In TPP, since near-infrared femtosecond pulsed laser has been used for two-photon excitation, photo-initiators are added into a resin to trigger the TPP reaction. Here, we propose a photo-initiator free TPP by utilizing monomer’s intrinsic absorption in the deep-UV (DUV) region. Chemical bonds in monomer molecules are directly two-photon-excited with a visible femtosecond pulsed laser at 400-nm wavelength. We fabricated 3D nano-structures of acrylic oligomer, inorganic materials, and biomaterials without a photo-initiator. Raman spectroscopy study clarified chemical structure changes upon DUV two-photon excitation.","PeriodicalId":117063,"journal":{"name":"Molecular and Nano Machines IV","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133416784","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}

Here we present a concise fabrication process of reusable microscope-compatible microfluidic devices for biophotonic applications. The method requires commonly available components, such as a 3D printer or 3D pen, heat plate, sonicator, PDMS, and acetone. For high NA objective’s measurements, a cover glass can be inserted and replaced from the main microfluidic chamber. For our studies of the controlled bacterial biofilm formation, a laser beam is also delivered from the side of the microfluidic device with a fiber-coupled laser or from the bottom through an objective.","PeriodicalId":117063,"journal":{"name":"Molecular and Nano Machines IV","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124930078","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 report a novel fuel-free propulsion mechanism induced by an external light stimulus. The actuation relies on refraction of light, while the net propulsion force emerges from an asymmetric particle shape and a symmetry-broken refractive index profile. Two-photon polymerization is employed for fabrication of the artificial machines, whose geometries and refractive index profiles are optimized with the help of numerical simulations. We demonstrate the directional movement of refractive light-propelled particles, and the increased performance of artificial refractive index machines.","PeriodicalId":117063,"journal":{"name":"Molecular and Nano Machines IV","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127193075","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 microdroplet can be easily trapped to form a single plasmonic nanocore on a receiver substrate with a spatial resolution beyond the diffraction limit. Going beyond conventional fabrication processes for plasmonic structures, such as lithography technologies based on electron and ion beams, such plasmonic nanocore formation in a water microdroplet should offer us new fabrication technology for plasmonic structures.","PeriodicalId":117063,"journal":{"name":"Molecular and Nano Machines IV","volume":"17 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133390450","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}
