| Description | The aim of this work is to develop a new instrument capable of imaging cells live in 3D culture and perform local measurements of the viscoelastic properties of the matrix next to the cells. So far, the team has made significant progresses towards the development of the novel light sheet microscope, and I have been exploring alternative microrheology methods that could complement the one originally suggested in our project, i.e. optical tweezers. These activity has led to the publication of five scientific articles in high impact international journals. Moreover, the team has just published a scientific article that introduce a novel tool for 3D microrheology, which combines Optical Tweezers with Integrated Multiplane Microscopy (OpTIMuM); https://doi.org/10.1038/s41598-021-85013-y. This technology underpins the one originally proposed in the project. Moreover, the dissemination of our achievements has led to establish new collaboration with researchers working at the University of Lincoln in Marine Biology and interested in studying the local viscosity gradients surrounding plankton. We have published a scientific article in PANS (https://doi.org/10.1073/pnas.2011389118). |

| Title | i-RheoFT: Fourier transforming sampled functions without artefacts |
| Description | We have developed a new open-access code named "i-RheoFT" that implements the analytical method first introduced in [PRE, 80, 012501 (2009)] and then enhanced in [New J Phys 14, 115032 (2012)], which allows to evaluate the Fourier transform of any generic time-dependent function that vanishes for negative times, sampled at a finite set of data points that extend over a finite range, and need not be equally spaced. I-RheoFT has been employed here to investigate three important experimental factors: (i) the 'density of initial experimental points' describing the sampled function, (ii) the interpolation function used to perform the "virtual oversampling" procedure introduced in [New J Phys 14, 115032 (2012)], and (iii) the detrimental effect of noises on the expected outcomes. We have demonstrated that, at relatively high signal-to-noise ratios and density of initial experimental points, all three built-in MATLAB interpolation functions employed in this study (i.e., Spline, Makima and PCHIP) perform well in recovering the information embedded within the original sampled function; with the Spline function performing best. Whereas, by reducing either the number of initial data points or the signal-to-noise ratio, there exists a threshold below which all three functions perform poorly; with the worst performance given by the Spline function in both the cases and the least worst by the PCHIP function at low density of initial data points and by the Makima function at relatively low signal-to-noise ratios. We envisage that i-RheoFT will be of particular interest and use to all those studies where sampled or time-averaged functions, often defined by a discrete set of data points within a finite time-window, are exploited to gain new insights on the systems' dynamics. |
