At their core, peptide micelles exploit the amphiphilic nature of peptides. These molecules, composed of both hydrophilic (water-loving) and hydrophobic (water-repelling) regions, spontaneously arrange themselves in aqueous environments to minimize unfavorable interactions.Multifunctional peptide-assembled micelles for simultaneously ... This self-assembly process typically leads to the formation of a core-shell structure, where the hydrophobic segments aggregate to form an inner core, shielded from water by the hydrophilic segments that form an outer shell. This fundamental characteristic allows peptide micelles to encapsulate and deliver a wide range of molecules, including hydrophobic drugs that are otherwise difficult to administer作者:K Esparza·2019·被引用次数:22—Sterically stabilizedmicelle(SSM) is a self-assembled nanoparticle ideal for the delivery of therapeuticpeptides..

One of the key advantages of peptide micelles lies in their biomocompatibility and tunability. Unlike synthetic polymer-based nanoparticles, peptides are natural building blocks of biological systems, leading to reduced immunogenicity and improved biodegradability. Furthermore, the precise control over amino acid sequences allows for the fine-tuning of micelle properties, such as size, stability, and surface chemistry. This modularity is crucial for developing targeted drug delivery systems. For instance, researchers have engineered Arg-Gly-Asp (RGD) peptide-decorated nanomicelles for enhanced tumor targeting, leveraging the RGD sequence's affinity for integrins present on cancer cells. Similarly, peptide-functionalized PEG-PLA micelles are being developed to specifically target tumor tissues, allowing for higher drug concentrations at the site of disease and reduced systemic toxicity.
