Other Environmentally Sensitive Hydrogel Development

At CD Formulation, our environmentally sensitive hydrogel development services offer comprehensive solutions for the design and formulation of advanced hydrogels with stimuli-responsive properties. Our expertise lies in selecting and tailoring environmentally sensitive materials and polymers to achieve the desired responsiveness.

Environmentally Sensitive Hydrogels for Peptide & Protein Delivery

As a result of environmental cues such as enzymes, ROS, and electrical fields, environmentally sensitive hydrogels exhibit significant changes in their physical properties. These hydrogels are designed to undergo reversible swelling or shrinking, leading to the controlled release of encapsulated peptides and proteins. By leveraging stimuli-responsive behavior, environmentally sensitive hydrogels offer advantages in terms of targeted and triggered drug delivery.

Hydrogel releases antimicrobial peptides in response to matrix metalloproteinases (MMPs) and reactive oxygen species (ROS) (Jeong S.H.; et al. 2023)

What Can We Do for Environmentally Sensitive Hydrogel Development?

• Enzyme-Sensitive Hydrogel Development

At CD Formulation, we specialize in designing hydrogels that respond to specific enzymes, allowing for the controlled release of therapeutics at the desired site. Our expertise extends to various enzymes, including matrix metalloproteinases (MMPs), proteases, hyaluronidases and esterases. Through our tailored approach, we enable efficient and localized delivery of drugs, enhancing therapeutic efficacy while minimizing off-target effects.

• Magnetic-Sensitive Hydrogel Development

CD Formulation offers a comprehensive magnetically sensitive hydrogel development program. By encapsulating magnetic nanoparticles such as iron oxide (Fe₃O₄) or cobalt ferrite (CoFe₂O₄) within temperature-responsive polymer networks composed of materials like poly(N-isopropylacrylamide) and poly (ethylene glycol), we are able to design novel hydrogels whose permeability and drug release rates can be non-invasively controlled via application of an external magnetic field.

• Redox-Sensitive Hydrogel Development

CD Formulation specializes in designing hydrogels that respond to specific redox conditions, allowing for the targeted release of therapeutics. By incorporating redox-responsive materials such as disulfide bonds, selenocysteine, or thioketal linkages, we create hydrogels that undergo reversible gelation or degradation in response to redox stimuli. Our expertise extends to the utilization of redox-sensitive polymers like polyethylene glycol diacrylate (PEGDA) and poly (ethylene glycol)-co-poly (propylene sulfide) (PEG-PPS) copolymers.

• Multi-Sensitive Hydrogel Development

CD Formulation offers a multi-sensitive hydrogel development program where we combine two or more stimulus-responsive mechanisms into a single hydrogel matrix. For example, by copolymerizing pH-responsive acrylic acid with thermo-responsive PNIPAAM or using a combination of temperature-sensitive and ion-sensitive materials to encapsulate active ingredients, different purposes such as increasing the mechanical strength of the gel and accelerating the gelation speed can be achieved.
