KAUST researchers led by Dr. Niveen Khashab have developed thermosensitive liposomes for controlled drug release, particularly in cancer therapies. The liposomes are designed to release drugs only when they reach heated tumor tissue, minimizing systemic side effects. Cholesterol moieties are used as anchors to create a "nail" or "comb" effect, enabling temperature-triggered drug release inside cells. Why it matters: This targeted drug delivery system could significantly improve the efficacy and reduce the toxicity of cancer treatments.

KAUST researchers led by Yves Gnanou and Nikolaos Hadjichristidis have developed a metal-free process for creating aliphatic degradable polycarbonates using CO₂. This polycarbonate is transparent, highly flexible, and produced without toxic metals, using an ammonium compound and a boron-based compound. The process helps reduce plastic pollution and CO₂ emissions, addressing environmental concerns. Why it matters: This innovation offers a sustainable alternative to traditional plastic production, aligning with global efforts to reduce reliance on harmful materials and combat climate change.
KAUST researchers presented their work on stabilizing nanoparticle catalysts at the 252nd American Chemical Society Meeting & Exposition. The team devised a "molecular Scotch tape" using a silica gel support coated with a single molecule layer of soft material containing sulfur. This approach allows nanoparticles to stick to one side while leaving the other side free for catalysis, preventing aggregation without killing the catalyst. Why it matters: This innovation in catalyst stabilization could lead to more efficient and sustainable chemical processes, impacting various industries.
KAUST startup Quantum Solutions manufactures quantum dots, semiconducting nanoparticles that emit light with controllable energy.
