“…Any pathological processes in the central nervous system are accompanied by some changes in CSF in terms of the composition and surfactant properties ( Table 6 ). 3 , 78 CSF surface tension of patients with CSF infection, hemorrhage, congenital and tumor hydrocephalus, and CNS malformations has been studied. It is found that the surface tension of CSF is dependent on its protein concentration.…”

Introduction: Pathological features of disease appear to be quite different. Despite this diversity, the common feature of various disorders underlies physicochemical and biochemical factors such as surface tension. Human biological fluids comprise various proteins and phospholipids which are capable of adsorption at fluid interfaces and play a vital role in the physiological function of human organs. Surface tension of body fluids correlates directly to the development of pathological states. Methods: In this review, the variety of human diseases mediated by the surface tension changes of biological phenomena and the failure of biological fluids to remain in their native state are discussed. Results: Dynamic surface tension measurements of human biological fluids depend on various parameters such as sex, age and changes during pregnancy or certain disease. It is expected that studies of surface tension behavior of human biological fluids will provide additional information and might become useful in medical practice. Theoretical background on surface tension measurement and surface tension values of reference fluids obtained from healthy and sick patients are depicted. Conclusion: It is well accepted that no single biomarker will be effective in clinical diagnosis. The surface tension measurement combined with routine lab tests may be a novel non-invasive method which can not only facilitate the discovery of diagnostic models for various diseases and its severity, but also be a useful tool for monitoring treatment efficacy. We therefore expect that studies of surface tension behavior of human biological fluids will provide additional useful information in medical practice.

“…These systems, collectively known as complex fluids, are said to be viscoelastic, as their response to deformation may exhibit characteristics of both elasticity and viscous dissipation. Complex fluids arise frequently in biology – examples include synovial fluid, tear films, lung surfactants and cerebrospinal fluid – and changes in their rheology have been linked to the development and diagnosis of diseased states121314. Microrheology is therefore a powerful emerging tool for biophysics and medical diagnostics1115.…”

Spatially-resolved rotational microrheology with an optically-trapped sphere

We have developed a microrheometer, based on optical tweezers, in which hydrodynamic coupling between the probe and fluid boundaries is dramatically reduced relative to existing microrheometers. Rotational Brownian motion of a birefringent microsphere within an angular optical trap is observed by measuring the polarisation shifts of transmitted light. Data gathered in this manner, in the strongly viscoelastic fluid Celluvisc, quantitatively agree with the results of conventional (bulk) rheometry. Our technique will significantly reduce the smallest sample volumes which may be reliably probed, further extending the study of rare, difficult to obtain or highly nonhomogeneous fluids.

“…Overviews of developments on this subject during the last 15 years were given in [136,137,138]. The studies have demonstrated that dynamic surface tensions can provide very important information of the health state of patients, even when other much more established medical or biochemical diagnostic tools fail.…”

“…Recently, it was demonstrated that the dilational rheology is superior to surface tension as it is more sensitive to the composition of surface active compounds in solution. As examples, in [138] biological liquids like cerebrospinal fluid, expired air condensate and umbilical blood of newborns have been investigated for patients suffering from neurosyphilis. The measured visco-elasticity has shown that these parameters depend significantly on the disease, i.e.…”

Interfaces can be called Smart and Green (S&G) when tailored such that the required technologies can be implemented with high efficiency, adaptability and selectivity. At the same time they have also to be eco-friendly, i.e. products must be biodegradable, reusable or simply more durable. Bubble and drop interfaces are in many of these smart technologies the fundamental entities and help develop smart products of the everyday life.Significant improvements of these processes and products can be achieved by implementing and manipulating specific properties of these interfaces in a simple and smart way, in order to accomplish specific tasks. The severe environmental issues require in addition attributing ecofriendly features to these interfaces, by incorporating innovative , or, sometime, recycle materials and conceiving new production processes which minimize the use of natural resources and energy. Such concept can be extended to include important societal challenges related to support a sustainable development and a healthy population.The achievement of such ambitious targets requires the technology research to be supported by a robust development of theoretical and experimental tools, needed to understand in more details the behavior of complex interfaces. A wide but not exhaustive review of recent work concerned with green and smart interfaces is presented, addressing different scientific and technological fields. The presented approaches reveal a huge potential in relation to various technological fields, such as nanotechnologies, biotechnologies, medical diagnostics, new or improved materials.
