“…Hence, the properties of nanoscaled coatings are affected, as well as adhesion and roughness (83). Hence, the formation of film-forming species (plasma-chemical reaction pathway) is not altered.…”

“…Using a plasma-enhanced chemical vapour deposition (PECVD) process, the mechanical and usually also the optical properties of the native polymer materials remain unaltered. Though, by varying the plasma parameters during PECVD, coatings with many different functionalities like barrier, protective or anti-adhesive coatings can be prepared without causing negative effects on the basic packaging functions [36][37][38]. In this study the focus is on functional layers on a nanometer scale prepared by PECVD.…”

Liquid food products stick to solid surfaces. This problem occurs in all supply chain steps from production to recycling. Although the basic problem has been known for a long time, the parameters influencing the interfacial adhesion have not been clarified yet. Here, two methods (product depletion test and tack test) to evaluate the adhesion of highly viscous liquids to solid surfaces have been developed. The product depletion test allows the assessment of the residue amounts and covered surface areas during the gravity-driven flow on an inclined plane. The tack test is conducted by filling the gap between two parallelly mounted, horizontally oriented plates with a liquid product and measuring the normal force while separating the plates by pulling off the upper plate under defined conditions. The influence of the experimental parameters on the maximum normal force (F max ) could be shown. While the correlation between the pull off velocity of the upper plate and F max follows a power law, the dependency between the gap size and F max follows an exponential function. Although no significant correlation between F max or the work of adhesion (W a ) and the solid's properties could be identified, a correlation between F max and W a was observed. As shown by product depletion with ketchup, although the surface coverage is only slightly influenced by the packaging material, the opposite is the case for the covered surface area which, therefore, determines the residue amounts. For some coated samples a large residue reduction was observed.

Summary: Several actual developments in medical therapy are focussing on the potential of a surface‐dependent selection and proliferation of special cell types. For an improvement of biocompatibility it is interesting to understand the interactions between cells and material surfaces in order to create devices with the respective characteristics. In this paper the possibility to isolate three different tumor cells lines are studied: HEK293, RINm5f and KYM‐1. A procedure by means of plasma polymerization is demonstrated to create hydrophilic microstructures (precursor: AAc) on a hydrophobic (precursor: CHF3) substrate and shown to effectively select RINm5f cells. Moreover, by studying the interaction between culture media and deposited polymers, it is shown that Ca2+ ions and protein adsorption play a fundamental role in the cell‐substrate adhesion and proliferation.
