Abstract
Albumin is derived from blood plasma and is the most abundant protein in blood plasma, which has good mechanical properties, biocompatibility and degradability, so albumin is an ideal biomaterial for biomedical applications, and drug-carriers based on albumin can better reduce the cytotoxicity of drug. Currently, there are numerous reviews summarizing the research progress on drug-loaded albumin molecules or nanoparticles. In comparison, the study of albumin-based hydrogels is a relatively small area of research, and few articles have systematically summarized the research progress of albumin-based hydrogels, especially for drug delivery and tissue engineering. Thus, this review summarizes the functional features and preparation methods of albumin-based hydrogels, different types of albumin-based hydrogels and their applications in antitumor drugs, tissue regeneration engineering, etc. Also, potential directions for future research on albumin-based hydrogels are discussed.

Abstract
BACKGROUND Enzymes are efficient biocatalysis that catalysis a large number of reactions due to their chemical, regional, or stereo specifities and selectivity. Their usage in bioreactor or biosensor systems has great importance. Carbonic anhydrase enzyme catalyzes the interconversion between carbon dioxide and water and the dissociated ions of carbonic acid. In organisms, the carbonic anhydrase enzyme has crucial roles connected with pH and CO2 homeostasis, respiration, and transport of CO2/bicarbonate, etc. So, immobilization of the enzyme is important in stabilizing the catalyst against thermal and chemical denaturation in bioreactor systems when compared to the free enzyme that is unstable at high temperatures and extreme pH values, as well as in the presence of organic solvents or toxic reagents. Nano-scale composite materials have attracted considerable attention in recent years, and electrospinning based all-nanocomposite materials have a wide range of applications. In this study, electrospun nanofibers were fabricated and used for the supporting media for carbonic anhydrase enzyme immobilization to enhance the enzyme storage and usage facilities. OBJECTIVE In this article, our motivation is to obtain attractive electrospun support for carbonic anhydrase enzyme immobilization to enhance the enzyme reusability and storage ability in biocatalysis applications. METHODS In this article, we propose electrospun nanofibers for carbonic anhydrase carrying support for achieving our aforementioned object. In the first part of the study, agar with polyacrylonitrile (PAN) nanofibers was directly fabricated from an agar-PAN mixture solution using the electrospinning method, and fabricated nanofibers were cross-linked via glutaraldehyde (GA). The morphology, chemical structure, and stability of the electrospun nanofibers were characterized. In the second part of the study, the carbonic anhydrase enzyme was immobilized onto fabricated electrospun nanofibers. Then, enzyme activity, the parameters that affect enzyme immobilization such as pH, enzyme amount, immobilization time, etc. and reusability were investigated. RESULTS When the scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) analysis results are combined in the characterization process of the synthesized electrospun nanofibers, the optimum cross-linking time is found to be 8 hours using 5% glutaraldehyde cross-linking agent. Then, thermal stability measurements showed that the thermal stability of electrospun nanofibers has an excellent characteristic for biomedical applications. The optimum temperature value was found 37°C, pH 8 was determined as an optimum pH, and 100 ppm carbonic anhydrase enzyme concentration was found to be optimum enzyme concentration for the carbonic anhydrase enzyme immobilization. According to the kinetic data, carbonic anhydrase immobilized electrospun nanofibers acted as a biocatalyst in the conversion of the substrate to the product in 83.98%, and immobilized carbonic anhydrase enzyme is reusable up to 9 cycles in biocatalysis applications. CONCLUSION After applying the framework, we get a new biocatalysis application platform for carbonic anhydrase enzyme. Electrospun nanofibers were chosen as the support material for enzyme immobilization. By using this approach, the carbonic anhydrase enzyme could easily be used in the industrial area by cost-effective advantageous aspects.

Abstract
It is well known that the extracellular matrix (ECM) plays a vital role in the growth, survival
and differentiation of cells. Though two-dimensional (2D) materials are generally used as substrates for
the standard in vitro experiments, their mechanical, structural, and compositional characteristics can
alter cell functions drastically. Many scientists reported that cells behave more natively when cultured
in three-dimensional (3D) environments than on 2D substrates, due to the more in vivo-like 3D cell
culture environment that can better mimic the biochemical and mechanical properties of the ECM. In
this regard, water-swollen network polymer-based materials called hydrogels are highly attractive for
developing 3D ECM analogs due to their biocompatibility and hydrophilicity. Since hydrogels can be
tuned and altered systematically, these materials can function actively in a defined culture medium to
support long-term self-renewal of various cells. The physico-chemical and biological properties of the
materials used for developing hydrogel should be tunable in accordance with culture needs. Various
types of hydrogels derived either from natural or synthetic origins are currently being used for cell culture
applications. In this review, we present an overview of various hydrogels based on natural polymers
that can be used for cell culture, irrespective of types of applications. We also explain how each
hydrogel is made, its source, pros and cons in biological applications with a special focus on regenerative
engineering.

Abstract
Arginase, isolated from beef liver, apyrase and glutaminase, isolated from Escherichia coli, were immobilized during the synthesis of a hydrogel matrix made from poly(ethylene glycol) (PEG) and bovine serum albumin (BSA). After synthesis, a one- to three-fold increase in the K m values was observed for the enzymes. The apparent K m were 30 mM of arginine, 6.5 mM of glutamine, and 52 μM of ATP for immobilized arginase, glutaminase, and apyrase, respectively. In general, immobilization allowed the enzymes to retain most of their initial activity; after incubating for 1 month at 37°C in the presence of the respective substrates, more than 95% of the initial activity was found. The optimal temperatures varied from 40 to 60°C for all enzyme preparations. The immobilized arginase, glutaminase, and apyrase had optimal activity over a larger pH range which was due to the matrix effect. Surface modification of arginase with 5,000 Mw methoxy-PEG increased the stability for up to 24 days (incubated at 37°C) compared to eight days for the native enzyme tested under the same conditions. However, this modification did not affect the stability of glutaminase.

Abstract
This article describes a new way to immobilize an enzyme by enzymatic hydrogelation to facilitate catalysis in the organic solvent to attain high activity and stability. A self-immobilized acid phosphatase (AP) in a molecular hydrogel created by the enzymatic hydrogelation had shown higher activities in several organic solvents than those of free AP in the same solvents. The high activities of AP(gel) in organic solvents are mainly due to the cooperative effect of the amphiphilic nanofibers in the hydrogel and the phase transfer between the organic solvent and the water in the hydrogel. This approach provides a useful method to immobilize enzymes for biotransformation in organic solvents.

Abstract
When silk fiber derived from Bombyx mori was subjected to degumming treatments twice in water and subsequent degraded processing in slightly alkaline aqueous solution under high-temperature and high-pressure, the water-soluble silk sericin peptides (SS) with different molecular mass from 10 to 70 kDa were obtained. The sericin peptides could be conjugated covalently with insulin alone with cross-linking reagent glutaraldehyde. The physicochemical properties of the silk sericin-insulin (SS-Ins) conjugates were determined by Enzyme-Linked Immunosorbent Assay (ELISA). The biological activities of SS-Ins bioconjugates were investigated in vitro and in vivo. The results in human serum in vitro indicated that the half-life of the synthesized SS-Ins derivatives was 2.3 and 2.7 times more than that of bovine serum albumin-insulin (BSA-Ins) conjugates and intact insulin, respectively. The pharmacological activity of SS-Ins bioconjugates lengthened to 21 h in mice in vivo, which was over 4 times longer than that of the native insulin. The immunogenicity of silk sericin and the antigenicity of SS-Ins derivatives were not observed in both rabbits and mice. The bioconjugation of insulin with silk sericin protein evidently improved both physicochemical and biological stability of the polypeptide.

Abstract
Polyketone polymer -[-CO-CH(2)-CH(2)-](n)-, obtained by copolymerization of ethene and carbon monoxide, is utilized for immobilization of three different enzymes, one peroxidase from horseradish (HRP) and two amine oxidases, from bovine serum (BSAO) and lentil seedlings (LSAO). The easy immobilization procedure is carried out in diluted buffer, at pH 7.0 and 3 degrees C, gently mixing the proteins with the polymer. No bifunctional reagents and spacer arms are required for the immobilization, which occurs exclusively via a large number of hydrogen bonds between the carbonyl groups of the polymer and the -NH groups of the polypeptidic chain. Experiments demonstrate a high linking capacity of polymer for BSAO and an extraordinary strong linkage for LSAO. Moreover, activity measurements demonstrate that immobilized LSAO totally retains the catalytic characteristics of the free enzyme, where only a limited increase of K(M) value is observed. Finally, the HRP-activated polymer is successfully used as active packed bed of an enzymatic reactor for continuous flow conversion and flow injection analysis of hydrogen peroxide containing solutions.

Abstract
A block copolymer, (short-chain alginate)-co-MPEG, was synthesized and used for coating the capsular membranes of the photosensitive microcapsules. The resulted microcapsules exhibited an excellent mechanical strength. The permeability test results revealed that the capsular membrane was freely permeable to cytochrome C and myoglobin, less permeable to serum albumin, and almost impermeable to IgG. In the cell attachment test, the results showed that the surface formed by (short-chain alginate)-co-MPEG copolymer could effectively reduce cell adhesion as compared to poly(L-lysine) and alginate. The microcapsules were evaluated by intraperitoneal implantation experiment of mice. The results demonstrated that microcapsules coated with (short-chain alginate)-co-MPEG were more biocompatible than the conventional alginate/PLL/alginate microcapsules.

Abstract
It seems likely, and indeed inevitable, that medical device usage will continue its rapid increase over the next 10 to 20 years and beyond. For surgeons, these new inventions will come in many forms but should take into account biocompatibility and resistance to encrustations and to microorganisms. This review focuses on research under way at present in vitro and in vivo on materials and coatings, use of bioelectrics, use of artificial organs and tissues, application of indigenous bacteria, and other alternative device management techniques, which could well become part of clinical practice in the future. By necessity, some of these citations are speculative, but supporting documentation for their inclusion is presented.
