AB  - Nanomembranes, freestanding quasi-2D structures with thickness of the order of tens of nm and smaller and a giant aspect ratio with lateral dimensions of the order of millimeters, even centimeters, represent an important building blocks in micro and nanosystems [1], corresponding to ubiquitous bilipid membranes in living cells [2]. In this contribution we present our results in theory, design and experimental fabrication of metallic and metal-dielectric nanomembranes with plasmonic properties, intended for the use in the field of sensing. We first consider different approaches to functionalization and nanostructuring of nanomembranes [3]. These include introduction of noble metal or transparent conductive oxides fillers directly into the nanomembrane, lamination (multilayering) and patterning by 2D arrays of subwavelength nanoholes. Within this context we describe our results on nanofabrication of 8 nm thick chromium-based composite nanomembranes. Biomimetic structures utilizing nanochannel-based pores are also considered. We further present our results related to the design of chemical and biological sensors based on nanomembranes with plasmonic metamaterial properties [4]. Such sensors function as refractometric devices utilizing evanescent near fields as optical concentrators and adsorption-desorption mechanism, which ensures their ultra-high sensitivity that reaches single molecule detection [5]. We present some results on chemical sensors utilizing nanomembranes exhibiting extraordinary optical transmission, as well as those based on doublefishnet structures. Finally we consider the enhancement of infrared detectors by nanomembranes [6] utilizing the designer plasmon mechanism [7].

AB  - Data tracking and hacking is especially dangerous in modern defence forces where classified data transmission must envolve cryptographic methods for secure and reliable data coding. The more unpredictable the cipher is, the more reliable is the message. Hardware random number generator or true random number generator (TRNG) is crucial part for every telecommunication system that involves secure and confidential electronic data transfer (official state agencies, e-banking, military data networks…) because it generates random numbers from a physical process which provides statistically random noise signals, which are trully unpredictable contrary to pseudo-random number generators generated by various software algorithms. A typical hardware random noise generators employs transducer to convert random physical process (thermal noise, photoelectric effect or other quantum phenomena) to electrical signal, amplifiers and AD convertors. On the other hand, pseudo-random number generation based on methods and algorithms may be examined by statistical tests for randomnes and proove if it is cryptographically secure. We analyze the possibility to implement adsorption-based sensors noise for the creation of allgorithm for pseudo-random number generaton and also the possibility of adsorption-based hardware random generator.
