[PMID: 37351669 PMCID: PMC10386930 DOI: 10.1007/s00216-023-04798-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 06/07/2023] [Accepted: 06/09/2023] [Indexed: 06/24/2023]
Abstract
Silica nanospheres (SNS) were grown on the inner walls of silica capillaries through a dynamic in situ nucleation process to prepare a highly porous and large accessible surface area substrate. The SNS were then functionalized with octadecyl (C18), 3-aminopropyltriethoxysilane (APTES), beta-cyclodextrin (β-CD), and amino groups to develop robust and efficient chromatographic stationary phases. The modified silica capillaries were exploited for open-tubular liquid chromatography (OT-LC) and open-tubular capillary electrochromatography (OT-CEC) applications. The prepared stationary phases were compared to conventional capillaries in terms of separation performance. The synthesis process was optimized, and the bonded-phase stationary phases were characterized by the electron microscopy technique. The effects of different solvents, additives, and functional groups on the geometry and chromatographic resolving power of the SNS were envisaged. The capillaries modified with octadecyl groups were evaluated for the separation of non-steroidal anti-inflammatory drugs, phenones, alkenylbenzenes, and enantiomers of chlorophenoxy herbicides. As an application instance, an SNS-C18-coated capillary was utilized for the separation of alkenylbenzenes from clove extract and protein digest medium, through OT-LC and OT-CEC techniques, respectively. The β-CD functionalized capillary was applied for the OT-CEC separation of a dichlorprop racemic mixture.

Abstract
Stimuli-responsive block copolymers have exhibited their feasibility for drug delivery and analysis of biomolecules. However, study of the electrophoretic behavior of antibiotics by open tubular capillary electrochromatography (OT-CEC) based on smart block copolymers coatings is still a substantial challenge. Herein, we reported an OT-CEC protocol for analysis of cephalosporin antibiotics with pH-responsive block copolymers as coatings. By using the reversible addition-fragmentation chain-transfers radical polymerisation technique, the smart poly(styrene-maleic anhydride-acrylic acid) (P(St-MAn-AA)) was synthesized and subsequently chemical bonded onto the inner walls of amino-grafted capillaries. The pH induced changes in the stretch/curl states of P(St-MAn-AA) chains were used to generate an adjustable hydrophobic/hydrophilic interaction and hydrogen bonds between the polymer coatings and the analytes. The OT-CEC performance was evaluated by varying the monomer ratios, polymer coating amounts and layers, buffer concentrations and pH values. Baseline separation of the three-test antibiotics was achieved at pH 8.0. The proposed OT-CEC technique was further applied to the determination of rat serum antibiotics in the metabolic processes. The present work demonstrates an enhancement in antibiotics separation efficiency, and shows a great potential for the preparation of stimuli-responsive block copolymers coatings and in OT-CEC analysis of real samples in living bio-systems.

Abstract
Enantioseparation of chiral products has become increasingly important in a large diversity of academic and industrial applications. The separation of chiral compounds is inherently challenging and thus requires a suitable analytical technique that can achieve high resolution and sensitivity. In this context, CE has shown remarkable results so far. Chiral CE offers an orthogonal enantioselectivity and is typically considered less costly than chromatographic techniques, since only minute amounts of chiral selectors are needed. Several CE approaches have been developed for chiral analysis, including chiral EKC and chiral CEC. Enantioseparations by EKC benefit from the wide variety of possible pseudostationary phases that can be employed. Chiral CEC, on the other hand, combines chromatographic separation principles with the bulk fluid movement of CE, benefitting from reduced band broadening as compared to pressure-driven systems. Although UV detection is conventionally used for these approaches, MS can also be considered. CE-MS represents a promising alternative due to the increased sensitivity and selectivity, enabling the chiral analysis of complex samples. The potential contamination of the MS ion source in EKC-MS can be overcome using partial-filling and counter-migration techniques. However, chiral analysis using monolithic and open-tubular CEC-MS awaits additional method validation and a dedicated commercial interface. Further efforts in chiral CE are expected toward the improvement of existing techniques, the development of novel pseudostationary phases, and establishing the use of chiral ionic liquids, molecular imprinted polymers, and metal-organic frameworks. These developments will certainly foster the adoption of CE(-MS) as a well-established technique in routine chiral analysis.

Abstract
The development of separation methods for the analysis and resolution of chiral drugs and solutes has been an area of ongoing interest in pharmaceutical research. The use of proteins as chiral binding agents in high-performance liquid chromatography (HPLC) has been an approach that has received particular attention in such work. This report provides an overview of proteins that have been used as binding agents to create chiral stationary phases (CSPs) and in the use of chromatographic methods to study these materials and protein-based chiral separations. The supports and methods that have been employed to prepare protein-based CSPs will also be discussed and compared. Specific types of CSPs that are considered include those that employ serum transport proteins (e.g., human serum albumin, bovine serum albumin, and alpha1-acid glycoprotein), enzymes (e.g., penicillin G acylase, cellobiohydrolases, and α-chymotrypsin) or other types of proteins (e.g., ovomucoid, antibodies, and avidin or streptavidin). The properties and applications for each type of protein and CSP will also be discussed in terms of their use in chromatography and chiral separations.

Abstract
Coatings are necessary to prevent protein and peptide adsorption to the capillary surface and obtain high intermediate precision. In this protocol, we first present our basic strategy to address peptide separation using three different coatings: one neutral and two cationic coatings, the latter largely differing in their induced electroosmotic mobility. In detail, we will describe how we apply the statically adsorbed coatings to obtain very high plate numbers and high repeatability.With some model examples, we clearly describe the scope of the method for the analysis of peptide samples: tryptic digests are addressed as well as small glycoproteins and glycopeptides largely differing in their effective electrophoretic mobility. We also show that the method is suitable for a fast screening of peptide samples despite a high matrix load comprising of up to 500 mmol/L sodium chloride. We demonstrate that this basic CE-MS method is rather independent of the polarity of the analytes with a very fast near-baseline separation of very hydrophobic Aβ peptides related to the onset of Alzheimer's disease. These examples will give an impression, which coating is most suitable for a specific analytical application.Special attention is paid to difficult aspects of the coating procedure and the CE-MS method, e.g., the potential of cross-contamination when changing the coatings.

Abstract
A novel non-instrumental bioanalysis based on colloidal-gold immunochromatography in a modified glass capillary was developed and named capillary immunochromatographic assay (CICA). In this report, glass capillary was proposed as a support in immunochromatographic assay because of its excellent characteristics. Goat anti-rabbit IgG and parvalbumin (PV) were immobilized on the inner wall of the glass capillary as control zone and test zone, respectively. The CICA was constructed, and main variables for the performance were optimized. Using an important allergen of fish products (parvalbumin, PV) as the target, the analytical efficiency of the developed technique was investigated and the visual detection limit (VDL) and semi-quantitative limit of detection (LOD) were estimated to be 70 ng mL(-1) and 40 ng mL(-1), respectively. The coefficient of variation (CV) for the intra-assay and inter-assay was calculated for the PV concentration of 50 ng mL(-1), and the entire operation, including sample preparation, was consistently performed in 30 min. The developed technique was implemented and validated with different foodstuffs, including Scophthalmus maximus (Linnaeus), surimi products, and livestock, confirming sufficient accuracy and precision of results and verifying the method to be efficacious. These results enabled us to propose CICA as a new and promising technique for simple, rapid, and on-site screening of PV in biological samples.

Abstract
Capillary electrophoresis (CE) methods using proteins as the chiral selectors have been developed for the separation of enantiomeric mixtures. For chiral separations in protein-based CE, two methods were utilized. One is affinity capillary electrochromatography (ACEC), and the other is affinity CE (ACE). This chapter deals with the advantages and disadvantages of ACEC and ACE. Furthermore, enantioseparations utilizing ACEC based on packed α(1)-acid glycoprotein-immobilized silica gels, immobilized avidin to fused silica capillaries and ACE based on penicillin G-acylase dissolved in the running buffer are described in detail.

Abstract
The screening of ligands against proteins plays important role in drug discovery and biological research. Using a dye labelled Streptavidin binding aptamer (SBA) as a competitive reporter probe, we found that adenosine bound to streptavidin specifically. Fluorescence spectral analysis showed that adenosine bound to both avidin and streptavidin with the K(ds) in the range of 0.1-0.2 mM, and these bindings can be blocked by biotin. Although streptavidin and avidin are well-known and widely used in bioanalysis, their biological role is still a riddle so far. Since adenosine is a ubiquitous physiological regulator present in cells, our finding provides new clues for the understanding of the functions of both proteins.

Abstract
Since its development in the early 1970s, CEC has been studied quite extensively, but unfortunately its use is still mostly located at an academic level. Reasons for this are the limited availability of commercially available stationary phases (SPs) and columns, along with some practical limitations, such as column fragility, lack of column robustness and reproducibility. Nevertheless, CEC maintains a place among the separation techniques, probably because of its unique feature to combine two separation principles. Also in the field of chiral separations, CEC is often used as a separation technique and already showed its potential for this kind of analyses. This overview will focus on the recent applications, i.e. between 2006 and 2010, in enantioselective analysis by means of CEC. For the selected applications, the used SPs (chiral selectors) and their potential for future method development or screening purposes will be evaluated and critically discussed.

Abstract
The finding of melatonin, the often called "hormone of darkness" in plants opens an interesting perspective associated to the plethora of health benefits related to the moderate consumption of red wine. In this study, the implementation of a new method for the determination of melatonin in complex food matrices by CEC with immobilized carboxylic multi-walled carbon nanotubes as stationary phase is demonstrated. The results indicated high electrochromatographic resolution, good capillary efficiencies and improved sensitivity respect to those obtained with conventional capillaries. In addition, it was demonstrated highly reproducible results between runs, days and columns. The LOD for melatonin was 0.01 ng/mL. The method was successfully applied to the determination of melatonin in red and white wine, grape skin and plant extracts of Salvia officinalis L.

Abstract
The present review intends to summarize recent developments in the field of enantioselective separations and analysis by CEC. It covers studies published in English language in common peer-reviewed journals within the period between 2003 and 2006. Both, methods making use of chiral mobile phase additives as well as chiral stationary phases for electrochromatographic enantiomer separations, are reviewed. Achievements that have been made on the various column technologies, such as open-tubular, particle-packed, inorganic, organic and particle-fixed (hybrid-type) monolithic as well as molecularly imprinted polymer phases, are discussed.

Abstract
Avidin and streptavidin are widely used in (strept)avidin-biotin technology, which is based on their tight biotin-binding capability. These techniques are exceptionally diverse, ranging from simple purification and labeling methods to sophisticated drug pre-targeting and nanostructure-building approaches. Improvements in protein engineering have provided new possibilities to develop tailored protein tools. The (strept)avidin scaffold has been engineered to extend the existing range of applications and to develop new ones. Modifications to (strept)avidins--such as simple amino acid substitutions to reduce biotin binding and alter physico-chemical characters--have recently developed into more sophisticated changes, including chimeric (strept)avidins, topology rearrangements and stitching of non-natural amino acids into the active sites. In this review, we highlight the current status in genetically engineered (strept)avidins and illustrate their versatility as advanced tools in the multiple fields of modern bioscience, medicine and nanotechnology.

Abstract
To overcome several problems in affinity capillary electrophoresis (ACE), i.e., low detectability, need for sample derivatization, and difficulty in the fixation of affinity ligands (ALs), multifunctional magnetic particles (MFMPs) were prepared by immobilizing both fluorescent molecules and ALs for low-density lipoproteins onto the surface of magnetic polymer microspheres with a polyelectrolyte multilayer coating technique and applied to the ACE analysis. The prepared MFMPs showed a remarkable change in the electrophoretic mobility (mu ep) by the addition of low-density lipoproteins (LDL), whereas for high-density lipoproteins (HDL), mu ep of the MFMPs kept constant, so that it was confirmed that the MFMPs possess an affinity with LDL. On the other hand, the MFMPs can be trapped by the magnetic field even under a higher electric field for electrophoresis. By a successive on-off control of the magnetic field, online preconcentration of the LDL bound MFMPs and the selective separation of LDL from HDL were successfully achieved. In the ACE analysis of LDL employing UV detection, an 82-fold increase in the sensitivity was obtained by the on-capillary sample preconcentration using the MFMPs. When laser induced-fluorescence detection was employed, furthermore, the limit of detection for LDL was improved to the order of subpicomolar.

Abstract
In capillary electrochromatography (CEC), magnetic particles (MPs) were packed in a fused silica capillary by using the magnetic field to be retained without frits. For a chiral CEC separation, avidin was immobilized onto the surface of the MPs (AVI-MPs) as a stationary phase by using the physical adsorption technique. The injected AVI-MPs into the capillary were stably captured with the magnet (surface magnetic flux density, 250 mT) under the separation voltage of 10 kV (190 V/cm). By employing the fritless AVI-MPs packed capillary, the chiral separation of ketoprofen was successfully attained with the packing length of only 5 cm. Effects of the modification condition of avidin, pH of background solution, and the packing length on the enantioseparation were also investigated. Under the optimal condition, furthermore, the repeatability for the retention time of ketoprofen was better than 1.5% in the relative standard deviation and the capillary-to-capillary reproducibility was also acceptable in the prepared fritless capillaries.
