Abstract

A method of manipulating and/or investigating cellular bodies (9) is provided. The method comprises the steps of: providing a sample holder (3) comprising a holding space (5) for holding a fluid medium (11); providing a sample (7) comprising one or more cellular bodies (9) in a fluid medium (11) in the holding space (5); generating an acoustic wave in the holding space exerting a force (F) on thesample (7) in the holding space (5). The method further comprises providing the holding space (5) with a functionalised wall surface portion (17) to be contacted by the sample (7) and the sample (7) is in contact with the functionalised wall surface portion (17) during at least part of the step of application of the acoustic wave. A system and a sample holder (3) are also provided.

Description

Technical field [0001] The present disclosure relates to methods and systems for studying biological cells. Background technique [0002] Biological cells have outer membranes. This membrane is the interface between the cell and its environment. Therefore, the membrane provides a platform for multiple processes involving membrane embedding of biomolecules, allowing the biomolecules to physically contact the binding partners in the extracellular space. [0003] Therefore, a variety of techniques have been developed for studying cellular and subcellular processes through interaction with cell membranes, and some techniques have been designed to quantify cell surface components to obtain specific cell types (for example, with or without invasion). Breast cancer cells). Most technologies require physical contact with cells. However, a variety of force field technologies have recently been developed, but these technologies often require foreign objects to adhere to cells and / or damag...
