The photo electric characteristics of the developed photo sensor has been analysed in terms of photo current, photo responsivity and quantum efficiency in 300nm – 900nm wavelength region. These all parameters have been improved considerably by incorporating Si/4H-SiC multi layers structure into the active region of the devices. Recently demand of such bio-medical photo-sensors is increasing significantly for identification of anti-bodies and virus in human blood. The validity of newly developed model has been established by comparing the simulated result with the reported experimental data. The photo electrical characteristics analysis of the designed QMC model-based Si/4H-SiC multi layers avalanche photo sensor depict that the photo current is ~20μA whereas the photo responsivity and quantum efficiency are ~0.65A/Wand ~0.67 respectively. The results clearly establish the superiority of proposed photo-sensor for developing medical instruments in visible wavelength region (300nm – 900nm).","PeriodicalId":134550,"journal":{"name":"EngRN: Photonics (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125132994","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}

We evaluated the phototheranostic nanoparticle-related properties of liposomally formulated phospholipid-conjugated indocyanine green, denoted as LP-iDOPE, for cancer diagnosis and treatment using photobiomodulation with a near-infrared (NIR)-light emitting diode (LED) light irradiator. Using in vivo NIR fluorescence imaging, we demonstrated that LP-iDOPE was selectively delivered to tumor sites with high accumulation and a long half-life. Following NIR-LED light irradiation of the tumor region of LP-iDOPE accumulation, effector CD8+ T cells were activated at the secondary lymphoid organs, migrated, and subsequently released cytokines including interferon-γ and tumor necrosis factor-α, resulting in effective tumor regression. Our cancer immunotherapy strategy using LP-iDOPE as a phototheranostic nanoparticle and an NIR-LED light irradiator as a photobiomodulation device represents a promising approach to noninvasive cancer therapy.","PeriodicalId":134550,"journal":{"name":"EngRN: Photonics (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129745245","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}

English Abstract: Molybdenum Disulfide, MoS2, layers among two dimensional atomic family structures shows potential use for application in photovoltaic devices. However, their absorption intensity and wavelength range need improvement. In this paper, to increase the absorption intensity with flat top absorption profile, the MoS2 monolayer is inserted in S4 Fibonacci quasi photonic crystal together with other dielectric layers, e.g. Si and SiO2. We found that the S4 thickness will differ for designing of the structure based on either of resonance peaks of MoS2 monolayer. Based on three resonance peaks of MoS2, three structures designed for S4 and their absorption for normal incidence based on transfer matrix method are calculated. Finally, S4 Fibonacci structure with 609 nm of designed wavelength and 12 times periodicity demonstrates giant absorption above 90% with flat top profile between 605 and 665 nm as the best achievement.","PeriodicalId":134550,"journal":{"name":"EngRN: Photonics (Topic)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128685447","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 paper, to simultaneous application of photonics crystals and MoS2, periodic photonic crystal structures including Si, SiO2 and MoS2 are demonstrated.
