Real-time control of micro/nanofiber waist diameter with ultrahigh accuracy and precision

Yingxin Xu, Limin Tong et 2 al.

Apr 26, 2017 in Optics Express
We demonstrated real-time control of micro/nanofiber waist diameter during fiber pulling process with ultrahigh accuracy and precision. A 785 nm CW laser was coupled into SMF-28e fiber to excite high-order modes. During the fiber-pulling process, the cutoffs of high-order modes contributed to sudden transmission intensity drops. By accurately measuring the time interval between two drops, we could...

Oral Health Self-Management Ability and Its Influencing Factors among Adolescents with Fixed Orthodontics in China: A Mixed Methods Study.

Yan Li, Li Li et 4 al.

Aug 27, 2022 in Disease markers
To understand the oral health self-management ability status and influencing factors among adolescent patients with fixed orthodontics in Nanjing and to provide a reference for formulating targeted intervention measures. A mixed research method was used. First, the convenience sampling method was used to select adolescent patients with fixed orthodontics admitted to the orthodontic department of a...

Multifunctional ZnO@CuS nanoparticles cluster synergize chemotherapy and photothermal therapy for tumor metastasis.

Huizi Deng, Qi Shen et 7 al.

Apr 14, 2021 in Nanomedicine : nanotechnology, biology, and medicine
The poor drug delivery and unsatisfying therapeutic effects remain to be the primary challenges for cancer therapy. Nanosystem that combines multiple functions into a single platform is an ideal strategy. Here, a smart drug delivery nanoplatform (Z@C-D/P) based on ZnO@CuS nanoparticles, loaded with doxorubicin (DOX) and pirfenidone (PFD) was constructed. Importantly, the β-CD-DMA and PEG-DMA could...

Fabrication of three-dimensional microdisk resonators in calcium fluoride by femtosecond laser micromachining

Jintian Lin, Ya Cheng et 7 al.

Jan 13, 2014 in Arxiv
We report on fabrication of on-chip calcium fluoride (CaF2) microdisk resonators using water-assisted femtosecond laser micromachining. Focused ion beam (FIB) milling is used to create ultra-smooth sidewalls. The quality (Q)-factors of the fabricated microresonators are measured to be 4.2x10^4 at wavelengths near 1550 nm. The Q factor is mainly limited by the scattering from the bottom surface of ...

Low-threshold whispering-gallery-mode microlasers fabricated in a Nd: glass substrate by three-dimensional femtosecond laser micromachining

Jintian Lin, Ya Cheng et 8 al.

Mar 4, 2013 in Arxiv
We report on fabrication of whispering-gallery-mode microlasers in a Nd:glass chip by femtosecond laser three-dimensional (3D) micromachining. Main fabrication procedures include the fabrication of freestanding microdisks supported by thin pillars by femtosecond laser ablation of the glass substrate immersed in water, followed by CO2 laser annealing for surface smoothing. Lasing is observed at a p...


A novel method to immobilize collagen on polypropylene film as substrate for hepatocyte culture

Yong Zhang, Yingxin Xu et 4 al.

Jan 1, 2006 in Materials Science and Engineering: C
To improve the biocompatibility of polypropylene membrane with hepatocytes, film was firstly allowed to generate peroxide groups by ammonium peroxydisulfate (APS) thermal decomposition and was then carboxylated by free radical grafting polymerization using acrylic acid as the monomer and ferrous(II) ions as redox initiator. Collagen was then covalently immobilized through amide bonds between the r...

Ultrahigh-Precision Diameter Control of Nanofiber Using Direct Mode Cutoff Feedback

Yi Kang, Limin Tong et 6 al.

Jan 1, 2020 in IEEE Photonics Technology Letters
Precise diameter control is critical for many optical micro/nanofiber (MNF) applications. We demonstrate real-time MNF diameter control with improved accuracy and precision. Different from earlier works, a white light source is applied to monitor the transmittance during fiber pulling process. Terminated directly by the transmission intensity drops that indicate the cutoff of TE01 mode at particul...
