Since these processes occur in all n atural\, artificial or conceptual situations involving two surfaces (at le ast) in contact or in close proximity to each other\, it is not surprising that\, knowingly or not\, many physicists\, materials scientists\, mechan ical engineers or chemists must sooner or later confront these topics in t heir careers. In this talk\, I will first present investigations on the fr iction force acting on single molecules [1]\, polymer chains [2] or metal clusters [3] manipulated on solid surfaces an AFM probe. If the surface it self is “manipulated”\, it becomes possible to observe and quantify ea rly stages of abrasive wear on the nanoscale\, which is of utmost importan ce for assessing the quality of technical surfaces and possible environmen tal issues. Particularly instructive in this content are the cases of comp liant polymers [4\,5] and layered materials[6\,7]\, where ripples\, round- shaped nanoparticles\, and flakes are easily generated out of the nanoscra tch processes. Finally\, I will also introduce first results on sliding fr iction in liquid environments and the influence of nanoroughness on latera l force sensing that we are currently studying in collaboration with TU Dr esden.\n\n[1] R.

Indeed\, nanomaterials such as carbon black\, gold nano particles\, and graphene\, have proved their potential to enhance the sens itivity of such analytical tools\, providing a large surface area for bior eceptor immobilization as well as higher electron transfer and thus improv ed opto-electrochemical signals (4\,5). \nIn addition\, different artifici al molecules such as aptamers\, peptidomimetics\, molecular imprinting pol ymers (MIPs)\, and peptide nucleic acids (PNAs)\, can be nowadays designed and synthesized with tailored features of stability and affinity towards a specific target (6\,7). Moreover\, many innovative materials\ncan be exp loited for biosensor configuration\, including paper as a sustainable and smart substrate for bioreceptor immobilization\, microfluidic design\, and sample treatment (8). Finally\, pioneering strategies for bioreceptor imm obilization demonstrated to improve standardization and repeatability\nin the realization of biosensors (9). In this scenario\, the last trends on b iosensors developed for environmental and biomedical applications are pres ented with recent examples of biosensing setup.\n\n1.

Moreover\, a special att ention has to be paid to the eventual damage induced by the electron irrad iation that can alter the structure of the specimen. Radiation damage has a dramatic sudden effect on soft matter or biologic specimens but can also affect in a subtle way the study of inorganic specimens\, preventing an a ccurate and reliable quantification of their properties. The use of new TE M/STEM aberration corrected equipment and field emission cathodes enable t o deliver a high-density of current on the specimen making radiation damag e an issue of growing importance also for inorganic material and even for metals. Radiation damage is the basic handicap to atomic resolution of sin gle particle in biology or to the development of atomic resolution methods for electron tomography. Here is discussed how in-line holography in Tran smission Electron Microscopy enables the study of radiation-sensitive nano particles of organic and inorganic materials providing high-contrast holog rams of single nanoparticles\, while illuminating specimens with a density of current as low as 1 e-Å-2s s-1. This provides a powerful method for t rue single-particle atomic resolution imaging and opens new perspectives f or the study of soft matter in biology and materials science(1). The appro ach is not limited to a particular class of TEM specimens\, such as homoge nous samples or samples specially designed for a particular TEM experiment but has better application in the study of those specimens with differenc es in shape\, chemical composition\, crystallography\, and orientation\, w hich cannot be currently addressed at atomic resolution.\n\n1 Elvio Carlin o\, In-Line Holography in Transmission Electron Microscopy for the Atomic Resolution Imaging of Single Particle of Radiation-Sensitive Matter.
