Abstract
Isolation or enrichment of biological molecules from complex biological samples is mostly a prerequisite in proteomics, genomics, and glycomics. Different techniques have been used to advance the efficiency of the purification of biological molecules. Bioaffinity chromatography is one of the most powerful technique that plays an important role in the isolation of target biological molecules by the specific interactions with ligands that are immobilized on different support materials. This review examines the recent developments in bioaffinity chromatography particularly over the past 5 years in the literature. Also properties of supports, immobilization techniques, types of binding agents, and methods used in bioaffinity chromatography applications are summarized.

Abstract
This study describes the technological processes and characteristics of biomass direct combustion power generation, biomass gasification power generation, biomass mixed combustion power generation, and biomass biogas power generation in terms of their importance and application in China. Under the perspective of environmental and economic sustainability, the life cycle assessment (LCA) method and dynamic analysis method based on time value are used to simulate and evaluate the environmental loads and economic benefits of different power generation processes. By comparing with coal-fired power generation systems, the environmental and economic benefits of different biomass power generation technologies are illustrated. The results shows that biomass gasification power generation has the best environmental benefits, with a total load of 1.05 × 10−5, followed by biomass biogas power generation (9.21 × 10−5), biomass direct combustion power generation (1.23 × 10−4), and biomass mixed combustion power generation (3.88 × 10−4). Compared with the environmental load of coal-fired power generation, the reduction rate was 97.69%, 79.69%, 72.87%, and 14.56% respectively. According to the analysis of the technical economy evaluation results, when the dynamic pay-back period and IRR (internal rate of return) were used as evaluation indicators, the biomass direct combustion power generation has the best pay-back period (7.71 years) and IRR (19.16%), followed by the biogas power generation, with higher dynamic payback period (12.03 years), and lower IRR (13.49%). For gasification power generation and mixed-combustion power generation, their dynamic payback period is long, and the IRR is low. If net present value (NPV) is selected as the evaluation index, the biogas power generation appears to be the best because its net present value per megawatt is 11.94 million yuan, followed by direct combustion power generation (6.09 million yuan), and the net present value of mixed-combustion power generation and gasification power generation is relatively low. Compared with coal-fired power generation, direct combustion power generation and biogas power generation present significant economic benefits.

Isolation of RNA and beta-NAD by phenylboronic acid functionalized, monodisperse-porous silica microspheres as sorbent in batch and microfluidic boronate affinity systems. Colloids Surf B Biointerfaces 2018; 174:333-342.

Abstract
Monodisperse-porous silica microspheres 5.5 μm in size were obtained by a staged shape templated hydrolysis-condensation method, with a bimodal pore-size distribution. 3-aminophenylboronic acid (APBA) was covalently attached onto the silica microspheres with a capacity of 0.476 mmol APBA/g microspheres. The boronate affinity isolation behaviour of ribonucleic acid (RNA) containing cis-diol at 3'-end was investigated by using APBA attached-silica microspheres as the sorbent in batch fashion. A short-chain diol carrying agent, β-nicotinamide adenine dinucleotide (β-NAD) was used as a target molecule with stronger affinity for phenylboronic acid ligand. The maximum equilibrium adsorptions for RNA and β-NAD were determined as 60 and 159 mg/g sorbent, respectively. By using the synthesized sorbent, phosphate buffer at pH 7.0 containing sorbitol was successfuly used as a mild elution medium for obtaining quantitative desorptions with both RNA and β-NAD. RNA isolations from mammalian and bacterial cells were successfully performed while protecting the structural integrity of RNA via boronate affinity interaction in batch fashion. A microfluidic boronate affinity system including a microcolumn 300 μm in diameter was also constructed using APBA attached-silica microspheres as the stationary phase. The breakthrough curves of microfluidic system were obtained by studying with different feed concentrations of RNA and β-NAD. Quantitative desorptions and satisfactory isolation yields were obtained with RNA and β-NAD in the microfluidic system. The proposed system is useful for boronate affinity applications in genomics or proteomics in which valuable cis-diols at low concentrations are recovered from low-volume samples.

Abstract
Aminophenyl boronic acid (APBA) modified hydrogel beads were prepared as a new sorbent for nucleotide isolation. Spherical hydrogel beads, obtained by suspension copolymerization, were the base material for the sorbent. The carboxyl groups on the gel bead surface were activated with a water soluble carbodiimide, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC). APBA was then covalently attached to the activated structure via the amine groups. The maximum APBA attached to the gel was 34mg/g. The reversible adsorption-desorption behavior of β-nicotinamide adenine dinucleotide (β-NAD) was investigated by using 3.5 and 34mg/g of APBA on the hydrogel beads. The equilibrium -NAD adsorption capacities for these beads were determined as approximately 25 and 100mg/g, respectively. The -NAD absorption capacity of these APBA beads is significantly greater than similar supports.

Abstract
Magnetic iron oxide nanoparticles functionalized with 4-carboxyphenylboronic acid (CPBA-MNPs) were developed for extracting genomic DNA, total RNA and nucleic acids from seeds. The seed samples were genetically-modified maize seeds and unmodified soybean seeds infected by bean pod mottle virus and tobacco ringspot virus. The total nucleic acids, genomic DNA, and RNA could be separately extracted from these seeds with high qualities using CPBA-MNPs under different conditions. Furthermore, the results of real-time quantitative qPCR and real-time reverse transcription (RT)-PCR indicated that the nucleic acids extracted from these seeds using CPBA-MNPs were suitable for the detection of genetically-modified seeds and seed-borne viruses.

Abstract
Bioelectronic interfaces that establish electrical communication between redox enzymes and electrodes have potential applications as biosensors, biocatalytic reactors, and biological fuel cells. However, these interfaces contain labile components, including enzymes and cofactors, which have limited lifetimes and must be replaced periodically to allow long-term operation. Current methods to fabricate bioelectronic interfaces do not allow facile replacement of these components, thus limiting the useful lifetime of the interfaces. In this paper we describe a versatile new fabrication approach that binds the enzymes and cofactors using reversible ionic interactions. This approach allows the interface to be removed via a simple pH change and then replaced to fully regenerate the biocatalytic activity. The positively charged polyelectrolyte poly(ethylenimine) was used to ionically bond a dehydrogenase enzyme and its cofactor to a gold electrode that was functionalized with 3-mercaptopropionic acid and the electron mediator toluidine blue O. By reducing the pH, the surface-bound 3-mercaptopropionic acid was protonated, disrupting the ionic bonds and releasing the enzyme-modified polyelectrolyte. After neutralization, fresh enzyme and cofactor were bound, regenerating the bioelectronic interface. Cyclic voltammetry, chronoamperometry, constant potential amperometry, electrochemical impedance spectroscopy, and Fourier transform infrared spectroscopy analyses were used to characterize the bioelectronic interfaces. For the two enzymes tested (secondary alcohol dehydrogenase and sorbitol dehydrogenase) and their respective cofactors (beta-nicotinamide adenine dinucleotide phosphate and beta-nicotinamide adenine dinucleotide), the reconstituted interface exhibited a surface coverage, an electron-transfer coefficient, and a turnover rate similar to those of the original interface.

Abstract
Bioelectronic interfaces that allow dehydrogenase enzymes to communicate with electrodes have potential applications such as biosensors and biocatalytic reactors. A major challenge in creation of such bioelectronic interfaces is to orient the enzyme, its cofactor, and an electron mediator properly with respect to the electrode in order to achieve efficient, multistep electron transfer. This paper describes a versatile, new method that uses cysteine, an inexpensive, branched amino acid having sulfhydryl, amino, and carboxyl functional groups, to achieve such orientation. This approach provides greater flexibility in assembling complex bioelectronic interfaces than previously reported approaches that bind the enzyme, cofactor, and mediator in a linear chain. Cysteine was attached to a gold electrode through the sulfhydryl groups, to the electron mediator toluidine blue O (TBO) through the carboxyl group, and to the cofactor (e.g., NAD(P)+) through the amino group. Cyclic voltammetry, impedance spectroscopy, chronoamperometry and quartz crystal microbalance gravimetry were used to demonstrate the sequential assembly steps and the electrical activity of the resulting bioelectronic interface.

Abstract
In this study, nucleotide adsorption-desorption behaviour of boronic acid-carrying uniform, porous particles was investigated. The particles were produced by a "multi-step microsuspension polymerization" in the form of poly(styrene-vinylphenyl boronic acid-divinylbenzene) terpolymer. In the first step of the production method, uniform polystyrene latex particles (6.2 microm in size) were obtained by dispersion polymerization. These particles were first swollen by a low molecular mass organic agent (i.e. dibutylphthalate, DBP) and then by a monomer mixture including styrene (S), 4-vinylphenyl boronic acid (VPBA) and divinylbenzene (DVB). The particle uniformity was protected in both swelling stages by adjusting DBP/polystyrene latex and monomer mixture/polystyrene latex ratios. Polymerization of the monomer mixture in the swollen seed particles provided boronic acid-carrying uniform, porous particles 11-12 microm in size. To have uniform particles with different porosities and boronic acid contents, the feed concentration of boronic acid-carrying monomer and the monomer/seed latex ratio were changed. The particles were tried as sorbent for the adsorption of a model nucleotide (i.e., beta-nicotinamide adenine dinucleotide, beta-NAD). In the beta-NAD adsorption experiments, the maximum equilibrium adsorption was obtained at pH 8.5 which was very close to pKa of boronic acid. The incorporation of boronic acid functionality provided a significant increase in the beta-NAD adsorption. In contrast to plain poly(styrene-co-divinylbenzene) particles, four-fold higher beta-NAD adsorption was obtained with the boronic acid functionalized particles. Beta-NAD was desorbed from the particles with the yields higher than 90% by weight.

Abstract
Molecular recognition sites for the nucleotides adenosine 5'-monophosphate (1), guanosine 5'-monophosphate (2), cytosine 5'-monophosphate (3), and uridine 5'-monophosphate (4) are imprinted in an acrylamide-acrylamidephenylboronic acid copolymer (5) membrane. The imprinted membranes are assembled on piezoelectric Au quartz crystals or Au electrodes via electropolymerization or on the gate surface of an ISFET device by radical polymerization. The imprinted membranes reveal selectivity toward the imprinted nucleotide, and the association of the respective nucleotides with the recognition sites is transduced by the following: (i) microgravimetric, quartz crystal microbalance (QCM) measurements; (ii) Faradaic impedance analyses, and (iii) potentiometric responses of the ISFET devices. While the microgravimetric QCM measurements reflect the swelling of the polymers upon the association of the nucleotides with the recognition sites, the ISFET response is due to the charging of the polymer membrane as a result of the formation of the nucleotide-boronate complex. The selective detection of the nucleotides may lead to new DNA/RNA sequencing methods. Also, specific recognition sites for beta-D(+)-glucose (6), D(+)-galactose (7), and beta-D(-)-fructose (8) were imprinted in an acrylamide-acrylamidephenylboronic acid copolymer (5) membrane associated with an ISFET device. Selective sensing of the respective monosaccharides is accomplished in the presence of the imprinted membrane-functionalized ISFET devices.
