The use of liquid metals based on gallium for soft and stretchable electronics is discussed. This emerging class motivated, in part, by the new opportunities that arise from devices have mechanical properties similar to those encountered human experience, such as skin, tissue, textiles, clothing. These types (e.g., wearable or implantable electronics, sensors robotics, e-skin) must operate during deformation. Liquid are compelling materials these applications because, principle, they infinitely deformable while retaining metallic conductivity. been used wires interconnects, reconfigurable antennas, sensors, self-healing circuits, conformal electrodes.

Chemotherapy is currently one of the most effective ways to treat cancer. However, traditional chemotherapy faces several obstacles clinical trials, such as poor solubility/stability, non-targeting capability and uncontrollable release drugs, greatly limiting their anticancer efficacy causing severe side effects towards normal tissues. Supramolecular integrating non-covalent interactions a highly promising candidate in this regard can be appropriately used for targeted drug delivery. By taking advantage supramolecular chemistry, some limitations impeding applications solved effectively. Therefore, we present here review summarizing progress cancer treatment based on host-guest recognition provide guidance design new targeting combining diagnostic therapeutic functions. Based large number state-of-the-art studies, our will advance basis promote translational applications.

Soft dielectric materials typically exhibit poor heat transfer properties due to the dynamics of phonon transport, which constrain thermal conductivity (k) decrease monotonically with decreasing elastic modulus (E). This thermal-mechanical trade-off is limiting for wearable computing, soft robotics, and other emerging applications that require both high low mechanical stiffness. Here, we overcome this constraint an electrically insulating composite exhibits unprecedented combination metal-like conductivity, compliance similar biological tissue (Young's < 100 kPa), capability undergo extreme deformations (>600% strain).
