Cell-Adjuvant-loaded Nanoparticles (NP) Conjugate Service

The main limitation of cell-based therapies is the viability and function of transplanted cells. After cell transfer, therapeutic cells often rely on adjuvants, such as the simultaneous delivery of drugs. These adjuvants are designed to maximize the donor cell efficacy, phenotype and / or durability in vivo.

Here at Creative Biolabs, we developed a method via the conjugation of adjuvant–loaded nanoparticles to the surfaces of therapeutic cells to enhance cell therapy. This approach is a simple and generalizable strategy to augment cytoreagents while minimizing the systemic side effects of adjuvants.


Types of Conjugates

Peptide-loaded NP
Antibody-loaded NP
Drug-loaded NP
Vaccine-loaded NP
Nucleic Acids-loaded NP
Fluorescent-loaded NP

NP design and synthesis

Nanoparticles have many applications in biology and medicine and are used as biosensors, cell probes, and drug delivery vehicles. In order to achieve these specific applications of nanoparticles, it is necessary to have the ability to design the shape, size, and modify of the surface of NPs.

Creative Biolabs has extensive expertise in the design and synthesis of adjuvant-loaded NP. We provide high-quality customized NP design services and peptide synthesis services for research, diagnostic, pre-clinical and commercial applications.

Customization Capabilities:

Composition A variety of metals, oxides, semiconductors and polymer nanomaterials are avalible. We also provide assistance with existing protocols for process optimization, scale-up and cGMP-compliant manufacturing.
Size We can produce a variety of particle sizes and other sizes can be customized as required. We can also produce polymers up to 1 µm in size, oxide particles and core / shell structures.
Surface Our standard nanoparticles have a variety of available anionic and cationic end-capping ligands. In addition, we can manufacture nanomaterials with specific functional groups, polymers, and biomolecules.
Concentration We have developed techniques for processing and stabilizing high-concentration particles. UV-visible spectroscopy and ICP mass spectrometry are used to accurately measure material concentration and extinction coefficient.



"One-Step in Minutes"

Based on our CellFace™ conjugate technology platform, we utilize fucosyltransferases (Fuc T) to transfer NP to the surface of living cells in minutes. This one-step approach developed by scientist team is a fast, simple, and cost-effective technique for cell surface engineering. Using this method, any adjuvant-loaded NPs can be introduced to the cell surface without genetic modification of the host cells.
