Early screening of plants for pathogenic infections can serve as a boon in the Agricultural sector. The standard microbiology techniques have not kept pace with the rapid enumeration and automated methods for bacteria detection. Electrochemical impedance spectroscopy (EIS) serves as a label free bio sensing technique to monitor pathogens in real time. The changes in the electrical impedance of a growing bacterial culture can be monitored to detect activity of microorganisms. In this study, we demonstrate development of a gold interdigitated electrode (gold IDE) based impedance biosensor to detect bacterial cell enrichment in a growth medium. To standardize the impedance measurement protocol, nutrient broth suspended E.coli cells were used as a model system. The changes in the magnitude of impedance is about 1.5MΩ per doubling of E.coli cells. We further extended this strategy to identify the pathogens in real samples using milk as cell growth medium. Distinct difference of about 5MΩ was seen in the impedance recorded for the healthy and infected potato samples. Our results support the potential application of this impedance based biosensor in agricultural pathogen detection","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"34 1","pages":"385-388"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80062211","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}

Despite its favorable properties, graphene has not fully transitioned as a mainstream electronic material due to challenges involved in its patterning and integration to standard device fabrication process flows. In this study, an elastomeric stamp-assisted exfoliation and transfer approach has been developed, where patterned graphene layers were seamlessly transferred by contact with a polydimethylsiloxane (PDMS) stamp with an applied weight of ~ 30 grams or less. With the approach presented herein, lengthy wet etching cycles to remove the underlying nickel or copper precursors during CVD-growth of graphene have been eliminated. Results indicate that the proposed technique is capable of direct, etch-free transfer of various graphene patterns up to ~ 50 µm in size and with high yield. Optical microscopy, SEM imaging, atomic force microscopy (AFM), and Raman spectroscopy characterization of transferred layers demonstrate retainment of the pristine graphene quality after the elastomeric stamp-assisted exfoliation and transfer process with no contamination or damage on the transferred graphene patterns.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"48 1","pages":"64-67"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89206138","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}

These dots have potential to replace the use of traditional semiconductor quantum dots in white light emitting devices. For successful application of these dots in White LEDs it is highly essential to synthesize luminescent CDs and CDphosphor with higher Quantum yields (QY). Immense research is going on across the globe in enhancing the optical properties of CDs and CD phosphor by proper surface functionalization and passivation of CD surface. In this paper we report successful fabrication of single system white light emitting CDs, CD phosphor and two different schemes to enhance the Quantum yield of fabricated CDs and CD phosphor by modifying the CD surface. The so fabricated CDs and CD phosphor emit white light under UV -illumination. Further the fabricated CDs and CD phosphor are characterized using UV-absorption emission spectroscopies and the quality of white light obtained from CDs and CD phosphor is characterized using CIE chromatic co-ordinates.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"28 1","pages":"356-359"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76176292","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}

RC system extracts features from input by projecting them into a high dimensional space. A major advantage of RC framework is that it only requires the readout layer to be trained which significantly reduces the training cost for complex temporal data. In recent years, memristors have become extremely popular in neuromorphic applications due to their attractive analogy to biological synapses. Alamethicin-doped, synthetic biomembrane can emulate key synaptic functions due to its volatile memristive property which can enable learning and computation. In contrast to its solid-state counterparts, this two-terminal biomolecular memristor features similar structure, switching mechanism, and ionic transport modality as biological synapses while consuming considerably lower power. In this work, we have shown biomolecular memristor-based reservoir system to solve tasks such as classification and time-series analysis in a simulation based environment. Our work may pave the way towards highly energy efficient and biocompatible memristor-based reservoir computing systems capable of handling complex temporal tasks in hardware in the near future.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"22 1","pages":"116-119"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73704905","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}

Trans-polyacetylene is a conducting polymer having n repetitive units of $(-mathrm{C}=mathrm{C}-)_{n}$, indicating inherent conjugation in nature. In the present work, a two-probe model of pristine and defects (hybridization and torsion) induced trans-polyacetylene with the semi-infinite zigzag graphene nanoribbon (ZGNR) electrodes have been modeled and employed to analyze the transport properties, within the framework of Density Functional Theory (DFT) and Non-Equilibrium Green's Function (NEGF) formalisms. We report that the incorporation of hybridization and torsion defects decreases the drive current. Moreover, the hybridization defect has caused about 75 times reduction in the drive current at 2V, whereas both hybridization and torsion defects shows a reduction by about 21 times with respect to the pristine model. The computed transmission spectrum, transmission pathways, and molecular projected self-consistent Hamiltonian (MPSH) eigenstates, very well comprehend the degradation of drive current in the altered models.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"46 1","pages":"185-188"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88318874","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}
