A team from the University of Mississippi presents a breakthrough in oncology: a 3D-printed implant that functions as a local chemotherapy reservoir. Designed to be placed after tumor removal surgery, it releases the drug in a controlled manner at the tumor site. This approach aims to maximize the effect on residual cells and reduce the systemic side effects common in traditional treatments.
Manufacturing by SLS and Controlled Release 🔬
The device is manufactured using selective laser sintering, a 3D printing technique that fuses polymer particles with a laser. The resulting material is biodegradable and features a custom-designed porous structure. This porosity regulates the diffusion of the chemotherapeutic agent, allowing for sustained release over an extended period directly into the tumor bed, where it is most needed.
The Tumor Doesn't Get a Farewell Party 🎉
It seems the strategy of attacking the whole body to finish off a few rebel cells is on its last legs. Now, instead of a general bombardment, a persistent and heavy-handed neighbor is installed right in the tumor's neighborhood. It's as if, after kicking out the intruder, we left a security guard handing out fines slowly but relentlessly. A more elegant solution, no doubt.
