The new open-source software and hardware matrix deposition device named iMatrixSpray was optimized and specified for homogeneity, reproducibility, and sensitivity in MS imaging experiments. The results confirm the design claims, with the device delivering uniform coatings with a constant quality from experiment to experiment. The robustness in combination with the open design allows developing and sharing of matrix deposition and sample preparation protocols between labs. This tool therefore enables researchers to enter the field of MALDI MSI without previous experience in matrix coating.
