Integrated temperature control. Temperature step generator. Left: schematic of PDMS microfluidic device generating a temperature step around a Drosophila embryo. Middle: visualization of the temperature step with thermochromic liquid crystal (green: 21 °C—–red: 28 °C). Right: influence of the temperature step on the embryo nuclear density after 150 min [126].
