Background:

Nanoparticles show promise for toxin binding and detoxification.
Intravenous nanoparticle administration can cause liver accumulation and secondary poisoning, especially in liver-failure patients.

Purpose of the Study:

To develop a novel, liver-inspired 3D detoxification device.
To create a safe and efficient platform for toxin removal, avoiding liver accumulation.

Main Methods:

3D printing of designer hydrogels incorporating functional polydiacetylene nanoparticles.
Designing a 3D matrix mimicking liver lobule microstructure for efficient toxin trapping.
Utilizing nanoparticles for toxin attraction, capture, and sensing.

Main Results:

The 3D-printed biomimetic device demonstrated efficient toxin trapping.
Treated toxin solutions completely lost their virulence.
Proof-of-concept for detoxification using a 3D-printed nanocomposite hydrogel construct.

Conclusions:

A novel 3D-printed biomimetic nanocomposite hydrogel device offers effective detoxification.
This approach presents a potential alternative to conventional nanoparticle detoxification methods, mitigating risks of liver accumulation.
The study paves the way for developing new detoxification platforms.
