SCP-Nano: A new technology to visualize banocarriers in cells and tissues

How can we ensure that life-saving drugs or genetic therapies reach their intended target cells without causing harmful side effects? Researchers at Helmholtz Munich, Ludwig-Maximilians-Universität (LMU) and Technical University Munich (TUM) have taken an important step to answer this question. They have developed a method that, for the first time, enables the precise detection of nanocarriers – tiny transport vehicles – throughout the entire mouse body at a single-cell level. This innovation, called “Single-Cell Profiling of Nanocarriers” or short “SCP-Nano”, combines advanced imaging with artificial intelligence to provide unparalleled insights into the functionality of nanotechnology-based therapies. The results, published in Nature Biotechnology, pave the way for safer and more effective treatments, including mRNA vaccines and gene therapies.

The Role of Nanocarriers in Modern Medicine

Nanocarriers will play a central role in the next wave of life-saving medicines. They enable the targeted delivery of drugs, genes, or proteins to cells within patients. With SCP-Nano, researchers can analyze the distribution of extremely low doses of nanocarriers throughout the entire mouse body, visualizing each cell that has taken them up. SCP-Nano combines optical tissue clearing, light-sheet microscopy imaging, and deep-learning algorithms. First, whole mouse bodies are made transparent. After the three-dimensional imaging of whole mouse bodies, nanocarriers within the transparent tissues can then be identified down to the single-cell level. By integrating AI-based analysis, researchers can quantify which cells and tissues are interacting with the nanocarriers and precisely where this occurs.
