Introduction

Microdialysis, a powerful technique in biomedical research, offers a window into the intricate world of cellular and molecular processes within living organisms. By sampling extracellular fluid in real-time, microdialysis allows researchers to monitor changes in biochemical parameters, assess drug distribution, and physiological responses [1].

At its core, microdialysis involves the insertion of a small probe, typically made of semipermeable membrane, into the tissue of interest. This probe is perfused with a sterile solution known as perfuse, which flows through the membrane via diffusion. As perfuse circulates through the tissue, it exchanges molecules with the surrounding extracellular fluid, allowing for the continuous sampling of analytes such as neurotransmitters, metabolites, cytokines, and drugs [2, 3].

In neuroscience research, microdialysis is used to monitor neurotransmitter levels in specific brain regions, elucidating the mechanisms underlying neurological disorders such as Parkinson's disease, Alzheimer's disease, and epilepsy. Microdialysis is a valuable tool for pharmacokinetic studies, allowing researchers to assess drug distribution, metabolism, and pharmacodynamics in vivo. This information is critical for optimizing drug dosing regimens and evaluating drug efficacy and safety[4].

Microdialysis can be used to measure changes in metabolic parameters, such as glucose, lactate, and oxygen, in response to physiological stimuli or pathological conditions. This enables researchers to investigate tissue metabolism, energy utilization, and cellular responses in real-time. Microdialysis studies can assess the impact of toxins, pollutants, and environmental stressors on tissue homeostasis and cellular function. By monitoring changes in biomarkers and metabolites, researchers can identify early signs of toxicity and evaluate the effectiveness of interventions[5, 6].

The placement of the microdialysis probe is crucial for accurate sampling of the target tissue or region of interest. Proper positioning ensures optimal diffusion of perfuse and reliable measurement of analytes. The composition of perfuse, including the choice of buffer, pH, and flow rate, can influence the recovery and detection of analytes. Optimization of perfuse parameters is essential for obtaining reliable data[7].

Analyzing the collected samples requires sensitive and specific analytical techniques, such as chromatography, mass spectrometry, or Enzyme-Linked Immuno-Sorbent Assays (ELISA), depending on the analytes of interest. While microdialysis offers unique insights into dynamic physiological processes, it also presents challenges and limitations, including technical constraints, probe biocompatibility, and data interpretation. Future advancements in microdialysis technology, such as the development of miniaturized probes, improved analytical methods, and real-time monitoring systems, hold promise for overcoming these challenges and expanding the applications of microdialysis in biomedical research[8, 9].

Microdialysis studies represent a valuable approach for investigating complex biological systems in vivo, offering real-time monitoring of biochemical parameters and dynamic physiological processes. By providing insights into neurotransmission, metabolism, drug distribution, and tissue responses, microdialysis contributes to our understanding of health and disease and informs the development of novel therapies and interventions. With continued innovation and interdisciplinary collaboration, microdialysis is poised to remain at the forefront of biomedical research, driving advancements in basic science, clinical medicine, and therapeutic discovery[10].
