Abstract
In proteomic studies, selective enrichment of target phosphoproteins from biological samples is of importance. Of various enrichment methods, affinity chromatography is widely preferred method. Development of micro-affinity columns with simple strategies are in constant demand. Here in this report, for the first time, we have embedded TiO2 particles within the monolith structure in a single step. Fourier transform infrared spectroscopy and scanning electron microscope analysis has confirmed the successful incorporation of TiO2 particles within the polymer monolith. Incorporation of 3-(trimethoxy silyl) propyl methacrylate within the poly(hydroxyethyl methacrylate) based monolith composition has enhanced its rigidity and one fold phosphoprotein (α-casein) adsorption capacity. Presence of only 66.6 µg of TiO2 particles within the monolith has displayed a four-fold higher affinity to α-casein over the non-phosphoprotein i.e. bovine serum albumin. Under optimized conditions (TiO2 particle and acrylate silane), the affinity monolith has a maximum adsorption capacity of ∼ 72 mg per gram monolith. Translation of TiO2 particles-monolith into a microcolumn of 3 cm long and 19 µL volume was successful. α-casein was selectively separated from an artificial protein mixture of α-casein and BSA, α-casein spiked human plasma, and cow milk within 7 min.

Abstract
Microfluidics is the technology or system wherein the behavior of fluids' is studied onto a miniaturized device composed of chambers and tunnels. In biological and biomedical sciences, microfluidic technology/system or device serves as an ultra-high-output approach capable of detecting and separating the biomolecules present even in trace quantities. Given the essential role of protein, the identification and quantification of proteins help understand the various living systems' biological function regulation. Microfluidics has enormous potential to enable biological investigation at the cellular and molecular level and maybe a fair substitution of the sophisticated instruments/equipment used for proteomics, genomics, and metabolomics analysis. The current advancement in microfluidic systems' development is achieving momentum and opening new avenues in developing innovative and hybrid methodologies/technologies. This chapter attempts to expound the micro/nanofluidic systems/devices for their wide-ranging application to detect and separate protein. It covers microfluidic chip electrophoresis, microchip gel electrophoresis, and nanofluidic systems as protein separation systems, while methods such as spectrophotometric, mass spectrometry, electrochemical detection, magneto-resistive sensors and dynamic light scattering (DLS) are discussed as proteins' detection system.

Abstract
SCOPE Milk-proteins, besides lactose, stimulate insulin and incretin secretion. Although whey-proteins (WP) are more efficient than casein (Cas) in hormone secretion, the effects of reversal of the (WP/Cas) ratio in whole-milk are poorly known. METHODS AND RESULTS Healthy volunteers received two different cow-milk drinks, at identical lactose (0.36 g × kg-1 BW) and total-protein (0.18 g × kg1 BW) loads, but at reversed WP/Cas ratio. One is cow-whole milk with a ≈20/80 [WP/Cas] ratio, the other an experimental cow-milk with a ≈70/30 [WP/Cas] ratio ([↑WP↓Cas]-milk). Both milk-types induced the same mild hyperglycemic response. Following [↑WP↓Cas]-milk, the [20'-90'] insulin incremental area (iAUC) (+ ≈44%, p < 0.035), and the [20'-120'] C-peptide iAUC (+ ≈47%, p < 0.015) are greater than those with cow-milk. Similarly, following [↑WP↓Cas]-milk, the GLP-1 [20'-90'] iAUC (+96%, p < 0.025), and the GIP [30'-60'] iAUC (+140%, p < 0.006), were greater than those with cow-milk. Plasma total and branched-chain amino acids are also greater following the [↑WP↓Cas] than cow-milk. CONCLUSIONS Reversal of the (WP/Cas) ratio in cow-milk enhanced the insulin response, an effect possibly mediated by incretins and/or amino acids(s). These data may be useful in designing specific milk formulas with different effects on insulin and incretin response(s).

Abstract
PDMS-based multichannel microfluidic chip was designed and fabricated in a simple approach using readily available tools. UV-initiated in situ polymerization of poly(2-hydroxy ethyl methacrylate-co-di(ethylene glycol) diacrylate-co-N,N'-diallyl l-tartardiamide) in an Eppendorf tube was achieved within 40 min. This polymerization process was successfully translated to a microfluidic chip format without any further modifications. Iminodiacetic acid was successfully immobilized on aldehyde functional monoliths via Schiff base reaction and confirmed by FT-IR spectroscopy. Four transition metal ions (Co (II), Zn (II), Ni (II), and Cu (II)) were chelated individually on four IDA-monolith microfluidic chips. The conjoint metal-ion monolith microfluidic chip has displayed high permeability (9.40 × 10-13 m2 ) and a porosity of 32.8%. This affinity microfluidic chip has pre-fractioned four human plasma proteins (fibrinogen, immunoglobulin, transferrin, and human serum albumin) based on their surface-exposed histidine surface topography. A protein recovery of approximately 95% (Bradford assay data) was achieved. The multimonolith microchip can be reusable even after three protein adsorption-desorption cycles.

Incorporation of silver stearate nanoparticles in methacrylate polymeric monoliths for hemeprotein isolation. OPEN CHEM 2020.

Abstract
AbstractA unique method was used to synthesize extremely stable silver stearate nanoparticles
(AgStNPs) incorporated in an organic-based monolith. The facile strategy was then
used to selectively isolate hemeproteins, myoglobin (Myo) and hemoglobin (Hb). Ethyl
alcohol, silver nitrate, and stearic acid were, respectively, utilized as reducing
agents, silver precursors, and capping agents. The color changed to cloudy from
transparent, indicating that AgStNPs had been formed. AgStNP nanostructures were then
distinctly integrated into the natural polymeric scaffold. To characterize the
AgStNP–methacrylate polymeric monolith and the silver nanoparticles,
energy-dispersive X-ray (EDX), scanning electron microscopy (SEM), and
Fourier-transform infrared (FT-IR) spectroscopy were used. The results of the SEM
analysis indicated that the AgStNP–methacrylate polymeric monolith’s
texture was so rough in comparison with that of the methacrylate polymeric monolith,
indicating that the extraction process of the monolith materials would be more
efficient because of the extended surface area of the absorbent. The comparison
between the FT-IR spectra of AgStNPs, the bare organic monolith, and
AgStNP–methacrylate polymeric monolith confirms that the AgStNPs were
immobilized on the surface of the organic monolith. The EDX profile of the built
materials indicated an advanced peak of the Ag sequence which represented an Ag atom
of 3.27%. The results therefore established that the AgStNPs had been successfully
integrated into the monolithic materials. Extraction efficiencies of 92% and 97% were
used to, respectively, recover preconcentrated Myo and Hb. An uncomplicated method is
a unique approach of both fabrication and utilization of the nanosorbent to
selectively isolate hemeproteins. The process can further be implemented by using
other noble metals.

Polycarbonate Microchip Containing CuBTC-Monopol Monolith for Solid-Phase Extraction of Dyes. Int J Anal Chem 2020; 2020:8548927. [PMID: 32095138 PMCID: PMC7036109 DOI: 10.1155/2020/8548927] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2019] [Revised: 12/07/2019] [Accepted: 12/10/2019] [Indexed: 12/27/2022] Open
Abstract
In the present study, preparation of CuBTC-monopol monoliths for use within the microchip solid phase extraction was undertaken through a 20-min UV lamp-assisted polymerization for 2,2-dimethoxy-2-phenyl acetophenone (DMPA), butyl methacrylate (BMA), and ethylene dimethacrylate (EDMA) alongside inclusion of the porogenic solvent system (1-propanol and methanol (1 : 1)). The resultant coating underwent coating using CuBTC nanocrystals in ethanolic solution of ethanolic solution of 1,3,5-benzenetricarboxylic acid (H3BTC, 10 mM) and 10 mM copper(II) acetate Cu(CH3COO)2. This paper reports enhanced extraction, characterization, and synthesis studies for porous CuBTC metal organic frameworks that are marked by different methods including SEM/EDAX analysis, atomic force microscopy (AFM), and Fourier-transform infrared spectroscopy (FT-IR). The evaluation of the microchip's performance was undertaken as sorbent through retrieval of six toxic dyes (anionic and cationic dyes). Various parameters (desorption and extraction step flow rates, volume of desorption solvent, volume of sample, and type of desorption solvent) were examined to optimize dye extraction using fabricated microchips. The result indicated that CuBTC-monopol monoliths were permeable with the ability of removing impurities and attained high toxic dye extraction recovery (83.4-99.9%). The assessment of reproducibility for chip-to-chip was undertaken by computing the relative standard deviations (RSDs) of the six dyes in extraction. The interbatch and intrabatch RSDs ranged between 3.8 and 6.9% and 2.3 and 4.8%. Such features showed that fabricated CuBTC-monopol monolithic disk polycarbonate microchips have the potential of extracting toxic dyes that could be utilized for treating wastewater.

Abstract
Background:
In recent times many new uses have been found for nanomaterials that have
undergone homogenous immobilization within porous supports. For this paper, immobilization of
SNPs on a thiol-functionalized silica monolith using a fast, easy, environmentally friendly and costeffective
process was performed. This was achieved by modifying the surface of a silica-based
monolith using thiol groups, and then we fabricated green SNPs in situ, reducing an inorganic precursor
silver nitrate solution (AgNO3) by employing tangerine peel extract as a reducing reagent,
with Ag-thiol bonds forming along the monument. Doing this allows monoliths to be prepared in
such a way that, as TEM analysis demonstrated, SNPs are evenly distributed along the rod's length.
Once the materials had been fabricated, they were employed as a sorbent by being placed in a centrifuge.
The SNP-thiol functionalized silica monolith was then tested using a standard protein (HSA).
Methods:
The process involves creating monolithic materials by employing a two-part sol-gel technique
before modifying the surface of the silica-based monolith using thiol groups for hosting purposes.
Homogenous surface coverage was achieved through the use of a non-toxic "green" reducing
reagent (tangerine peel extract) to reduce a silver nitrate solution in place to create SNPs joined to the
pore surface of a thiol-functionalized silica monolith, employing bonds of Ag-thiol. Once these materials
were synthesized, they were classified by utilizing a number of methods based on SEM coupled
with EDAX, TEM, AFM and BET analysis. The silica-based monolith, embedded with constructed
SNPs, was employed as a sorbent in the preconcentration of human serum albumin (HSA).
Results:
The performance of the fabricated materials was measured against a silica-based monolith
with no SNPs. Also, a silica monolith with constructed SNPs embedded was employed to capture
HSA within a sample of human urine mixed with a double detergent concentrate (SDS). Such a
monolith containing functionalized SNPs can be a highly effective sorbent for preconcentration of
proteins in complex samples.
Conclusion:
It was shown to have superior performance compared to a bare silica-based monolith.
Additionally, it was shown that a monolithic column modified by SNPs could preconcentrate spiked
HSA in urine samples.

Abstract
Boronate affinity chromatography (BAC) is argued to be a critical tool in specific capture and separation of cis-diol containing compounds. In present study, organic boronate affinity monolith poly(3-acrylamido phenylboronic acid-co-ethylene dimethacrylate) (AAPBA-co-EDMA) is prepared through one-step in situ polymerization procedure within a micropipette through the application of a pre-polymerization mixture which contains functional monomer (3-acrylamido phenylboronic acid), cross-linker (ethylene dimethacrylate), porogenic solvent (methanol with poly ethylene glycol) and initiator (2,2-dimethoxy-2-phenyl-acetophenone). Following the optimization of time exposure to UV lamp with 365 nm, the macroporous organic boronate monolith was selected. Several approaches including SEM and BET analysis, FT-IR spectroscopy and measuring contact angle were applied in the characterization of the morphology of the monolith. Several cis-diol compounds that include catechol and galactose are applied in the assessment of the boronate affinity of the organic monolithic material. Additionally, the capture of glucose from urine sample is also conducted. The basic principle of the
approach is that boronic acid forms covalent bond with cis-diols in basic solutions whereas the ester bonds are dissociated under acidic media. By using the study results, monolith demonstrate good selectivity towards cis-diol containing compounds. Due to the hydrophilic property of monolith, the affinity chromatography monolith can be performed for several cis-diol compounds including glycoproteins and nucleosides. Also, fabrication of the organic boronate monolithic in microfluidic equipment is essential in facilitating the extraction of boronate affinity using small-volume samples.

Abstract
Lab-on-a-Chip (LoC), or micro-Total Analysis Systems (μTAS), is recognized as a powerful analytical technology with high capabilities, though end-user products for protein purification are still far from being available on the market. Remarkable progress has been achieved in the separation of nucleic acids and proteins using electrophoretic microfluidic devices, while pintsize devices have been developed for protein isolation according to miniaturized chromatography principles (size, charge, affinity, etc.). In this work, we review the latest advances in the fabrication of components, detection methods and commercial implementation for the separation of biological macromolecules based on microfluidic systems, with some critical remarks on the perspectives of their future development towards standardized microfluidic systems and protocols. An outlook on the current needs and future applications is also presented.

Abstract
Determination of proteins and peptides is among the main challenges of today's bioanalytical chemistry. The application of microchip technology in this field is an exhaustively developed concept that aims to create integrated and fully automated analytical devices able to quantify or detect one or several proteins from a complex matrix. Selective extraction and preconcentration of targeted proteins and peptides especially from biological fluids is of the highest importance for a successful realization of these microsystems. Incorporation of solid structures or supports is a convenient solution employed to face these demands. This review presents a critical view on the latest achievements in sample processing techniques for protein determination using solid supports in microfluidics. The study covers the period from 2006 to 2015 and focuses mainly on the strategies based on microbeads, monolithic materials and membranes. Less common approaches are also briefly discussed. The reviewed literature suggests future trends which are discussed in the concluding remarks.
