Graduate Research Assistant

Project: Phase intensity nanoscope opens long-time investigation windows of living matter
  • Developed a super-resolution method operating without photobleaching.
  • Using SH-SY5Y cells labeled by Gold nanorods(AuNRs) to detect the actin filament structure inside of the cell, and conducting long-term investigation to monitor cell dynamics. 
  • The use of AuNRs can allow us to reconstruct the sub-diffraction limit images by capturing images of different polarization angles. AuNR’s anti-symmetric structure yields us distinct responses on its polarization states, which can be localized to the sub-diffraction limit by the FISTA algorithm. Consequently, for the single images we can detect the actin filament structure which is approximately 8nm, and for the long-term images(cell-division movies) we can detect the cell division below 100nm scale.

Project: Soft multimaterial photonic devices for plasmonic super-resolution imaging
  • Built a small Integrated Nanoscopic Correction(mINC) device by using liquid crystal and soft material with a film polarizer and a film quarter-wave plate for super-resolution using gold nanorods
  • The phase retardation of this device can be tuned by the applied voltage to the liquid crystal and this allows us to acquire the data from different polarization states.

Project: Interferometric Phase Intensity Nanoscopy (iPINE), Revealing Nanostructural Features, Resolves Proximal Nanometer Objects below the Diffraction Limit: Implications in Long-Time Super-Resolution of Biological Dynamics
  • Built an interferometric scattering imaging system(iSCAT) with super-resolution methods using gold nanorods to detect the nanometer objects and resolve them. 
  • Used a phase intensity module composed of liquid crystal, a quarter-wave plate, and a linear polarizer to capture the data from different polarization states of gold nanorods located in below diffraction limit region. This module is controlled by Labview to apply the voltage to liquid crystal to control the phase retardation and take images at the same time.
  • Used an elliptical Airy pattern and phase intensity peak to extract each gold nanorod’s phase and applyed the FISTA algorithm to deconvolute and reconstruct the images.

Project: Optical tweezer (Current project)
  • Used a gold nanorod and optical tweezer to manipulate the cell. (Grant in review)

Researcher

Project: Extraction algorithm of light field Information from multi-focus images
  • Developed a new algorithm to extract the 4D light-field information from a few images 
  • Used the geometric transformation to extract the 4D light-field information from the images taken at different focal points
  • Data extraction without 2D Fourier transformation improves computing time, so we can deal with more data points quickly. Also, this algorithm can extract any form of point spread function, and it allows us to localize the data point into a sub-diffraction limit.

  • To measure the magnetic domain of powdered ferromagnetic material, collect a red laser(638nm) reflected from the material with different magnetization controlled by a programmable DC supply with Copper coil and measure the optical Kerr effect.
  • For the objective sample, made the Co-sputtered film, spin-coated Fe powder solution to make the Fe powder film, and analyzed the physical distribution with the Scanning Electron Microscope(SEM).

UNDERGRADUATE PROJECT EXPERIENCE

Mar 2019 – Jul 2019    Capstone design 1, Kyung Hee University, Seoul, Korea
Project: Making of nano-scale distance measuring sensors for the realization of TERS
  • The purpose of this project is to make the piezoelectric inchworms and a couple of distance measuring sensors in nano-scale required to measure the accurate movement of the tip.
  • Operated piezoelectric inchworm actuators, designed and measured sensors integrated with interferometer and graphene. Then, measured and applied the electrical characteristics change of single-layer polycrystalline graphene depending upon the strain.
  • Made interferometers and observed the interference pattern change through the charge-coupled devices, computed the movement of these conversely using MATLAB.

Project: Making of a spectrometer to measure the spectrum of a Graphene-based IR LED
  • Developed an IR spectrometer with 10 nm resolution in the spectrum range of 800~1600 nm using Arduino, step motor, diffraction grating, lenses, and IR detector.
  • Scanned the angles through a step motor to measure the intensity with the fact that a diffraction grating makes different angles of diffracted light upon each wavelength and analyzed the spectrum converting the angles back to wavelengths.
 

Sep 2018 –  Dec 2018  Optoelectronics experiment, Kyung Hee University, Seoul, Korea
Project: Making of a carbon nanotube(CNT) electron emitter for the Field Emission Display(FED)
  • Analyzed the electrical characteristic of CNT that was formed by varying the developing time and etching time which can be variables of the process. 
  • Vapor deposition of Ni, which is a catalyst for CNT growing, on the Si wafer through RF sputtering. Spin-coated the positive photoresist(PR) on the wafer, patterned with UV exposure and a mask. Developed with the developing time as the variable and obtained a board with the dot pattern PR cured. After etching Ni with the etching time as the variable and forming the Ni islands, stripped the cured PR and made the CNT through PECVD.
