Soft lithography methods are emerging as useful tools for high-resolution, three-dimensional patterning of polymers and nanoparticles. However, the low Young's modulus of the standard template material, poly(dimethylsiloxane) (PDMS), limits attainable resolution, fidelity, and alignment capability. While much research has been

It has been demonstrated that volatile anaesthetics have cardioprotective properties during open-heart procedures, especially when administered continuously. European Council Directive 93/42/EEC concerning medical devices bans the supplementary incorporation of anaesthetic vaporizers in the bypass circuit. Since the uptake of volatile
