BRAIN TARGETED DELIVERY

B-NNP

Dual-targeting mechanism designed for robust Blood-Brain Barrier (BBB) crossing. Enables highly efficient systemic delivery beyond brain vasculature directly into deep parenchymal cells.

RNA Loading

External Loading

High-efficiency plug-and-play loading of oligonucleotides (ASO, siRNA) directly to the NNP surface.

Endogenous Loading

Internal Loading

Stable intracellular transport and functional release of complex macromolecules including therapeutic enzymes.

Endosomal Escape

Cytoplasmic Delivery

Engineered to ensure robust endosomal escape, enabling complete cytoplasmic delivery of therapeutic payloads.

CD47-Guided Immuno-Delivery Platform

I-NNP

I-NNP targets CD47-high diseased tissues in inflammation, fibrosis, and autoimmunity, combining CD47-SIRPα blockade with therapeutic payload delivery in one nanoparticle.

CD47-High Tissue Targeting

Active Homing

I-NNP uses surface SIRPα to bind CD47-high diseased cells, enabling active homing to inflammatory, fibrotic, and autoimmune tissue sites.

SIRPα-CD47 Blockade

Built-in Immune Modulation

By blocking the CD47-SIRPα "don't eat me" signal, I-NNP adds immune-modulating activity directly into the delivery carrier.

Disease-Tailored Payloads

ASO · siRNA · Protein

The same CD47-guided carrier can be adapted with ASO, siRNA, or protein payloads to build disease-specific therapeutic pipelines.
