“…The first peak, in the range of wavevectors 0.10-0.15 nm À1 , provides information related to the size of the liposome, whereas the second one appears at higher values of q (around 2 nm À1 ), and provides information related to the thickness of the membrane, i.e., the thickness of the hydrophobic chains of the lipid molecules [33]. On one side, the intensity of the first peak on the SANS reflectivity profile decreases with the increase of the liposome size, which is ascribed to the decrease of the resolution of SANS as the size of the scatters increases [34]. On the other side, the peak corresponding to the membrane thickness appears well-defined independently of the liposome size, having a value of about 4 nm as reported in Table 1.…”

“…Optical or confocal microscopes provide snapshots of the system with sub-micron resolution, but they are limited in terms of size of the field of view and viable samples (mostly particle-based and optically transparent). Advanced scattering methods [268] allow for time-and space-resolved measurements of the structure and dynamics on macroscopic portions of the sample and for a large variety of systems (figure 19(C)). However, spatial mapping is coarsened over tens of microns and data interpretation is less straightforward than for imaging.…”

Soft materials are usually defined as materials made of mesoscopic entities, often self-organized, sensitive to thermal fluctuations and to weak perturbations. Archetypal examples are colloids, polymers, amphiphiles, liquid crystals, foams. The importance of soft materials in everyday commodity products, as well as in technological applications, is enormous, and controlling or improving their properties is the focus of many efforts. From a fundamental perspective, the possibility of manipulating soft material properties, by tuning interactions between constituents and by applying external perturbations, gives rise to an almost unlimited variety in physical properties. Together with the relative ease to observe and characterize them, this renders soft matter systems powerful model systems to investigate statistical physics phenomena, many of them relevant as well to hard condensed matter systems. Understanding the emerging properties from mesoscale constituents still poses enormous challenges, which have stimulated a wealth of new experimental approaches, including the synthesis of new systems with, e.g., tailored self-assembling properties, or novel experimental techniques in imaging, scattering or rheology. Theoretical and numerical methods, and coarse-grained models, have become central to predict physical properties of soft materials, while computational approaches that also use machine learning tools are playing a progressively major role in many investigations.This roadmap paper intends to give a broad overview of recent and possible future activities in the field of soft materials, with experts covering various developments and challenges in material synthesis and characterization, instrumental, simulation and theoretical methods as well as general concepts.

“…Since the size of (relatively large) colloids is at least a few hundred nanometers, i.e., about the wavelength of light, the structure and dynamics of colloidal dispersions can be experimentally studied by means of scattering techniques [60,61], namely, light, x-ray and neutron scattering methods. Single colloidal particles can also be observed by confocal and conventional (optical) microscopy [11,62].…”

Colloidal soft matter is a class of materials that exhibit rich equilibrium and non-equilibrium 0thermodynamic properties, it self-assembles (spontaneously or driven externally) to form a large diversity of structures, and its constituents display an interesting and complex transport behavior. In this contribution, we review the essential aspects and the modern challenges of Colloidal SoftMatter Physics. Our main goal is to provide a balanced discussion of the various facets of this highly multidisciplinary field, including experiments, theoretical approximations and models for molecular simulations, so that readers with various backgrounds could get both the basics and a broader, more detailed physical picture of the field. To this end, we first put emphasis on the colloidal physics, which allows us to understand the main driving (molecular and thermodynamic) forces between colloids that give rise to a wide range of physical phenomena. We also draw attention to some particular problems and areas of opportunity in Colloidal Soft Matter Physics that represent promising perspectives for future investigations.
