Peptide hydrogels are three-dimensional network structures formed by the crosslinking or self-assembly of peptide molecules, with high hydration and good biocompatibility. They often exhibit a high degree of controllability, including the ability to adjust hydrogel mechanical strength, degradability, and bioactivity by modifying the peptide sequence, crosslinking density, or other physicochemical parameters. These hydrogels have excellent drug carrier properties, enabling efficient drug delivery to target areas via controlled release mechanisms, and have wide applications in biomedical, drug delivery, tissue engineering, and other fields.
BOC Sciences has rich experience and a deep technical foundation in peptide design, synthesis, and modification. The performance of peptide hydrogels largely depends on the selected peptide sequence and structure. Therefore, the precise design of suitable peptides is the first step in preparing efficient and multifunctional hydrogels. With its advanced technical platform and strong R&D capabilities, BOC Sciences can provide comprehensive services, from peptide sequence design to final synthesis and modification, ensuring customized solutions for customers.
BOC Sciences designs peptide sequences suitable for hydrogel systems through in-depth analysis of the characteristics of target molecules, cells, or tissues, ensuring ideal biocompatibility, structural stability, and functional activity.
BOC Sciences uses advanced peptide synthesis methods such as Solid Phase Peptide Synthesis (SPPS) and Liquid Phase Peptide Synthesis (LPPS) to rapidly and accurately synthesize peptides of varying lengths and complexities.
According to customer needs, BOC Sciences can modify peptides in various ways, including phosphorylation, acetylation, PEGylation, crosslinking, etc., to improve their stability, solubility, and bioactivity in hydrogels.
BOC Sciences can also introduce drug-binding sites into the peptide structure to regulate its affinity, stability, and controlled release properties to optimize the drug delivery performance of hydrogels.
To meet the needs of different application scenarios, BOC Sciences employs various advanced techniques to prepare peptide-based hydrogels. These methods not only enable hydrogel preparation under mild conditions but also allow the structure, properties, and functions of the hydrogels to be adjusted according to specific project requirements. Through precise design and control, BOC Sciences can offer highly customized peptide hydrogel solutions to meet the needs in drug delivery, tissue engineering, regenerative medicine, and other fields.
The self-assembly method forms stable three-dimensional network structures through interactions between peptide molecules (such as hydrogen bonds, electrostatic interactions, van der Waals forces, etc.). The advantage of this method lies in its ability to operate under mild conditions and spontaneously form hydrogels with predefined functions. With advanced self-assembly technology, BOC Sciences can precisely control the structure and morphology during the self-assembly process to obtain hydrogels with different sizes and functions.
The crosslinking method uses chemical crosslinking agents to connect peptide molecules, forming a stable three-dimensional network structure. This method can control the physicochemical properties of hydrogels through different crosslinking chemical reactions (such as esterification, amination, etc.). BOC Sciences has deep experience in the crosslinking method and can customize crosslinking conditions according to customer needs to achieve the best-performing peptide hydrogels.
The copolymerization method involves copolymerizing different types of monomers (including peptides and other synthetic monomers) into composite hydrogels. This method combines the biological activity of peptides with the functionality of other monomers, thus developing hydrogels with various properties. BOC Sciences provides customized copolymerization services, capable of designing and synthesizing multifunctional hydrogels according to customer needs.
Temperature-responsive hydrogels are materials that change their hydration or structure in response to temperature. BOC Sciences develops hydrogels that can respond to external temperature changes by adjusting the hydrophilic and hydrophobic regions in the peptide sequence. These hydrogels exhibit significant morphological changes under physiological temperature fluctuations, with wide applications in drug delivery and tissue engineering.
To ensure the performance of peptide hydrogels in practical applications, BOC Sciences provides comprehensive performance testing and drug delivery function optimization services. These tests and optimization measures not only help customers assess the physicochemical properties of the hydrogels but also further enhance their effectiveness in biomedical applications such as drug delivery. Below are BOC Sciences' specific services in performance testing and drug delivery function optimization:
Peptide hydrogels' drug loading capacity is tested using High-Performance Liquid Chromatography (HPLC) and UV-Visible Spectrophotometry (UV-Vis), while in vitro release experiments optimize the sustained-release characteristics of the drug.
The degradation rate of peptide hydrogels in physiological environments is evaluated, along with long-term stability testing to ensure that no physical or chemical changes affect the gel's performance during storage.
Peptide hydrogels' mechanical strength, elasticity, and toughness are tested using Dynamic Mechanical Analysis (DMA) and other methods to ensure they can withstand external forces and maintain structural stability in applications.

A peptide hydrogel is a hydrogel material formed by the crosslinking or self-assembly of peptide molecules into a three-dimensional network structure. Due to the excellent biocompatibility and adjustability of peptides, they can form gel-like structures in aqueous environments, making them widely used in drug delivery, tissue engineering, and biosensors, among other fields. Peptide hydrogels not only mimic the extracellular matrix but also provide a stable biophysical environment through molecular interactions, supporting cell growth, differentiation, and regeneration. Their adjustable mechanical properties and biodegradability make them ideal biomaterials.
The preparation of peptide hydrogels typically involves the design, synthesis, and crosslinking process. First, a suitable peptide sequence is designed to enable self-assembly or crosslinking capabilities. The peptide is then synthesized through solid-phase peptide synthesis (SPPS) or liquid-phase peptide synthesis (LPPS) methods. Next, the peptide is dissolved in an appropriate solvent, and the hydrogel is induced by changes in temperature, pH, or the addition of crosslinkers. Common crosslinking methods include chemical crosslinking, self-assembly, and copolymerization. During this process, adjusting the synthesis conditions can achieve the desired properties of the hydrogel, such as mechanical strength, degradation rate, and biocompatibility.
