Inorganic Nanoparticles Development Services

Inorganic nanoparticles, as an emerging drug delivery system (DDS) with unique physicochemical and biological properties, show great promise for targeted drug delivery, controlled release drug delivery, and improved bioavailability, etc.

Protheragen-ING focuses on harnessing the power of inorganic nanoparticles for DDSs. We offer a full range of inorganic nanoparticle drug delivery system development services and can customize inorganic nanoparticle products to meet your needs.

About Inorganic Nanoparticles DDS

Inorganic nanoparticles are promising drug delivery vehicles due to their unique properties and wide range of applications. Their sizes typically range from 1 to 100 nm, and by encapsulating drugs in these nanoparticles, we can overcome biological barriers, extend drug circulation time, and achieve site-specific delivery, ultimately leading to better therapeutic outcomes.

Utilizing inorganic nanoparticles as a DDS has many advantages over traditional methods.

Our Comprehensive Development Services

Our team of experts can assist you at every stage of the nanoparticle development process, from concept to final product. Our services include:

We employ state-of-the-art techniques to design and synthesize inorganic nanoparticles with precise control over their size, shape, and surface properties.

We utilize advanced characterization techniques to thoroughly analyze the physicochemical properties of the developed nanoparticles. This includes particle size distribution analysis, surface charge determination, morphology characterization, and drug loading efficiency assessment.

We specialize in encapsulating various drugs within inorganic nanoparticles, ensuring efficient loading and controlled release properties. We conduct comprehensive release studies to evaluate the release kinetics, stability, and release mechanisms of the encapsulated drugs.

We offer expertise in surface functionalization of inorganic nanoparticles to achieve specific targeting and enhanced cellular uptake. We can assist in the design and incorporation of targeting ligands or stimuli-responsive moieties to achieve site-specific drug delivery and controlled release at the desired location.
