were produced at higher and lower volumes of the fungal extract, respectively. Rapid and sustainable approach for the production of gold nanoparticles of various shapes such as the one reported has a plethora of applications in the field of life-sciences and medicine.
