| 2 | Tweezing and manipulating micro- and nanoparticles by optical nonlinear endoscopy显示文摘The precise control and manipulation of micro-and nanoparticles using an optical endoscope are potentially important in biomedical studies,bedside diagnosis and treatment in an aquatic internal organ environment,but they have not yet been achieved.Here,for the first time,we demonstrate optical nonlinear endoscopic tweezers(ONETs)for directly controlling and manipulating aquatic micro-and nanobeads as well as gold nanorods.It is found that two-photon absorption can enhance the trapping force on fluorescent nanobeads by up to four orders of magnitude compared with dielectric nanobeads of the same size.More importantly,two-photon excitation leads to a plasmon-mediated optothermal attracting force on nanorods,which can extend far beyond the focal spot.This new phenomenon facilitates a snowball effect that allows the fast uploading of nanorods to a targeted cell followed by thermal treatment within 1 min.As two-photon absorption allows an operation wavelength at the center of the transmission window of human tissue,our work demonstrates that ONET is potentially an unprecedented tool for precisely specifying the location and dosage of drug particles and for rapidly uploading metallic nanoparticles to individual cancer cells for treatment. | Min Gu Hongchun Bao Xiaosong Gan Nicholas Stokes Jingzhi Wu | 2014 | Light(Science & Applications)2014，3，1： | 5 |
| 3 | Spin-manipulated nanoscopy for single nitrogenvacancy center localizations in nanodiamonds显示文摘Due to their exceptional optical and magnetic properties,negatively charged nitrogen-vacancy(NV−)centers in nanodiamonds(NDs)have been identified as an indispensable tool for imaging,sensing and quantum bit manipulation.The investigation of the emission behaviors of single NV−centers at the nanoscale is of paramount importance and underpins their use in applications ranging from quantum computation to super-resolution imaging.Here,we report on a spin-manipulated nanoscopy method for nanoscale resolutions of the collectively blinking NV−centers confined within the diffraction-limited region.Using wide-field localization microscopy combined with nanoscale spin manipulation and the assistance of a microwave source tuned to the optically detected magnetic resonance(ODMR)frequency,we discovered that two collectively blinking NV−centers can be resolved.Furthermore,when the collective emitters possess the same ground state spin transition frequency,the proposed method allows the resolving of each single NV−center via an external magnetic field used to split the resonant dips.In spin manipulation,the three-level blinking dynamics provide the means to resolve two NV−centers separated by distances of 23 nm.The method presented here offers a new platform for studying and imaging spin-related quantum interactions at the nanoscale with superresolution techniques. | Martina Barbiero Stefania Castelletto Xiaosong Gan Min Gu | 2017 | Light(Science & Applications)2017，6，1： | 3 |
