(a) Photograph of the device with no applied deformation (left) with the corresponding microscopy image of the EGaln in microfluidic channel (right). (b) Photograph of the device being stretched in a direction parallel to the channel (left) with the corresponding microscopy image showing that the EGaln confinement was well maintained within the channel (right). (c) Photographs of the device as it underwent different forms of user applied deformation: twisting, bending and compressing. (d) Photograph of the same device after it went through all the different mechanical deformations (left) with the corresponding microscopy image showing the integrity of the EGaln confinement within the microchannel (right).
