The Selena neutrino experiment couples an amorphous selenium (aSe) ionization target to a complimentary metal-oxide semiconductor (CMOS) pixel array as an imaging detector for next generation neutrino physics. I will present the R&D status of the first prototype pixel array designed for Selena, the TopmetalSe. The TMSe was fabricated on the Sky130nm Open-Source process and contains a 100x100 charge-sensing pixel array. We've demonstrated it's low-noise (15 e-), high spatial-resolution (15 um) capabilities and will share results from a photoelectric calibration. We've also successfully coupled the TMSe to aSe in a unique package and will share our first tracks.
