What is it? Why is it important?

Upon study completion and the analysis of the study Biological Material (BM), potential amounts of BM might remain unused in the biobank.


Leftover BM can serve for “Further-Use” purposes, where alternative researchers are given access to the BM. These are research projects that make “Further-Use” of already collected:

  • Biological Material (BM)
  • Health-related personal data (HrPD)


Specific requirements apply for the “Further-Use” of BM in alternative research projects, such as to only share leftover BM:


Researchers planning a research project with “Further-Use” BM must submit the project to EC for approval. Reasons include that leftover BM will be used in projects outside the scope of the study protocol under which the BM was collected

What do I need to do?

Set-up a request process for alternative researchers wanting to access leftover BM from your study. Still, reaching out to the research community can be difficult. It is therefore highly recommended to join the NExT for biobanks platform managed by the Swiss Biobanking Platform (SBP).


Through NExT the SBP:

  • Gives visibility to your biobank and samples
  • Interconnects with the research community
  • Networks with biobanks nationally


By joining the NExT you become connected with researchers and partner biobanks. You can:

  • Choose which Biological Material / biological Specimens to share
  • Decide with whom to share
  • Acknowledge researchers sharing requirements
  • Fully control the agreement terms


In order to ensure the quality of shared BM, the SBP requires you to obtain at least one SBP Quality Label (SBP-Labels). With a SBP-Label your biobank will be included on the NExT platform and become visible to potential researchers.
