Project description
New solution for efficient cryo-electron microscopy
Cryo-electron microscopy (cryo-EM) has transformed structural biology, enabling atomic-resolution protein structure determination without crystallisation through the imaging of flash-frozen specimens in vitreous ice. Despite the 2017 Nobel Prize recognition, current cryo-EM faces critical limitations: minimum protein size requirements (>50-100 kDa), sample homogeneity constraints and prohibitive costs (upwards of EUR 10 million for a 300 kV system and infrastructure from US/Japanese manufacturers). The EIC-funded ACCESS project radically reimagines this paradigm through 4D-STEM diffraction pattern acquisition, leveraging the EBEAM project's proven ptychographic reconstruction algorithms to achieve semi-atomic resolution of cryo-EM samples at a much lower cost.
Objective
Cryo-electron microscopy has transformed structural biology, enabling atomic-resolution protein structure determination without crystallization through imaging of flash-frozen specimens in vitreous ice. Despite the 2017 Nobel Prize recognition, current cryo-EM faces critical limitations: minimum protein size requirements (>50-100 kDa), sample homogeneity constraints, and prohibitive costs (€10M+ for 300 kV system and infrastructure from US/Japanese manufacturers). ACCESS radically reimagines this paradigm through 4D-STEM diffraction pattern acquisition at 30 kV, leveraging EBEAM's proven ptychographic reconstruction algorithms to achieve semi-atomic resolution of cryo-EM samples at 1/10th the cost.

Topic(s)
Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme
Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
