Phagocytosis is defined as the receptor-mediated uptake of large particulate matter. This process is particularly efficient in specialized immune cells such as macrophages, neutrophils and dendritic cells. These cells constitute the first line of defense against invading
The integration of multiferroic materials in the new generation of nanostructured electronic devices requires precise and orderly control of the thin films growth, taking into account the nature of such materials to develop domain structures, that is,
Cellular mechanics are of prime importance in the birth and the evolution of tumors towards increasingly aggressive stages and are often proposed as potential biomarkers to evaluate metastatic potential. Mechanical properties of two human prostate cell lines,
In recent years, the folding and unfolding of single macromolecules has been largely investigated through atomic – force microscopes (AFM), laser optical tweezers (LOT) and magnetic tweezers (MT), which are able to apply external forces directly to
Brewster angle microscopy (BAM) is an imaging technique that allows for the visualization of the film architecture of monolayers without the use of exogenous dyes. This is a relatively new system that was developed independently and concurrently
Inflammation is the protective response of the immune system that aids the removal of invading infectious agents and repair tissue injury. It involves the movement of white blood cells (leukocytes) from the bloodstream, through the cells lining
MFM is an extended measurement function of the tapping-mode scanning and lift-mode controlling modes of atomic force microscopy (AFM), where the magnetic domain image is obtained by detection of magnetic force gradient changes between a magnetic tip
Is it possible to overcome microscopic contamination affecting the interpretation of the archaeological record?
Archaeology is a subfield of anthropology, the study of all human culture. This discipline often resorts to several scientific techniques to analyse the archaeological record. For instance, microscopy is intensively used to analyse different materials, such as
While our eyes are open they are constantly exposed to bacterial infections, injury, and dehydration. To provide the necessary protection against these hazards the outer surface of our eyes is covered by a thin layer known as
Bacteria interact with our bodies every day, resulting in both positive and negative outcomes. We rely on the billions of beneficial bacteria in our microbiome to support our digestion and immunity. At the same time, pathogenic bacteria
Diagnosis of disease is the fundamental goal of medicine as treatment and prognosis rely on it. The diagnostic process ends eventually with tissue sampling (biopsy) for microscopic evaluation. The paradigm “tissue is the issue” reflects the modern trend
As we all know, DNA is the matrix for the proteins and the proteins are the molecules which are involved in every step of the metabolism of all living organisms inside and outside of cells. Without proteins
Cancer is one of the major diseases in the 21st century. Hundreds of billions of dollars have been spent on cancer research in the last half century, but still, our understanding of the disease mechanisms is limited.
The force with which cells adhere to their substrate is of interest in the study of various diseases. For example, in the case of atherosclerosis, the disease that leads to heart attacks and strokes, the “leakiness” of
Articular cartilage is a tissue found in joints throughout the body (knees, elbows, etc.) that plays a significant role in allowing the body to maintain proper movement and engage in physical activities; it also supports the transfer
Supramolecular self-assembly on two-dimensional (2-D) surface is a powerful approach to construct functionalized surfaces. In a self-assembly process, molecules assemble via noncovalent interactions such as van der Waals or hydrogen bonding interactions, and form periodic nano structures.
The current “top down” strategy that aims to miniaturize silicon based electronic components will eventually reach a limit. A new approach is necessary in order to develop more powerful, less expensive and more flexible electronic devices. Molecular
