Capillary Electrophoresis: Applications

481
Capillary electrophoretic separations offer various modes, each with unique applications. These modes include capillary zone electrophoresis, capillary gel electrophoresis, capillary array electrophoresis, capillary isoelectric focusing, capillary isotachophoresis, micellar electrokinetic chromatography, and capillary electrochromatography.
Capillary zone electrophoresis (CZE) separates ionic components based on their electrophoretic mobility. It has been used to separate proteins, amino acids,...

Blood Studies I: ABG and VBG

638
Blood studies are critical in the medical field, enabling healthcare professionals to assess a patient's health status accurately. This page will focus on two significant blood studies: Arterial Blood Gas (ABG) and Venous Blood Gas (VBG).
Arterial Blood Gas (ABG)
Arterial Blood Gas (ABG) studies are crucial for assessing the lungs' ability to supply oxygen and remove carbon dioxide, reflecting the patient's ventilation status. They also help understand the kidneys' capacity to...

Area of Science:

  • Biomedical Engineering
  • Clinical Diagnostics
  • Point-of-Care Testing

Background:

  • Whole blood analysis is crucial for disease diagnosis and monitoring.
  • The COVID-19 pandemic underscored the need for robust screening capabilities.
  • Minimally invasive capillary blood sampling reduces pain and tissue damage compared to venepuncture, enhancing point-of-care testing.

Purpose of the Study:

  • To provide an overview of state-of-the-art capillary blood sampling techniques.
  • To review established and novel methods for capillary blood release.
  • To compare different capillary blood sampling methods and methods for enhancing collection.

Main Methods:

  • Review of established and novel techniques for releasing blood from skin capillaries.
  • Comparative analysis of capillary blood sampling methods (mechanism, site, size, cost, wound healing, pain perception).
  • Overview of methods for enhancing capillary blood collection.

Main Results:

  • Microneedles are identified as a potentially preferred method for pediatric blood collection due to painlessness.
  • Jet injection is highlighted as a versatile method for both blood collection and drug delivery.
  • Comparison of methods based on key performance indicators such as pain, wound geometry, and healing.

Conclusions:

  • Microneedle technology holds significant potential to improve pediatric blood collection experiences and outcomes.
  • Jet injection offers a dual-purpose application for diagnostics and therapeutics.
