A KAUST team discovered a simple method to fabricate microspheres using block copolymer self-assembly. The resulting particles have pH-responsive gates and a highly porous structure, granting them ultrahigh protein sorption capacity. The team leveraged their expertise in block copolymers and self-assembly to achieve this. Why it matters: This new method and the resulting particles have potential applications in biotechnology, medicine, and catalysis, advancing materials science in the region.
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.
Dr. Laurent A. Lantieri delivered a keynote address at KAUST on April 17, 2017, discussing microsurgical procedures. The address included a brief history of microsurgery. The event took place in the University Auditorium. Why it matters: Such events expose the KAUST community to advances in specialized medical fields and potential research applications.
KAUST researchers studied microplastic distribution in the open ocean during a recent expedition. They found microplastics everywhere but in 100 times lower quantities than expected based on production estimates. The study found larger plastic debris at expected levels, but smaller microplastics were disappearing, suggesting they are either sinking or entering the marine food chain. Why it matters: This research highlights the urgent need to understand the fate of microplastics in marine ecosystems and their potential impact on marine life and human health.
KAUST startup Quantum Solutions manufactures quantum dots, semiconducting nanoparticles that emit light with controllable energy. These dots are being explored for applications including displays, photodetectors, and solar cells. Quantum dots can enhance the efficiency of silicon solar panels by absorbing infrared light. Why it matters: This highlights the potential of KAUST-incubated startups to contribute to advanced materials science and renewable energy technologies in the region.
Researchers at KAUST and Peking University Third Hospital have created a novel blastoid model for studying early human development using extended pluripotent stem cells (EPSCs). The blastoid is a 3D cell model mimicking the blastocyst phase, avoiding ethical concerns associated with using human embryos. The team showed that blastoids can be cultured to mimic post-implantation development, offering insights into early cell lineages. Why it matters: This innovation provides a way to study human embryogenesis without the ethical constraints of using actual embryos, potentially advancing our understanding of miscarriage and birth defects.
KAUST and Leica Microsystems inaugurated a Center of Excellence (CoE) for Optical Microscopy on March 12. The partnership aims to drive the use and implementation of advanced imaging systems for life science and materials research. KAUST expects this collaboration to significantly contribute to developments in these areas, benefiting both the university and the Kingdom. Why it matters: This center will enhance KAUST's research capabilities and support Saudi Arabia's scientific development objectives in life sciences and materials research.
A KAUST team led by Husam Alshareef has developed a microfabricated energy storage device with high energy and power density. The device uses nickel hydroxide as an active electrode material and achieves a volumetric capacitance density of 325 F/cm3. Fabricated using chemical bath deposition at room temperature, the device can power microelectronic devices. Why it matters: This research advances energy storage technology in the region, potentially impacting the development of microelectronics and portable power solutions.
