“…Due to its bioactivity and biodegradability Ch is popular among pharmaceutical, medical and cosmetic concerns. It is used primarily as a support for the supply of drugs and proteins (Moradi et al 2019), biosensors (Zhang et al 2018), nanofibers (scaffolds in tissue engineering) (Rijal et al 2018;Bhowmick et al 2018). In the area of life science, titanium dioxide (TiO 2 ) is also often found, which is generally associated with its role as natural, physical UV filter or drug filler.…”

The studies of model biological membranes consisted of phospholipid 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) were carried out by means of the Langmuir monolayer technique using subphases containing chitosan (Ch), titanium (IV) oxide (TiO 2 ), hyaluronic acid (HA) or mixture of them. The aim was to determine the effect of individual components of subphase and their respective combinations on behavior of the DPPC membrane. The systems were tested at room temperature (20 °C) and at a natural pH of about 4.8, which was close to the pH of the human skin (4.7-5.6). The surface pressure-area per molecule (π-A) isotherms were obtained. Their analysis showed that all substances studied affected the phospholipid membrane which was revealed in the changes of mean molecular area, compression modulus and pressure of the liquidexpanded/liquid-condensed (LE/LC) phase transition. The results were discussed in terms of the nature and strength of mutual interactions. The more profound effect was found at low surface pressures at which the monolayers occurred in more expanded state. However, at the surface pressure corresponding to that of biological membranes, systems had very similar parameters compared to model DPPC isotherm.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Composite materials with carbon nanotube and graphene attachments have been regarded as promising prospects. Carbon nanocomposites have gained considerable interest in different fields including biomedical applications due to its exceptional structural dimensions and outstanding mechanical, electrical, thermal, optical, and chemical characteristics. The significant advances made in carbon nanocomposite over past years along with the discovery of new nanocomposite processing technologies to improvise the functional impact of nanotube and graphene composites by providing proper methods of synthesis and improving the production of diverse composite based on carbon nanomaterials are discussed. Carbon nanocomposites are applied in various fields such as aviation, batteries, chemical industry, fuel cell, optics, power generation, space, solar hydrogen, sensors, and thermoelectric devices. The recent design, fabrication, characteristics, and applications of carbon nanocomposites such as active carbon, carbon black, graphene, nanodiamonds, and carbon nanotubes are explained in detail in this research. It is found that unlike traditional fiber composites, Van der Waals force interfacial compounds have an important effect on the mechanical performance of carbon nanomaterial-based composites.

“…Leptin, another biomarker, has also had a variety of sensors developed for it, though typically these sensors are initially for diagnosing obesity risk, they none-the-less could be applied to uterine cancer diagnosis. These sensors include electrochemical sensors, [224][225][226][227][228] chemiluminescence, 229,230 and SPR. 231 This wide variety sensors and methods may allow us to bring leptin quantification into diagnosis of uterine cancers.…”
