Inorganic Nanocarriers Strategy for PNA Delivery

Inorganic Nanocarriers Strategy for PNA Delivery

Inorganic nanomaterials have become ideal materials for drug delivery systems due to their good stability, excellent biocompatibility and high drug loading capacity. Creative Peptides provides solutions for the application of commonly used inorganic nanomaterials such as silica nanoparticles and porous silicon nanoparticles in PNA delivery, and promotes the application of inorganic nanocarriers in the development of PNA drugs.

Applications of Inorganic Nanocarriers in PNA Delivery

Porous inorganic nanocarriers can be dispersed in water and have a suitable size, and can be used for co-delivery of different types of molecules, because their cavities can contain small drugs and can be decorated with elements that can recognize biological macromolecules on their surfaces. We have listed some examples of inorganic nanocarriers that have been used for PNA delivery for reference.

Type of inorganic nanocarriersType of PNADelivery procedure
Zeolite-L nanocrystalsPNA derivativesPNA derivatives are covalently attached to the surface of zeolite-L nanocrystals and co-delivered with small molecules such as DAPI, which are released after PLL degradation.
Mesoporous silica nanoparticlesAnti-miR221 PNAPNA is adsorbed to MSNP loaded with the chemotherapeutic agent temozolomide.
Porous silicon nanomaterialsAnti-miR122 PNAThe anti-miR122 PNA was loaded into pSiNPs by physical adsorption, and then the particles were electrostatically coated with the polymer PEG-DB.
2D Mg-Al layered double hydroxidesPNA targeting KRAS G12D mutant geneWhen the two are combined, the proton sponge effect produced by the nanoparticles occurs and promotes the release of PNA from the endosome.

Synthetic Strategy

Although the chemical composition of inorganic nanoparticles is quite different, their synthesis methods have many similarities. We mainly provide two methods for the synthesis of inorganic nanocarriers and PNA.

  • Chemical conjugation

    Most PNAs can be directly bonded to the coating molecules or polymer scaffolds on the surface of nanoparticles. Molecular linkers are usually combined with nanocarriers, and molecular linkers can be degraded by enzymatic cleavage, hydrolysis or heating.

  • Physical adsorption

    PNA can be encapsulated in a nanotube carrier through hydrophobic interaction, electrostatic interaction or physical capture, and the encapsulated PNA can be released after the disintegration of nanoparticles triggered by cellular uptake or external signals.
