Aptamer and Inorganic Nanocarrier Coupling Service

Aptamer and Inorganic Nanocarrier Coupling Service

Aptamers have been identified as candidates for the construction of various smart systems for therapy, diagnosis, bioimaging, and drug delivery due to their high target affinity and specificity. Aptamers are accounted as chemical antibodies that can be readily linked to drugs, sensors, signal enhancers, or nanocarriers for functionalization.

CD Bioparticles provide a customized service for coupling aptamers with inorganic nanocarriers for targeted drug delivery. In recent years, new inorganic nanomaterials are emerging as potential candidates for nanocarriers, showing talent in terms of drug-carrying capacity, stability, and biocompatibility. Our experienced scientists have created a comprehensive technical service to design upon request aptamers for drug delivery coupled to inorganic nanocarriers.

Aptamer and Inorganic Nanocarrier Coupling Service Background

Aptamers are considered to be chemical antibodies that can be easily coupled to drugs, sensors, signal enhancers, or nanocarriers for functionalization and can be flexibly coupled to various nanocarriers by various coupling methods.

In recent years, inorganic materials as nanocarriers have shown great potential for use in drug delivery systems. As the backbone of the system nanocarriers can carry and release drugs, keep the backbone intact during circulation and have good biocompatibility and pharmacological properties. The most commonly studied inorganic nanocarriers are mesoporous silica nanoparticles (MSNs), graphene oxide (GO), black phosphorus (BP), and gold nanoparticles (GNPs). Even some nanomedicines based on inorganic nanocarriers are being evaluated clinically.

Our Coupling Service Strengths

  • Highly Targeted: Aptamer-coupled inorganic nanomaterials have bioimaging potential and exhibit excellent photothermal therapeutic efficacy against tumor cells in a specific manner.
  • Specificity: The service can facilitate research into specific and controlled therapies based on inorganic nanomaterials. A targeted photodynamic therapy (PDT) and photothermal therapy (PTT) reagent has been developed by coupling an aptamer to an inorganic nanomaterial.
  • Synergistic Therapy: Aptamer-inorganic nanomaterial coupling allows for easy synergistic anti-cancer treatment with drugs by encapsulating the combined therapeutic agent.
  • Image Guided Therapy: Aptamer coupling to inorganic nanocarriers enables imaging-guided therapy and can also be used as Raman signals for cellular imaging purposes, demonstrating the feasibility of traceable anticancer applications.
