In this paper, we analyze and investigate the molecular communication network consisting of single transmitter and receiver biological nanomachines with the same type of carrier molecule. This communication takes place over a single-relay link that is used the sense-and-release technique assisting our communication channel, in which intermediate relay do not attempt to decode the information. This paper considers that the cooperative relay technology, which fits to peer-to-peer transmission, can significantly benefit the combination between the cooperative diversity and the controlled-release-time in such a network. Furthermore, the inter-symbol interference (ISI) problem and reception noise are considered. The results illustrate that the sense-and-controlled-release-time (SCRT) scheme is the powerful technique in improving the BER performance up to 5dB SNR gain compared to the State-of-the-Art relaying schemes. As a result, this scheme can be substantially reduced the complexity of the receiver’s threshold-based detection strategy. Finally, experimental results show that the MC throughput of the entire network is greatly increased by exploiting the benefit of the cooperative relay with SCRT scheme.","PeriodicalId":398305,"journal":{"name":"2018 IEEE 12th International Conference on Nano/Molecular Medicine and Engineering (NANOMED)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128358884","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}

Recently, copper based NCs have garnered immense attention due to their intriguing optical properties, which show great promise in the biomedical arena. Firstly, CBS NCs present a solid absorption in the NIR region. Secondly, polymer hybrid conjugated CBS NCs can themselves serve as therapeutic agents due to the photo/light triggered hyperthermia and/or ROS generation ability. We show that upon NIR irradiation of intravenously CBS administered tumors, photodynamic therapy was instigated at irradiated site, selectively ablating the tumors by absorbing externally applied ultra-low power (10 mW/cm2) NIR light. With their X-ray contrast imaging potential and photodynamic therapeutic effects, we are confident that these CBS NCs will be helpful to image/monitor and simultaneously treat various ailments including from cancer.","PeriodicalId":398305,"journal":{"name":"2018 IEEE 12th International Conference on Nano/Molecular Medicine and Engineering (NANOMED)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116604163","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}

In this work, metronidazole, an antibacterial agent, was loaded in niosomes and coated on dental implants using layer-by-layer dip coating technique with poly(lactic acid) (PLA). Drug loaded niosomes was fabricated via thin film hydration method. The niosomes was coated by varying the dipping cycle. The dental implants were coated for 90 cycles and were characterized further to determine drug loading content, release profile and inhibition zone. In detail, average drug loading content was 22.85 ± 1.56 μg. Antibacterial study showed that Metronidazole release could inhibit bacteria. Therefore, the result suggested that the layer-by-layer dip coating on dental implants for antibacterial application could be potentially elevated by using niosomes.","PeriodicalId":398305,"journal":{"name":"2018 IEEE 12th International Conference on Nano/Molecular Medicine and Engineering (NANOMED)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133906029","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}

As advanced results, the collected PM2.5 was successfully detected and analyzed via ion current sensing using a micropore.
