Ultrafast light-sheet optical tweezers for in situ parallelized biomechanical characterization of cells and soft tissues
Krishangi Krishna, Gannon Lemaster, Jieyi Xu +8
Quantitative characterization of the mechanical properties of cells and tissues is essential for understanding disease progression and tissue regeneration. Optical tweezers (OT) en…
Selective Tweezing and Immobilization of Colloids for Dexterous Manipulation of Biological Materials
Krishangi Krishna, Jieliyue Sun, Zhaowei Jiang +3
The assembly of arbitrary 3D structures using nano- to micron-scale colloidal building blocks has broad applications in photonics, electronics, and biology. Combining optical tweez…
Harnessing ultrafast optical pulses for 3D microfabrication by selective tweezing and immobilization of colloidal particles in an integrated system
Krishangi Krishna, Jieliyue Sun, Wenyu Liu +2
Microfabrication using nano- to micron-sized building blocks holds great potential for applications in next-generation electronics, optoelectronics, and advanced materials. However…
Femtosecond laser-assisted selective holding with ultra-low power for direct manipulation of biological specimens
Krishangi Krishna, Joshua A. Burrow, Zhaowei Jiang +3
Traditional optical tweezers techniques often rely on high-power continuous wave (CW) lasers, which can introduce unwanted thermal effects and photodamage to delicate samples. To o…
Realization of high-dynamic-range broadband magnetic-field sensing with ensemble nitrogen-vacancy centers in diamond
Cao Wang, Qihui Liu, Yuqiang Hu +9
We present a new magnetometry method integrating an ensemble of nitrogen-vacancy (NV) centers in a single-crystal diamond with an extended dynamic range for monitoring the fast cha…
Excitation of Surface Plasmon Polaritons by Diffraction-Free and Vector Beams
Mbaye Diouf, Joshua A. Burrow, Krishangi Krishna +3
Surface plasmon polaritons (SPPs) are traditionally excited by plane waves within the Rayleigh range of a focused transverse magnetic (TM) Gaussian beam. Here, we investigate and c…
