NYU Abu Dhabi Develops Cancer-Fighting Nanospheres
The biotech breakthrough promises safer and more effective treatments using photodynamic and photothermal therapies.
A Research team from NYU Abu Dhabi’s Magzoub lab has made considerable advances in the fight against cancer using biocompatible nanospheres that have the potential to replace traditional forms of treatment.
The experiments trialed photodynamic therapy (PDT) and photothermal therapy (PTT), which use non-invasive light waves to destroy cancers, avoiding the well-known side effects of chemo and radiotherapy.
Photodynamic therapy works by releasing a torrent of reactive oxygen species (ROS) onto cancer cells, whereas photothermal therapy converts light into searing heat, destroying tumor tissues through hyperthermia.
The research team has detailed their findings in a paper entitled “pH-Responsive Upconversion Mesoporous Silica Nanospheres for Combined Multimodal Diagnostic Imaging and Targeted Photodynamic and Photothermal Cancer Therapy”. The literature goes on to explain how the nanospheres are able to protect encapsulated photosensitizers and photothermal agents from degrading, enabling them to be delivered directly to cancer cells.
Alongside thermal and fluorescent imaging, traditional magnetic resonance imaging (MRI) is also used for tumor detection and monitoring. Once cancer is detected, the PDT and PTT can kill tumors without leaving toxic traces in the body.

Loganathan Palanikumar, a senior researcher in the NYUAD Magzoub lab, explained the process, “To make PDT effective, we need enough photosensitizer in the tumor tissue, while PTT requires a substantial accumulation of photothermal agents within tumors”.
Mazin Magzoub, NYUAD associate professor of biology and Magzoub lab leader, added, “New therapeutic approaches are desperately needed to enhance the existing arsenal of cancer-fighting treatments”.
Magzoub lab’s new treatments offer real hope that cancers could soon be treated with minimal stress and danger to patients, leading to a brighter future free from one of the world’s most feared and destructive diseases.

Joby To Establish All-Electric Air Taxi Ecosystem Across The UAE
The comprehensive agreement with Abu Dhabi’s government includes a training program, infrastructure development, and a manufacturing presence.
All-electric aircraft company Joby Aviation has secured three separate agreements with departments of Abu Dhabi’s government that lay the groundwork to develop and scale air taxi services in the Emirate and beyond.
The deal was signed at the recent DRIFTx thought-leadership and exhibition platform and gave Joby exclusive rights to not only operate air taxi services in Dubai but also unlock inter-emirate services between Abu Dhabi.
Joe Ben Bevirt, founder and CEO of Joby Aviation, said: “Today’s agreement demonstrates the incredible momentum behind the adoption of clean flight across the UAE. We’re looking forward to delivering a fantastic experience for our future customers in Abu Dhabi and we’re excited to be unlocking the potential for zero-emissions flight between Abu Dhabi and Dubai. We’re grateful for the support and collaboration of our governmental partners and the entire ecosystem in Abu Dhabi and we remain deeply impressed by their commitment to building out a world-class aviation ecosystem in the Emirate”.
Joby’s all-electric aircraft went on display for the first time in Abu Dhabi’s Yas Marina at the DRIFTx event. The air taxi is designed to carry a pilot and four passengers and can reach speeds of 200 miles per hour (321 km/h). The zero-emission craft is said to have an extremely low acoustic footprint and can travel a maximum of 100 miles (161 km) on a single charge.

Once operational, Joby’s air taxi fleet would enable fast, clean travel across the UAE, with journeys between Abu Dhabi to Dubai taking just 30 minutes compared with two hours by car during peak times.
Joby continues to work closely with the UAE’s General Civil Aviation Authority (GCAA) to help the Emirates become a world leader in the introduction of air taxis. Additional testing and analysis will be required before inter-emirate travel becomes a reality, but the cutting-edge technology already appears to have great potential.
