The National Institutes of Health (NIH) is conducting a market survey to identify qualified small businesses capable of supplying a Nikon AX R confocal microscope system with NSPARC detector technology or an equivalent. The system must support ex vivo imaging of mouse cochleae for dendritic function studies, including calcium, neurotransmitter, and voltage imaging with simultaneous patch-clamp electrophysiology. Key requirements include an upright microscope configuration, single-photon sensitivity, compatibility with high-numerical-aperture water-dipping objectives, and super-resolution capabilities (approximately 100 nm lateral, 300 nm axial). The intended procurement falls under NAICS code 334516, and respondents must submit a capability statement demonstrating their experience and technical capability. Capability statements are due via email by 5:00 PM EDT on June 24, 2026.
