“…CE-capacitively coupled contactless conductivity detection (CE-C 4 D) uses differences in charge, size, and shape of the analyte along with the mobility of the BGE co-ion while adjusting the concentration of the BGE and inner diameter of the capillary to achieve better separation and detection [174]. Through CE-C 4 D, AAs, sugars, and many other low UV-absorbing substances may be directly analyzed under their native condition without requiring lengthy derivatization [175,176]. The technique is characterized by low injection volumes, a short migration time, and moderate to high sensitivity.…”

The significance of branched‐chain amino acids in diseases was clearly shown over the years. This review aims to describe the available techniques for their analytical determination. The article provides examples of the use of various analytical methods. The methods are divided into two categories: derivatization and non‐derivatization approaches. Separation is achieved through different chromatography or capillary electrophoresis techniques and can be combined with different detectors such as flame ionization, ultraviolet, fluorescence, and mass spectrometry. It compares the application of various derivatization reagents or detection as such for different detectors.

“…An alternative MD approach is to combine CE with capacitively coupled contactless conductivity detection (C4D) ( 54 – 56 ). C4D is a universal detection technique that is particularly sensitive for low-molecular-weight substances that dissociate into ions, such as minerals, amino acids, carbohydrates, amines, organic acids, as well as many pharmaceuticals including ATBs ( 57 , 58 ). Using CE-C4D, metabolites and drugs are determined in their native forms commonly found in living tissues, without the need for the complicated derivatisation associated with CE-LIF ( 59 ).…”

Diabetic foot is a serious late complication frequently caused by infection and ischaemia. Both require prompt and aggressive treatment to avoid lower limb amputation. The effectiveness of peripheral arterial disease therapy can be easily verified using triplex ultrasound, ankle-brachial/toe-brachial index examination, or transcutaneous oxygen pressure. However, the success of infection treatment is difficult to establish in patients with diabetic foot. Intravenous systemic antibiotics are recommended for the treatment of infectious complications in patients with moderate or serious stages of infection. Antibiotic therapy should be initiated promptly and aggressively to achieve sufficient serum and peripheral antibiotic concentrations. Antibiotic serum levels are easily evaluated by pharmacokinetic assessment. However, antibiotic concentrations in peripheral tissues, especially in diabetic foot, are not routinely detectable. This review describes microdialysis techniques that have shown promise in determining antibiotic levels in the surroundings of diabetic foot lesions.

“…In fact, this analytical technique can nowadays be considered a powerful tool in this topic as it has been highlighted by our previous review papers published in Electrophoresis since 2006 [1][2][3][4][5][6][7][8]. The high potential of CE in this field has given rise to a considerable number of review articles as it is demonstrated by Table 1, which summarizes the main reviews published within the period covered by the present work on the application of CE methods in food analysis and Foodomics [9][10][11][12][13][14][15][16][17][18][19][20][21]. Along with a comprehensive book collection that provides an interesting assembly of articles devoted to facing challenges related to food quality, safety, and interactions food-health from a Foodomics perspective [9], other review works devoted to the application of CE for food analysis [18] or their specific coupling to mass spectrometry (MS) for metabolomics [13,14] or food analysis [10] have also been published.…”

“…The most recent applications of CE to the analysis of amino acids (AAs) [12], peptides and proteins [22], acrylamide [19], or dairy products [21] as well as its use in chiral analysis [16] or for the proteomics characterization of food-derived bioactive peptides [15] have also been recently reviewed. Moreover, different reviews focused on the potential of microchip electrophoresis for the analysis of foodstuffs and beverages [11], pathogenic bacteria and viruses [17], or peptides [20] have been published.…”

This work presents a revision of the main applications of capillary electromigration (CE) methods in food analysis and Foodomics. Papers that were published during the period March 2021 to March 2023 are included. The work shows the multiple CE methods that have been developed and applied to analyze different types of molecules in foods and beverages. Namely, CE methods have been applied to analyze amino acids, biogenic amines, heterocyclic amines, peptides, proteins, phenols, polyphenols, pigments, lipids, carbohydrates, vitamins, DNAs, contaminants, toxins, pesticides, additives, residues, small organic and inorganic compounds, and other minor compounds. In addition, new CE procedures to perform chiral separation and for evaluating the effects of food processing as well as the last developments of microchip CE and new applications in Foodomics will be also discussed. The new procedures of CE to investigate food quality and safety, nutritional value, storage, and bioactivity are also included in the present review work.
