The review used a variety of sources from 2020 to 2025, including preprint sites (bioRxiv, medRxiv), grey literature/press-release outlets including EurekAlert! and ScienceDaily, PubMed, Embase, Scopus, Web of Science, BIOSIS, and Google Scholar. While hemocyanin's unique properties allow for adaptation to diverse environments, its direct application as an artificial human blood substitute faces significant biological and immunological hurdles. The report then transitions to a comprehensive overview of recent advancements in artificial human blood transfusion, focusing on hemoglobin-based oxygen carriers (HBOCs), perfluorocarbon-based oxygen carriers (PFCs), and stem cell-derived red blood cells.

Donepezil, a widely prescribed drug for Alzheimer's, suffers from poor oral bioavailability, delayed onset, and limited nootropic activity due to extensive systemic metabolism. To address these limitations, this study aimed to develop and optimize a Donepezil-loaded lipid-based nanoemulsion for enhanced nose-to-brain delivery. A Box-Behnken Design (BBD) was employed to optimize three formulation variables: drug-to-lipid ratio (1:2 to 1:6), surfactant concentration (1-2% w/v), and stirring speed (1500-2500 rpm), with their effects assessed on particle size, drug entrapment efficiency, and drug loading. Based on solubility and hydrophilic-lipophilic balance, Glyceryl Monostearate and Tween 80 were selected as excipients. Seventeen formulations were prepared and analyzed using Response Surface Methodology. The optimized formulation (Batch 18) exhibited a particle size of 160.12 nm, entrapment efficiency of 80.75%, and drug loading of 19.98%, with a desirability score of 0.977.

The optimized nanoemulsion showed enhanced brain-targeting efficiency and improved nootropic potential of Donepezil via the intranasal route, presenting a promising strategy for Alzheimer's therapy.
