Voltage-tunable polarizer
Precise polarimetric imaging of polarization-sensitive nanoparticles is essential to resolving their accurate spatial positions beyond the diffraction limit. However, conventional technologies typically employ mechanically rotated optical components, causing beam deviation errors that cannot be corrected beyond the diffraction limit. To overcome this limitation, a spatially stable nano-imaging system is presented for polarization-sensitive nanoparticles. In this disclosure, it is demonstrated that by integrating a voltage-tunable polarizer into optical microscopy, one is able to achieve high precision nano-imaging without mechanically induced image shift. It is also demonstrated that by integrating a voltage-tunable polarizer into photographic imaging system, one can achieve high-speed suppression of reflection glare and/or high-speed variation light exposure to the imager. By applying amplitude-modulated voltages, high-speed rotation of the transmission polarization and/or modulation of transmission intensity can be achieved for dynamic polarimetric nano-imaging. In addition, it is also demonstrated that by integrating a voltage-tunable polarizer into a photographic camera system, one is able to remove glare from object surfaces for providing images with more contrast, and control the variable light exposure as a variable neutral density filter. |

Methods for nuclear reprogramming using synthetic transcription factors
The current disclosure provides methods for reprogramming mammalian somatic cells by regulating the expression of endogenous cellular genes. Cellular reprogramming of somatic cells can be induced by activating the transcription of embryonic stem cell-associated genes (e.g., oct3/4) and suppressing the transcription of somatic cell-specific and/or cell death-associated genes. The endogenous transcription machinery can be modulated using synthetic transcription factors (activators and suppressors), to allow for faster, and more efficient nuclear reprogramming under conditions amenable for clinical and commercial applications. The current disclosure further provides cells obtained from such methods, along with therapeutic methods for using such cells for the treatment of diseases amendable to stem cell therapy, as well as kits for such uses. |
