Peptide-based liquid droplets are rapidly emerging as a significant innovation in the field of delivery vehiclesLiquid Droplets as Emerging Biomaterials - PMC. These dynamic structures, often formed through liquid-liquid phase separation (LLPS), offer novel opportunities for encapsulating and transporting a variety of payloads, from therapeutic agents to biomolecules. Unlike traditional delivery systems such as lipid nanoparticles or polymer-based carriers, peptide-based liquid droplets leverage the inherent properties of peptides to create sophisticated, often biomimetic, constructs.作者：B Wu·2023·被引用次数：6—(2023).Peptide-based liquid droplets as emerging delivery vehicles.

The recent progress in designing these liquid-like microdroplets, also known as coacervates, highlights their potential to revolutionize drug delivery and other biomedical applications.
The fundamental principle behind these emerging delivery vehicles lies in the self-assembly of peptidesRational Design of Purely Peptidic Amphiphiles for Drug .... Peptides, being short chains of amino acids, can be engineered to exhibit specific interactions, leading to the spontaneous formation of ordered structures. When these peptides undergo liquid-liquid phase separation, they coalesce into distinct liquid dropletsThis Comment highlightsrecent progress in the design of liquid-like microdroplets, or coacervates, based on peptides and produced through liquid–liquid phase .... This process is analogous to the formation of membraneless organelles within cells, suggesting a natural and potentially biocompatible mechanism for encapsulation. The ability of these peptide-based condensates to form dynamic liquid droplets makes them uniquely suited for carrying sensitive cargo.
The appeal of peptide-based liquid droplets as delivery vehicles stems from several key advantages. Firstly, their peptide nature allows for inherent biocompatibility and biodegradability, reducing the risk of immune responses and off-target toxicity often associated with synthetic materialsPeptides for Liquid‐Liquid Phase Separation: An Emerging .... Secondly, the modularity of peptide design means that their properties, such as charge, hydrophobicity, and responsiveness to environmental cues (like pH or redox potential), can be precisely tuned. This programmability enables the creation of smart delivery systems that can release their cargo under specific conditions.
These characteristics open up a broad spectrum of applications.作者：L Lu·2026—Langer,Peptide-based liquid droplets as emerging delivery vehicles, Nat. Rev. Mater., 2023, 8, 139–141 Search PubMed. J. Wang, L. Hu, H ... Peptide-based coacervate droplets are being explored as advanced carriers for nucleic acids, proteins, and small molecule drugs. Their ability to form liquid-like interiors can protect fragile biomolecules from degradation and facilitate their entry into cells. Furthermore, their potential extends to intracellular delivery, where they can mimic natural cellular processes to transport molecules within the cell.In thisnewresearch, Ankit and Salma designed a multi-component biomolecular condensate capable of stabilizing and confining amyloids in itsliquidinterior. The development of redox-responsive peptide-based complex coacervates, for instance, allows for controlled release triggered by the intracellular redox environment.

Researchers are actively investigating various strategies for designing peptide sequences that promote LLPS作者：J Liu·2023·被引用次数：106—Peptide-based microdroplets create new opportunities for deliverycompared with other types of delivery vehicle, such as lipid and polymer .... This involves understanding the interplay of electrostatic interactions, hydrophobic effects, and pi-pi stacking between peptide moleculesEmerging Technologies in the Delivery of Proteins and .... For example, peptides with alternating charged residues or those containing specific aromatic amino acids are often employed to drive coacervation.
The resulting droplets can range in size from nanometers to micrometers, and their stability can be further enhanced through cross-linking mechanisms, such as disulfide bondsMaking peptides - Spiral. This allows for the creation of more robust delivery systems capable of withstanding physiological conditions. The design of purely peptidic amphiphiles, for example, has paved the way for creating self-assembling structures that can encapsulate drugs, offering an alternative to traditional drug delivery mechanisms.
While peptide-based liquid droplets represent a promising new class of delivery vehicles, several challenges remain. Optimizing the efficiency and specificity of payload encapsulation and release is crucial for therapeutic applications. Understanding the precise mechanisms of cellular uptake and intracellular trafficking of these droplets is also an ongoing area of research. Furthermore, scaling up the production of well-defined peptide sequences for coacervate formation and ensuring their long-term stability and safety in vivo will be critical for their translation into clinical practiceRedox-responsive peptide-based complex coacervates as ....
