The master template design was imported to a Nanoscribe Photonic Professional GT (Nanoscribe, Germany) for direct laser writing or 2PP. The substrate used for 2PP was indium tin oxide (ITO) coated glass slide (Nanoscribe, Germany). A drop of IPS resin (Nanoscribe, Germany) was placed on the surface of the ITO coated glass slide. For laser writing, a 25x objective with a numerical aperture of 0.8 was used for focusing the laser beam. The desired structure was written on the glass slide in a layer-by-layer fashion and monitored using a real-time camera. After completion of the writing process, another drop of resin was added on top of the master template and spin-coated at 6000 rpm for 2 min and annealed at 190 °C for 3 min. An unannealed structure was also fabricated for comparison.

Samples for microendoscope resolution estimates were fabricated using a Nanoscribe Photonic Professional GT2 two-photon polymerization 3D printer. The samples were printed in IP-S resin (Nanoscribe GmbH), an inherently autofluorescent resin that enables high-precision 3D printing of microstructures. We printed two different samples [Fig. S6(b) in the Supplementary Material ]: a sparse structure with an axial resolution (sphere-to-sphere spacing) of and a fine structure with a lateral and axial resolution of for evaluating the image reconstruction. The printing parameters and development time were optimized for the high aspect ratios and small features of these structures.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
