For the experiments showing the deprotection of acid labile groups we f unctionalized circular microscope slides of 1 cm diameter as shown in f ig 7. The glass slides were cleaned using isopropanol and acetone and blow dried with nitrogen gas. They were activated using an UV Ozone treatment f or 30 min and immersed in a solution of 5% APTES in 40ml of absolute ethanol at 50 degrees overnight. The samples were cleaned and placed in a solution of PyBOP 742mg, BOC -150mg, DIEA-248ul, DCM 7.5ml (preactivated for 10mins). Samples were kept in the above solution overnight at room temperature, closed with aluminum f oil. The growth of the f ilm was followed by water contact angle and XPS (details in the SI.6). For each experiment, a f unctionalized glass was mounted in the upstanding lid of the platform, using a dedicated glue. Following the experiments, the glasses were removed f rom the platf orm and stained with Rhodamine B isothiocyanate to observe the deprotection f ingerprint.
