What is a Hyaluronic Acid Microsphere?
Hyaluronic acid microspheres consist of hyaluronic acid (HA) polymer particles, which serve various medical purposes in drug delivery systems, as well as tissue repair and cosmetic surgery applications. These microspheres demonstrate superior biocompatibility and hydration ability, which enables effective protection, targeted drug release, and bioactive molecule delivery for precise medical treatment. HA Microspheres can be customized in size and surface properties to match specific application needs, which enables various functional modification possibilities. HA naturally breaks down in the body, which enables these microspheres to degrade without leading to persistent adverse effects. In tissue engineering applications, HA Microspheres serve as a tool to encourage cellular growth and repair, while showing significant promise for skin regeneration and joint repair.

Pure HA Microspheres
Pure HA Microspheres are the most common type, composed solely of HA. These microspheres retain the natural biocompatibility of HA, making them suitable for biomedical applications such as tissue engineering, drug delivery, and injectable drug carriers.
Crosslinked HA Microspheres
Crosslinked HA Microspheres are formed by chemically crosslinking HA molecules, creating a more stable and structurally robust three-dimensional network. This type of microsphere enhances drug-loading capacity, prolongs drug release time, and improves mechanical strength.
Functionalized HA Microspheres
Functionalized HA Microspheres incorporate various functional groups (e.g., carboxyl, amino, polyvinyl alcohol) through surface modification or chemical crosslinking. These microspheres exhibit enhanced targeting and biocompatibility in specific environments and are widely used in targeted drug delivery, molecular recognition, cell capture, and disease detection.
HA-Polymer Composite Microspheres
In addition to pure HA Microspheres, we also provide microspheres composed of HA and other biomaterials (such as polyvinyl alcohol, polylactic acid, and chitosan). These composite microspheres combine the advantages of HA and other materials, improving drug-loading capacity, stability, and biocompatibility.
HA-Lipid Composite Microspheres
HA-lipid composite microspheres are formed by combining HA with lipid materials. These microspheres offer excellent lipophilic drug-loading capabilities and superior biodegradability. Lipid composite microspheres are effectively used for delivering lipophilic drugs, antibodies, or vaccines.
HA-Silicon-Based Composite Microspheres
HA-silicon-based composite microspheres are formed by integrating HA with silicon-based materials, providing superior mechanical strength and adjustable surface properties. Silicon-based materials significantly enhance microsphere stability and enable long-term drug release in vivo and in vitro, with broad applications in biosensors, drug delivery, and tissue engineering.
Hyaluronic Acid Microsphere Preparation Technologies by BOC Sciences
BOC Sciences provides various HA Microsphere preparation technologies, including traditional solvent evaporation and advanced microemulsion techniques. By integrating innovative and mature processes, we have established broad technical advantages in this field. We can offer HA Microspheres with different sizes, functionalities, and customizations tailored to diverse drug delivery and tissue repair applications. Below are the primary preparation techniques we utilize:
Microemulsion Method
The microemulsion method involves dissolving HA in an oil phase, which is then mixed with an aqueous phase and surfactants to form a microemulsion system. By adjusting the composition and stability of the system, we can precisely control the microsphere size, typically ranging from tens of nanometers to several micrometers.
Solvent Evaporation Method
In this method, HA is dissolved in an organic solvent, followed by solvent evaporation to solidify the microspheres. This approach is simple to operate, highly controllable, and produces uniform and stable microspheres.
Spray Drying Method
Spray drying involves atomizing a HA solution into a high-temperature airflow, where the solvent rapidly evaporates, forming microspheres. This technique enables high-speed production, large-scale output, and precise control over particle size and distribution, making it ideal for commercial manufacturing.
Self-Assembly Technology
Self-assembly technology leverages the inherent self-assembling properties of HA molecules under specific conditions to form microspheres with distinct structures and functionalities. By adjusting solvent concentration, temperature, and pH, stable microsphere structures can be created.
Crosslinking Technology
Using chemical crosslinkers such as glutaraldehyde, HA molecules are linked to form a three-dimensional network structure. This enhances mechanical strength and stability, prolonging drug release in the body.
Aqueous Two-Phase Method
The aqueous two-phase method utilizes liquid-liquid partitioning principles, where HA is dissolved in one aqueous phase, forming stable microspheres in another phase. This method allows precise control over microsphere formation and enables tunable size and drug loading by selecting different solvents and conditions.
Supercritical Fluid Technology
Supercritical fluid technology uses supercritical carbon dioxide and other solvents to prepare HA Microspheres. This method offers advantages such as low solvent residue and environmental friendliness, making it ideal for high-quality, functionalized microsphere production.
Electrospinning Method
Electrospinning applies an electric field to stretch a HA solution into nanofibers, which then solidify into microspheres or nanofiber structures. This technique enables the production of high-surface-area and highly porous HA Microspheres, widely used in tissue engineering and drug delivery applications.

What Is the Difference Between Hyaluronic Acid Microspheres and Hyaluronic Acid Gel?
The primary difference between HA microspheres and HA gel lies in their physical form and applications. HA microspheres are solid particles primarily used in drug delivery, tissue repair, and controlled-release applications. Their functionality can be adjusted by modifying particle size, shape, and surface properties. In contrast, HA gel is a highly hydrated soft gel typically used for moisturizing, lubrication, and wound care applications.
