Engaging cancer patients on their attitudes towards microbiome engineering technologies

Microbiome engineering aims to develop engineered live biotherapeutic products to diagnose and treat human disease. One of the most active areas is in the engineering of modified bacteria that act as cancer therapeutics, with many products currently in clinical trials. With the emergence of any novel technologies, it is important to consult the public and end users throughout their development to address any concerns that may arise from their use. This is particularly true for therapeutics, for which it is vital that both clinicians and patients have confidence in the treatments that are available to them. Here, we surveyed a cohort of cancer patients and their relatives to gauge their knowledge of modern microbiome engineering techniques. We focus predominately on the use of bacterial eLBPs to treat cancer. Overall, most participants indicated that they would be comfortable taking cancer treatment options based on microbiome engineering technologies.

Fiberbots: Robotic fibers for high-precision minimally invasive surgery

Technologies that rely on the fundamental principle of thermal expansion have demonstrated high-precision, a growing demand in fields driven by miniaturization. However, scalable production of high aspect ratio devices that harness this capability while facilitating flexibility in design and functionality remains a challenge. We employed the high-throughput fiber thermal drawing technique to readily fabricate multimaterial fiberbots that can precisely and omnidirectionally move by asymmetric thermal expansion. These millimeter-scale fibers (< 2 mm) show excellent repeatability and linearity, negligible hysteresis, and can achieve micron-level resolution over four orders of magnitude motion range. By integrating these robotic fibers with medical devices that can perform cellular-level tissue imaging, diagnosis, and manipulation, we showcase their versatility through benchtop and preclinical animal studies and their overall potential impact on medicine, biomedical engineering, robotics, and beyond. One Sentence SummaryScalable manufacturing and integration of robotic fibers that deliver high-precision motion when heated.
