The Department of Health and Human Services, specifically the National Institutes of Health (NIH), is seeking information from small businesses regarding their capabilities to provide Fiber Photometry Processors, particularly the RZ5P model, which is essential for data acquisition and processing in the study of substance use disorders. The processors will be used to record neurotransmitter activity, such as dopamine, during behavioral experiments and substance administration, contributing to the understanding of substance use disorder mechanisms. Interested small businesses, including those classified as HUBZone, service-disabled veteran-owned, and woman-owned, are invited to submit a capability statement detailing their qualifications and relevant experience by January 29, 2025. For further inquiries, potential respondents can contact Joseph Kennedy at joseph.kennedy@nih.gov or Marlene Milgram at marlene.milgram@nih.gov.
