Abstract
Bio-based and biodegradable materials play a vital role in a sustainable and green economy. These materials must exhibit properties that are similar to or better than the properties of oil- or coal-based materials and require sophisticated synthesis technologies and detailed knowledge of structure-property correlations. For comprehensive molecular structure elucidation, advanced analytical methods, including coupled and hyphenated techniques that combine advanced fractionation and information-rich spectroscopic detectors, are an indispensable tool. One important tool for fractionating complex polymers regarding molecular size is size exclusion chromatography. For fractionating polymers with regard to chemical composition, solvent (or temperature) gradient HPLC has been developed. The combination of different liquid chromatography methods in comprehensive two-dimensional HPLC setups is another important tool. Today, a toolbox of HPLC methods is in place that enables the fractionation of complex bio-based and biodegradable polymers according to the most important molecular parameters including molecular size, composition, functionality, and branching. Here, an overview of the different techniques and some major applications is presented. Some representative developments in the field are discussed, and different techniques, experimental protocols, and applications are highlighted.

Abstract
BACKGROUND Hyaluronic acid (HA) has gained significant attention due to its unique physical, chemical, and biological properties, making it widely used in various industries. This study aimed to screen bacterial isolates for HA production, characterize favorable fermentation conditions, and evaluate the inhibitory effect of bacterial HA on cancer cell lines. RESULTS A total of 108 bacterial isolates from diverse sources were screened for HA production using HPLC, turbidimetric, and carbazole determination methods. Among the HA-producing isolates, Klebsiella pneumoniae H15 isolated from an animal feces sample, was superior in HA production. The strain was characterized based on its morphological, cultural, and biochemical characteristics. Molecular identification using 16S rDNA sequencing and phylogenetic analysis confirmed its identity. Fermentation conditions, including pH, temperature, time, and agitation rate, were optimized to maximize HA production. The basal medium, comprising sucrose (7.0%) as carbon source and combined yeast extract with peptone (1.25% each) as nitrogen substrate, favored the highest HA production at pH 8.0, for 30 h, at 30 °C, under shaking at 180 rpm. The average maximized HA concentration reached 1.5 g L-1. Furthermore, bacterial HA exhibited a significant inhibitory effect on three cancer cell lines (MCF-7, HepG-2 and HCT), with the lowest concentration ranging from 0.98-3.91 µg mL-1. CONCLUSIONS K. pneumoniae H15, isolated from animal feces demonstrated promising potential for HA production. The most favorable fermentation conditions led to a high HA production. The inhibitory effect of bacterial HA on cancer cell lines highlights its potential therapeutic applications. These findings contribute to a broader understanding and utilization of HA in various industries and therapeutic applications.

Abstract
In recent years, cancerous cases have increased remarkably worldwide, and metastasis is the leading cause of death. Therefore, research on the early detection of cancer and metastasis has expanded to aid successful cancer treatment. Here in this paper, at the first step, an electrospun nanofibrous membrane (NFM) with a core-shell structure was fabricated from PCL and HA to achieve cancer cell capturing (about 75% of cells). On the other hand, hyaluronic acid (HA)-functionalized graphene quantum dots (GQDs) were used to detect captured cancer cells on NFM through the changes in photoluminescence intensity. Therefore, CD44 receptor-HA interaction is the main principle used for both entrapment and detection of cancer cells. Results demonstrated the GQD-HA fluorescent intensity of solution decreased through the increase of the captured cancer cell numbers on NFM, which is related to the more adsorption of GQD nanocomposites to the CD44 receptors. In contrast, this intensity for noncancerous cells was steady with any cell concentrations. This difference shows the system's remarkable selectivity and specificity, which can be crucial in fluorescent imaging for accurate cancer diagnosis.

Screening of the Chemical Composition and Identification of Hyaluronic Acid in Food Supplements by Fractionation and Fourier-Transform Infrared Spectroscopy. Polymers (Basel) 2021; 13:polym13224002.

Abstract
Hyaluronic acid, together with collagen, vitamins or plant extracts, is a part of many cosmetic and food preparations. For example, this polysaccharide is used in formulation of many food supplements due to its protective effects on human health. In this work, the screening of the chemical composition of three chosen dietary supplements (powder, tablets and capsules) containing hyaluronic acid was carried out using Fourier-transform infrared spectroscopy. Because of the low amount of analyte in all these samples, it was isolated or concentrated prior to the analysis using a suitable sequential fractionation protocol. Individual isolation procedures were established for each sample based on their declared composition. Firstly, the major components such as collagen or vitamins were removed to obtain polysaccharide fractions by the enzymatic treatment and/or washing out with the appropriate solvents. In some cases, the water insoluble part was removed from the rest dissolved in water. Then, hyaluronic acid was precipitated with copper(II) cations and thus separated from the other polysaccharides. Finally, the analyte was identified in the enriched fractions by the characteristic vibrational bands. The amount of hyaluronic acid in the purified fractions was determined in three ways: gravimetrically, spectrophotometrically, and using isotachophoresis. The combination of the appropriate preparative and analytical steps led to the successful evaluation of chemical composition, finding and quantification of hyaluronic acid in all the studied samples.

Abstract
Nowadays, the use of nanoparticle-based drug delivery systems has received much more attention. In this regard, here, graphene quantum dots (GQD) were used as drug carriers as well as imaging agents for cancer cells. In order to optimize the dose of the drug and reduce its side effects for healthy cells, hyaluronic acid was decorated on the surface of GQD to target cancer cells. The morphology and size of the synthesized nanoparticles alone and conjugated with hyaluronic acid were investigated using scanning electron microscopy (SEM) and transmission electron microscopy (TEM); TEM images revealed a particles size of ∼5.67 and ∼8.69 nm, respectively. In the presence of 1-ethyl-3-[3(dimethylamino)propyl]carbodiimide hydrochloride/N-hydroxysuccinimide (EDC/NHS), hyaluronic acid was bounded to dopamine hydrochloride and was prepared to react with GQD. After synthesis of graphene quantum dot-hyaluronic acid nanocomposite, curcumin (CUR) as a drug model was loaded on the synthesized nanocarriers, and its loading percentage was measured. The results showed that 98.02% of the drug was loaded on the nanocarriers. Also, the conjugation of each agent on the nanocarrier was approved by photoluminescence spectroscopy, Fourier transform infrared spectroscopy (FTIR), and UV-visible absorption techniques, and the results showed that the reactions were performed correctly. The effect of GQD, graphene quantum dot-hyaluronic acid, CUR, graphene quantum dot-hyaluronic acid-CUR on the viability of HeLa and L929 cells was evaluated by the MTT test. The results showed that the synthesized nanocarrier is completely biocompatible, and the drug nanocarriers reduce HeLa cell viability significantly due to the mediation of hyaluronic acid-CD44 for drug cell uptake. Simultaneously with drug delivery, the other goal of these nanocarriers is to image cancer cells by emitting fluorescent light. Fluorescent microscopy showed that these nanocarriers were adsorbed on HeLa cells, unlike L929 cells.

Abstract
Background:Sodium hyaluronate (NaHA) is generally supplemented in products related to contact lenses for increasing comfort during wearing. The quantity of sodium hyaluronate and the material of lenses affect the retention of sodium hyaluronate on the contact lenses.Methods:We developed a convenient and sensitive but unconventional chromatographic method to quantify sodium hyaluronate and analyze its release behavior from contact lenses. The reverse-phase chromatography eluted sodium hyaluronate with high molecular masses in the shortest time and could separate salt and small compounds from sodium hyaluronate.Results:This method could accurately quantify sodium hyaluronate with diverse molecular sizes. Because sodium hyaluronate was eluted in a narrow time frame, sensitivity was significantly enhanced, and the limit of detection of this method was 0.45 μg/mL. According to this quantitation method, the attached quantity of sodium hyaluronate is related to the water content of the material. Furthermore, a material test indicated that the release efficiency of sodium hyaluronate depends on the material of lenses. Nonionic Polymacon had a longer half-life in the sodium hyaluronate release curve than negative Methafilcon A and silicone hydrogel.Conclusion:This hyaluronate quantification method is a fast, sensitive and accurate method, making it suitable for the in vitro hyaluronate research without further derivatization.

Abstract
Collagen and hyaluronic acid (HA) are biopolymers that affect the appearance and condition of the skin. Delivery of these compounds into the skin is highly challenging since have a number of disadvantageous properties, such as high molecular weight and hydrophilicity. Here, we evaluated the transdermal penetration of low and high molecular weight collagen and HA from microemulsions. A number of microemulsion formulations, differing in the content of polymers and surfactants (i.e. penetration promoters), were used for the permeation study. In addition, a correlation was made between the composition of these microemulsions and the polymers transport efficiency. The results indicate that, microemulsions enable transdermal permeation of collagen and HA. The concentration of polymers and the solubilization capacity of microemulsions had the greatest influence on the permeation. Surprisingly, the molecular weight of polymers and the content of other components affected the size of microemulsion particles, and thus these parameters had an indirect influence on the permeation process. This study demonstrated therefore the potential therapeutic use of microemulsion with collagen and HA in improving and regenerating the barrier of aged or diseased skin.

Abstract
Capillary electrophoresis with large-volume sample stacking using an electroosmotic flow pump was developed for the determination of chondroitin sulfate, dermatan sulfate, and hyaluronic acid. Central composite design was used to simultaneously optimize the parameters for capillary electrophoresis separation. The optimized capillary electrophoresis conditions were 200 mM sodium dihydrogen phosphate, 200 mM butylamine, and 0.5% w/v polyethylene glycol as a background electrolyte, pH 4 and -16 kV. Exploiting large-volume sample stacking using an electroosmotic flow pump, the sensitivity of the proposed capillary electrophoresis system coupled with UV detection was significantly improved with limits of detection of 3, 5, 1 mg/L for chondroitin sulfate, dermatan sulfate, and hyaluronic acid, respectively. The developed method was applied to the determination of chondroitin sulfate and hyaluronic acid in cell culture media, cerebrospinal fluid, cosmetic products, and supplementary samples with highly acceptable accuracy and precision. Therefore, the proposed capillary electrophoresis approach was found to be simple, rapid, and reliable for the determination of chondroitin sulfate, dermatan sulfate, and hyaluronic acid in cell culture media, cerebrospinal fluid, cosmetic, and supplementary samples without sample pretreatment.

Abstract
Complex natural polysaccharides, glycosaminoglycans (GAGs), are a class of ubiquitous macromolecules that exhibit a wide range of biological functions and participate and regulate multiple cellular events and (patho)physiological processes. They are generally present either as free chains (hyaluronic acid and bacterial acidic polysaccharides) or as side chains of proteoglycans (PGs; chondroitin/dermatan sulfate, heparin/heparan sulfate, and keratan sulfate) and are most often found in cell membranes and in the extracellular matrix. The recent emergence of modern analytical tools for their study has produced a virtual explosion in the field of glycomics. CE, due to its high resolving power and sensitivity, has been useful in the analysis of intact GAGs and GAG-derived oligosaccharides and disaccharides affording concentration and structural characterization data essential for understanding the biological functions of GAGs. In this review, novel off-line and on-line CE-MS and MS/MS methods for screening of GAG-derived oligosaccharides and disaccharides will be discussed.

Abstract
CE conditions for monitoring the unsaturated disaccharides of hyaluronic acid (di-HA) and chondroitin sulfate (di-CS) using an alkaline tetraborate buffer, electrokinetic sample injection, and UV absorption detection at 232 nm are reported. Separations were performed in an uncoated fused-silica capillary having reversed polarity and reversed electroosmosis generated with the addition of CTAB to the buffer. The influence of various separation parameters, including the concentration of CTAB, buffer pH, concentration of tetraborate, and applied voltage, on the resolution of the two disaccharides was investigated. Baseline separation was obtained with 25 mM tetraborate at pH 10.0 and having 0.05 mM CTAB. Chloride and phosphate in the sample are beneficial for the stacking of the disaccharides, with di-HA forming a much sharper peak than di-CS. Using samples prepared in 25 mM Tris-HCl (pH 7.5) and electrokinetic injection at the cathode at -10 kV for 40 s, linear relationships between the corrected peak area and the concentration of the disaccharides have been found in the ranges of 1.0-400.0 and 0.1-1.0 microg/mL (0.2-1.0 microg/mL for di-CS), with correlation coefficients being >0.9933 in all cases. The RSDs of detection times and corrected peak areas were between 1.13-1.24 and 1.57-2.13%, respectively. Applied to human serum samples that were prepared by ethanol precipitation and depolymerization of the two polysaccharides with chondroitinase ABC reveals comigration of endogenous compounds with di-HA and a sample-dependent detection time. The di-HA content in the serum sample can be estimated via subtraction of the blank peak that is obtained without enzymatic hydrolysis.

Abstract
Meningococcal polysaccharides are medically important molecules and are the active components of vaccines against Neisseria meningiditis serogroups A, C, W135, and Y. This study demonstrates that free solution capillary zone electrophoresis (CZE) using simple phosphate/borate separation buffers is capable of separating intact, native polysaccharides from these four serogroups. Separation appeared to be robust with respect to variations in test conditions and behaved in expected ways with respect to changes in temperature, ionic strength, and addition of an organic modifier. Serogroups W135 and Y are composed of sialic acid residues alternating with either galactose or glucose, respectively. Separation of these serogroups could be achieved using phosphate buffer and was therefore not dependent on differential complexation with borate. Addition of sodium dodecyl sulfate to the separation buffer (i.e., MEKC) resulted in peak splitting for all four serogroups. Changes in polysaccharide size did not affect migration time for the size range examined, but serogroup C polysaccharide (a sialic acid homopolymer) was separable from sialic acid monosaccharide. CZE quantification of multiple lots of each of the four serogroups was compared to wet chemical determination by phosphorus or sialic acid measurement. Results from CZE determination showed good agreement with the wet chemical methods.

Abstract
A multi-layer membrane system was used to measure in vitro release of hydrophilic macromolecules such as hyaluronic acid (HA) from semisolid formulations. One enzymatically digested HA-derivative with molecular mass of 22 kDa (HA-D) and 1200 kDa intact HA (HA) were incorporated into three semisolid formulations: water-containing hydrophilic ointment (WHO), amphiphilic cream (AC) and water-containing wool wax alcohol ointment (WWO). Because of the high hydrophilic properties of HA-D and HA, the artificial model membranes consisted of collodion as the matrix and glycerol as the hydrophilic acceptor phase. The area under the concentration-time curve and the mean dissolution time were used as a quantitative parameter to characterise the rate and extent of release in vitro. This study showed that the HA-D and HA release as hydrophilic substances from WHO was higher than both from AC and WWO. It was observed that 83% of HA-D1 was released from WHO after 2 h; in contrast, only 10% was released from 2% HA from the same vehicle during the same time. In conclusion, the in vitro availability of enzymatically digested HA-D was higher for WHO than for the other formulations, AC and WWO. Similarly, the availability of HA-D was higher than that of HA from the same formulations.

Abstract
Three different hyaluronic acid fragment preparations (HAF) derived from hyaluronic acid (HA) by hyaluronate lyase digestion have been investigated. The amount of these fragment mixtures in pharmaceutical formulations was determined by liquid chromatography-electrospray tandem mass spectrometry (LC/MS/MS). HAF analysis was performed in less than 8 min using a Nucleosil 100-7 C2 column. Based on the assumption that the mass distribution is kept constant, which is confirmed by the calibration results, quantification can be carried out relating to the most intense fragments. For that purpose, the ratios of the peak areas of product ions of m/z=378 (tetramer, hexamer, octamer) to the peak area of m/z=83 ([2xmaltose-H(+)], internal standard) were calculated. Calibration was done for each HAF and good linearity from 5 to 80 microg/ml has been shown. To evaluate the molecular weight distribution of the fragment preparations used in this approach MALDI-TOF, mass spectra have been collected.

Abstract
A new method for the identification of oligosaccharides obtained by enzymatic digestion of hyaluronic acid (HA) with bacterial hyaluronidase (HA lyase, E.C. 4.2.2.1, from Streptococcus agalactiae) using online capillary electrophoresis/electrospray mass spectrometry (CE/ESI-MS) is presented. A fused-silica capillary coated with polyacrylamide was used with a 40 mM ammonium acetate buffer at pH 9.0 and a separation voltage of +30 kV applied to the inlet. Separation was achieved for oligosaccharides containing 4-16 monomers. The migration behavior follows the chain length of the oligomers, regardless of charge state. However, no linear relationship was found for the relation between mobility and chain length. Using an ion trap mass analyzer, complementary structural information was obtained by MS/MS and MS(n) experiments.
