The simplest case considered uses a vertically-oriented electric dipole radiator that is located a distance above a surface being displaced by ultrasound. The relatively high symmetry of this model geometry permits analytical representation of the fields radiated by the dipole including those associated with interactions with the material surface. The amplitude and the phase of the directly-reflected and the lateral wave fields depend on the material properties and on the distance of the dipole above the surface. When combined with the direct field, these fields coherently interfere to produce a radiation pattern above the surface that includes information about surface displacements associated with ultrasonic arrivals. In particular, the optical power radiated into the far-field can be monitored and used for ultrasound detection. Expressions for the radiated power are developed that include the dependence on material properties and explicitly show the contributions of the directly-reflected and lateral wavefields. These expressions are particularly simple when the material has limiting values of either electrical conductivity or dielectric permittivity, but the focus of the current work is on materials that cannot be described by these extreme property limits. Consideration of the general case permits a broader exploration of the ultrasonic signals that would be produced in these types of systems. This work examines the sensitivity of near-field probes to ultrasonic displacements and provides guidance on approaches to optimization of ultrasound detection using these types of probes.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"31 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80962063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, there are over 500 copper alloys registered with the EPA for their proven antipathogenic capabilities. These materials are unique compared to traditional disinfectants because of their broadband activity, longevity and ability to self-sterilize. They have significant potential in healthcare, industrial, and commercial settings because they are non-specific and able to kill all pathogens tested thus far. However, in the past they have been hindered by their action timeline; conventionally available bulk coppers are highly oxidized and frequently have very low surface areas. We have developed a novel copper configuration that remains unoxidized and possesses an extremely high surface area, thus making it ultra-active against pathogens. The testing we have done makes a very promising case for our copper, ActiveCopper, to be used in settings that experience frequent contact and need to be disinfected frequently. It eliminates infectious agents in less than a minute and retains that ability for years. In this paper we explore the possible mechanisms behind its unprecedented action and exhibit our analyses of its characteristics.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"39 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73121119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current research strategies also involve revealing of the relationship between protein structure and function due to the exposure and interaction of proteins with non-biological organic and inorganic solid surfaces. Aiming at understanding of the mechanisms of protein adsorption on solid surfaces we follow in this work the organization dynamics of proteins (Bovine Serum Albumin, BSA and Fibronectin, Fn) adsorbed on thin silica layers without or with silver nanoparticles (AgNPs), deposited on their surfaces. It is found that although starting with the same protein concentration in solution (0.05 g/L), the adsorbed amount of proteins on SiO2 surfaces is twice larger for Fn $(1.32 mu mathrm{g}/text{cm}^{2})$ compared to BSA $(0.58 mu mathrm{g}/text{cm}^{2})$. The proteins adopt different conformations according to the surface pattern. On a flat SiO2 surface, the BSA proteins organize in a lace-like network while the Fn proteins adopt a branching-type. The patterned by AgNPs surfaces induce conformational changes of the proteins. In interaction with AgNPs both types of proteins fold up to attain mainly compact globular conformation.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"40 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76680014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
