Plasma-derived extracellular vesicles (EVs) are promising sources of biomarkers. It is still a challenge to isolate EVs from small amount human plasma for downstream proteomic analysis. The isolation process hindered by contamination with high-abundance blood proteins and lipoprotein particles, which adversely impact analyses. Moreover, although EV immune-isolation via magnetic beads often integrates flow sorting Western blotting (WB), it lacks compatibility nanoparticle tracking analysis (NTA) To address these issues, we have developed functional affinity bead, EVlent (Extracellular Vesicles isoLated Efficiently, Naturally, Totally), enabling the rapid efficient plasma. By optimizing quantities used, characterized isolated through WB, NTA, transmission electron microscopy (TEM), showing successful Proteomic identified over 2000 15,000 peptides 100 μL nearly 1000 trace samples as 5 μL. Additionally, this method significantly reduced contaminants, including lipoproteins, compared ultracentrifugation. Finally, applied strategy healthy individuals those Parkinson's disease, identifying four potential biomarkers that provide guidance clinical diagnosis.

Extracellular particles (EPs), including extracellular vesicles (EVs) and non-vesicular (NVEPs), are multimolecular biomaterials released by cells that play a crucial role in intercellular communication. Recently, new subtypes of EPs associated with central nervous system (CNS), such as exophers supermeres have been identified. These provide perspectives for understanding the pathological progression CNS disorders confer potential diagnostic value liquid biopsies neurodegenerative diseases (NDs). Moreover, emerged promising drug delivery vehicles targeted platforms CNS-specific therapies. In this review, we delineate landscape EP their roles pathophysiology diseases. We also review recent advances EP-based diagnosis NDs highlight importance analytical single-particle resolution exploitation biomarkers.

Although microparticles are frequently used in chemistry and biology, their effectiveness largely depends on the homogeneity of particle size distribution. Microfluidic devices to separate purify particles based have been developed, but many require expensive cleanroom manufacturing processes. A cost-effective, passive microfluidic separator is presented, capable efficiently sorting purifying spanning range 15 µm 40 µm. Fabricated from Polymethyl Methacrylate (PMMA) substrates using laser ablation, this device circumvents need for facilities. Prior fabrication, rigorous optimization device's design was carried out through computational simulations conducted COMSOL Multiphysics. To gauge its performance, chitosan were employed as a test case. The results notably promising, achieving precision 96.14 %. This quantitative metric underscores size-based separation. low-cost accessible offers pragmatic solution laboratories researchers seeking precise control over sizes, without constraints environments. innovation not only mitigates limitations tied traditional cleanroom-based fabrication also widens horizons various applications within realms biology.

Extracellular vesicles (EVs) are lipid bound particles derived from their original cells, which play critical roles in intercellular communication through cargoes, including protein, lipids, and nucleic acids. According to biogenesis release pathway, EVs can be divided into three categories: apoptotic (ApoVs), microvesicles (MVs), small (sEVs). Recently, the role of oral disease has received close attention. In this review, main characteristics described, classification, biogenesis, biomarkers, components. Moreover, therapeutic mechanism tissue regeneration is discussed. We further summarize current status pulp/periodontal discuss potential mechanisms. The pulp periodontal might involve promotion immunomodulatory capabilities. Furthermore, we highlight challenges translational use EVs. This review would provide valuable insights strategies dental regeneration.

This review aims to address the significant challenges of treating central nervous system (CNS) disorders such as neurodegenerative diseases, strokes, spinal cord injuries, and brain tumors. These are difficult manage due complexity disease mechanisms protective blood–brain barrier (BBB), which restricts drug delivery. Recent advancements in nanoparticle (NP) technologies offer promising solutions, with potential applications delivery, neuroprotection, neuroregeneration. By examining current research, we explore how NPs can cross BBB, deliver medications directly targeted CNS regions, enhance both diagnostics treatment. Key NP strategies, passive targeting, receptor-mediated transport, stimuli-responsive systems, demonstrate encouraging results. Studies show that may improve minimize side effects, increase therapeutic effectiveness models Alzheimer’s, Parkinson’s, stroke, glioblastoma. thus represent a approach for disorder management, combining delivery diagnostic capabilities enable more precise effective treatments could significantly benefit patient outcomes.
