Their unique properties, stemming from the self-assembly of peptides, enable them to overcome limitations associated with traditional delivery methods, paving the way for more effective therapeutic interventions and advanced biomaterials.

At the core of this advancement lies liquid-liquid phase separation (LLPS), a fundamental biological process wherein molecules spontaneously demix into distinct liquid phases. Peptides, with their tunable sequences and inherent self-assembly capabilities, are proving to be exceptional building blocks for engineering these liquid droplets. This process, often referred to as coacervation, allows for the creation of concentrated condensates that can encapsulate and protect a variety of payloads, ranging from small molecules to larger biomacromolecules like proteins and nucleic acids.Redox-responsive peptide-based complex coacervates as ...

Recent research has highlighted significant progress in the design of liquid-like microdroplets based purely on peptide sequences. Unlike conventional delivery systems such as lipid nanoparticles or polymer-based carriers, peptide-based liquid droplets offer inherent biocompatibility and biodegradability. Their dynamic nature, a characteristic of condensates that are dynamic liquid droplets, allows for responsive behavior, such as controlled release of cargo triggered by specific environmental cues like pH or redox potential. For instance, studies on redox-responsive peptide-based complex coacervates demonstrate their ability to form and dissolve reversibly under redox flux, making them ideal celldelivery vehicles.

The versatility of these peptide-based biomimetic condensates extends to their ability to mimic the behavior of membraneless organelles found within cells. This biomimicry further enhances their potential for intracellular delivery. Indeed, coacervate droplets have emerged as intracellular delivery vehicles, with ongoing research focusing on elucidating their precise internalization mechanisms. This capability is particularly crucial for delivering therapeutics directly into cells, thereby enhancing efficacy and minimizing off-target effects.
