This study represents a pioneering investigation into using microfluidic technology for manufacturing PLA and PLGA nanocarriers (NCs) loaded with tracer molecules or metals through co-precipitation protocol that involves saturating the water phase. The effects of total flow rate (TFR), ratio (FRR), surfactant amount, polymer concentration on particle sizes distributions were examined. average size PLA-NCs varied from 349 ± 175 nm to 170 64 nm, surface charges ranging -13 -6 mV. In contrast, PLGA-NCs had an between 192 46 100 34 -23 mV -53 Increasing TFR 6 10 mL/min fixed FRR 1:1 reducing concentrations in organic phase 20 5 mg/mL generally resulted smaller NC (monodispersed), consistently exhibiting dimensions. Under these specific conditions, Rhodamine B (Rhod) gold (Au) successfully loaded, achieving encapsulation efficiencies exceeding 50 %.

Naturally occurring extracellular vesicles (EVs) and synthetic nanoparticles like liposomes have revolutionized precision diagnostics medicine. EVs excel in biocompatibility cell targeting, while offer enhanced drug loading capacity scalability. The clinical translation of is hindered by challenges including low yield heterogeneity, whereas face rapid immune clearance limited targeting efficiency. To bridge these gaps, biomimetic (SVs) emerged as innovative platforms, combining the advantageous properties liposomes. This review emphasizes critical aspects EV biology, such mechanisms EV-cell interaction source-dependent functionalities modulation, tissue regeneration, informing SV engineering. We reviewed a broad array SVs, with focus on lipid bilayered functionalized proteins. These include cell-derived nanovesicles, protein-functionalized liposomes, hybrid vesicles. By addressing current highlighting opportunities, this aims to advance SVs for transformative biomedical applications.

The FDA’s approval of Danicopan (Vodeya) on 1 April 2024, represents a significant advancement in the treatment Paroxysmal Nocturnal Hemoglobinuria (PNH). As first oral serine protease factor D inhibitor, complements existing C5 inhibitors by addressing both intravascular and extravascular hemolysis. In phase 3 ALPHA trial, as an add-on therapy to ravulizumab or eculizumab significantly improved hemoglobin levels, with least squares mean difference 2.44 g/dL compared placebo ( P < 0.0001). Key advancements include its ability reduce transfusion dependency, improve patient quality life, convenient administration intravenous therapies. Potential side effects severe headache, fever, blurred tunnel vision, sudden dizziness, increased risk infections encapsulated organisms, along rare adverse events such elevated liver enzymes neutropenia. Danicopan’s fills critical therapeutic gap, offering transformative approach managing PNH.
