Summary: The development of cell regeneration scaffolds requires biocompatibility and mechanical properties for tissue engineering. Nanofillers and essential oils have allowed the creation of new structures that promote cell proliferation and tissue regeneration. This study prepared membranes using polylactic acid (PLA), polycaprolactone (PCL), titanium dioxide nanoparticles (TiO2-NPs), and orange essential oil (OEO) through drop-casting. The inclusion of TiO2-NPs and OEO in the membranes demonstrated their potential for biomedical applications, as they enhanced tissue regeneration and reduced inflammatory infiltrate.

Summary: Soft continuum robots and manipulators (SCRaMs) are elongated structures used in various applications. The use of multiple actuators in multi-segment SCRaMs increases cost and complexity while reducing reliability. This paper presents a methodology to reduce the number of actuators employed by SCRaMs while maintaining their volumetric workspace. By using one rotary and two linear actuators, the method achieves a significant reduction in the total number of typically employed actuators. This reduces cost and complexity while improving efficiency and reliability.
