“…[109][110][111][112] Models that exist for interfacial protein adlayers that define appropriate heterogeneity parameters for subsequent cell adhesion/spreading are very important. 113 Future efforts will incorporate the influence of interfacial heterogeneity in protein adsorption studies. Characterization of its influence on the mediation of subsequent reactions at the interface is urgently required, not only to provide novel physical insights into the adsorption process but also to provide a more realistic picture of the events occurring in body fluid.…”

When biomaterials are implanted into an animal body, the body fluid proteins initially adsorb and then cells recognize these surfaces. Adherent cell functions respond differently to diverse biomaterial surfaces with different properties. Thus, an understanding of cellular responses to biomaterials is crucial for effective control of biomaterial − cell interactions. I have researched how to clarify interfacial phenomena via protein adsorption and subsequent cell adhesion to hydroxyapatite nanocrystals using a quartz crystal microbalance with a dissipation technique. In this review, I focused on the current understanding of enhanced biocompatibility by exploring the roles of protein mediation at the interface. The most promising nano-bio interfaces are explained, and different protein adsorption and cell adhesion processes are highlighted depending on their interfacial states. This approach will clarify several ambiguities of interfacial phenomena between biomaterials and cells and will help in the design of novel biomaterials that can be implanted.

Several of the over 200 known species of Agave L. are currently used for production of distilled beverages and biopolymers. The plants live in a wide range of stressful environments as a result of their resistance to abiotic stress (drought, salinity, and extreme temperature) and pathogens, which gives the genus potential for germplasm conservation and biotechnological applications that may minimize economic losses as a result of the global climate change. However, the limited knowledge in the genus of genome structure and organization hampers development of potential improved biotechnological applications by means of genetic manipulation and biocatalysis. We reviewed Agave and plant sequences in the GenBank NCBI database for identifying genes with biotechnological potential for fermentation, bioenergy, fiber improvement, and in vivo plant biopolymer production. Three-dimensional modeling of enzyme structures in plant accessions revealed structural differences in sucrose 1-fructosyltransferase, fructan 1-fructosyltransferase, fructan exohydrolase (1-FEH), cellulose synthase (CES), and glucanases (EGases) with possible effects in fructan, sugar, and biopolymer production. Although the coding genes of FEH and enzymes involved in biopolymer production (CES, sucrose synthase, and EGases) remain unidentified in Agave L., our results could aid isolation of such genes in Agave. By comparing nucleotide and amino acid sequences in accessions of Agave and other plants, knowledge may be gained about transcriptional regulation and enzymatic activity factors. Future study is needed of biotechnological application of Agave genes for crop breeding aided by genetic engineering and biocatalysis.

“…The hydrogels made of pure cellulose are known in difficulty because of less solubility in common organic solvents. The cellulose‐based hydrogel is originated from lignocellulosic biomass such as sugarcane, agave tequilana, and bamboo . The hydrogel is composed of cellulose, hemicellulose, and lignin strongly bonded by non‐covalent cross linkages.…”

“…Therefore, CSH is an alternative biomass source for the preparation of cellulose‐based hydrogel. The cellulose‐based hydrogels prepared by phase inversion process can be fabricated from cellulose solution through physically coagulation of cellulose fibers. This is due to the fact that the abundant hydroxyl groups of cellulose form linkage network by hydrogen bond .…”

Recently, cellulose-based hydrogel nanocomposite materials have been attracted increasing attention owing to their potential applications in different areas including medical, electrical, optical, and magnetic fields. This is due to the fact that cellulose is one of the most abundant resources and possesses several unique properties required in medical fields, whereas silica nanoparticles (nSiO 2 ) play an important role in developing materials with high functionality. In this study, cottonseed hull (CSH) was used as a source of cellulose and nSiO 2 was used to prepare hydrogel nanocomposite films via phase inversion method without chemical crosslinking agent of cellulose. CSH was first pre-treated with sodium hydroxide (NaOH) and sodium hypochlorite (NaOCl) for delignification and bleaching, respectively. The pre-treated CSH exhibited whiter fiber and lower amount of lignin as compared with the untreated CSH. The properties of cellulose-base hydrogel were found to be improved as a result of the addition of nSiO 2 at 2-6 wt % for tensile strength and up to 10 wt % for modulus and elastic modulus (G 0 ). However, the elongation at break was decreased with the incorporation of nSiO 2 . Moreover, the TEM images displayed the nano-grape structure of nSiO 2 surrounded by cellulose molecules.
