Proposal Submission Process

The Brazilian National Nanotechnology Laboratory (LNNano) hosts Brazilian and foreign researchers who wish to use the Laboratory’s experimental stations to carry out their investigations.
The submission of proposals for 2021 must be done through the User Portal.


For 2022, proposal submissions will be carried out exclusively through our new SAU online  system.

(Attention) The submission of proposals for Electron Microscopy and Cryomicroscopy, which have a flow per period, and will be opened in November/21 for execution in 2022, must be done through SAU online 

If the user does not have a record in this new system, it will be necessary to create one.

Exceptional service practices for CNPEM users during the pandemic:

During the period of the COVID-19 pandemic, the CNPEM has adopted exceptional care protocols to protect its researchers and users, seeking to reduce the dissemination of the coronavirus. These rules reinforce CNPEM’s commitment to serving the scientific community, always seeking to ensure the health of all users and its employees.

LNNano-specific user policy

At LNNano, the following facilities are open for remote experiments upon samples postage: Atomic force microscopy and synthesis (MFAS), Micro-Nano Fabrication (MNF), X-ray Microtomography (MicroCT), X-ray excited Photoelectron Spectroscopy (XPS), Electronic Microscopy (fast-track proposals only) and Cryomicroscopy (fast-track proposals only). Services offered by other facilities are still to be determined.

Rules and Tips for the Submission of Proposals

The inclusion of students (masters, doctorate, etc.) in the proposals is encouraged. However, students cannot submit a proposal without a Senior Investigator as the Principal Investigator.
If the proposal is presented by a doctoral student, it must contain a senior researcher, preferably the student’s advisor as to the project’s main researcher.


Important: The proposal submission process is exclusively applicable to research aimed to remain in the public domain, conducted by Brazilian or foreign academic users, or by industrial users who do not seek the intellectual protection of their research.

Types of Proposal

There are two ways to submit research proposals:

– Standard Proposal – for all facilities;
– Fast-Track Proposal – for specific facilities.

Standard Proposal

This is the standard procedure for accessing LNNano facilities. The submission of proposals is carried out following the submission schedule of each facility. The user requests time for a specific experiment in a facility. The proposal is evaluated by one of the Internal or External Proposal Evaluation Committees.

If the proposal is approved, the user is given a limited amount of time to perform research.

Fast-Track Proposal

This procedure aims to improve access to LNNano facilities for experiments that require little preparation and involve simple samples and safety requirements. The Fast–Track process is aimed at users who are experienced in the required technique and whose group, or principal investigator, has already had a proposal submitted and accepted. This procedure can be used to complete and/or complement experimental results for a scientific publications or thesis work. It is necessary for the principal investigator to verify the technical feasibility of carrying out the proposal with the facility coordinator before submission.

For guidelines on submitting fast track proposals for Electron Microscopy/Cryomicroscopy click on Rules_FastTrack, and to fill in the submission form, click on Fast Track_January.docx

Not all LNNano facilities offer the option of submitting fast-track proposals.

How to Submit a Proposal

To start the proposal submission process, the user must register in the User Portal system. To create an account on the portal, the user must enter a valid email address and click on the “access” button. On their first access, the user must provide personal and professional information.

Important: This registration only needs to be done once. It can be done regardless of the proposal submission period and the information provided can be updated at any time.

Once registered in the User Portal system, the user must click on the link “Research proposal-Submission and preparation” and follow the indicated instructions, choosing the National Laboratory and the installation for submission. You will need to fill out a general form online.

After submission, the proposal will be automatically forwarded to the User Support Service (SAU).

Analysis of the Research Proposal

The research proposal analysis process is divided into different phases:

Phase 1: Internal evaluation of the proposal by the facility coordinator to judge the technical feasibility of the proposed experiment.

Phase 2: The facilities’ Internal Committees and External Proposal Evaluation Committees evaluate and rank the proposals according to the following criteria: scientific merit of the proposals and experience of the team, evaluation of previous proposals and scientific publications based on results obtained previously at LNNano. The highest rated proposals are recommended for receiving facility usage time.

Phase 3: Internal assessment by the safety committee, the proposal that presents a safety risk for execution will have to fill out a specific safety form and undergo an assessment by a safety committee that will make recommendations for carrying out the experiment.

Important: Given the importance of scientific track record for the prioritization process, it is recommended that users check and update their publications both in the User Portal system and in the CNPEM Library database. Updates to the library’s database must be made by sending the complete bibliographic information to the Library ( The publications are included after being checked by the library staff and facilities’ coordinators.

Rules and Tips for Submission of Proposals

The research proponent must hold a PhD. After the user’s registration in the User Portal system, the submission pages will be available only to researchers with a PhD.

Important: The inclusion of master’s and doctoral students, as well as postdoctoral fellows in the proposals is encouraged. However, students and fellows cannot submit proposals. The proposal must be submitted by the group’s principal investigator.

TIP: Before submitting a proposal, it is recommended that users consult the website for available facilities, courses, services and technologies, as well as specific recommendations for sample preparation, protocols and further research proposal submission guidelines. Consulting the facility coordinator for information is also highly recommended.
