SenExo-cCCT2 Reprograms Senescence Response and Anti-Tumor Immunity Following FOLFIRINOX Chemotherapy in Pancreatic Ductal Adenocarcinoma. [PDF]
Adv Sci (Weinh)This study demonstrates that SenExo‐cCCT2 enables targeted delivery of cCCT2 to pancreatic cancer cells, where it disrupts IPO13‐mediated nuclear translocation of UBC9, impairing SUMOylation‐dependent DNA damage repair and inducing senescence. Senescent tumor cells secrete CXCL10 to recruit CD8⁺ T‐cells while upregulating PD‐L1.

From vertical-cavities to hybrid metal/photonic-crystal nanocavities: towards high-efficiency nanolasers [PDF]
, 2012 We provide a numerical study showing that a bottom reflector is indispensable to achieve unidirectional emission from a photonic-crystal (PhC) nanolaser.

Plasmonic crystal defect nanolaser
Optics Express, 2011 Surface plasmons are widely interesting due to their ability to probe nanoscale dimensions. To create coherent plasmons, we demonstrate a nanolaser based on a plasmonic bandgap defect state inside a surface plasmonic crystal. A one-dimensional semiconductor-based plasmonic crystal is engineered to have stopbands in which surface plasmons are prohibited

Plasmonic Bowtie Nanolaser Arrays [PDF]
Nano Letters, 2012 Plasmonic lasers exploit strong electromagnetic field confinement at dimensions well below the diffraction limit. However, lasing from an electromagnetic hot spot supported by discrete, coupled metal nanoparticles (NPs) has not been explicitly demonstrated to date. We present a new design for a room-temperature nanolaser based on three-dimensional (3D)

“Amplified Spontaneous Emission” in Micro- and Nanolasers
Atoms, 2021 Amplified Spontaneous Emission is ubiquitous in systems with optical gain and is responsible for many opportunities and shortcomings. Its role in the progression from the simplest form of thermal radiation (single emitter spontaneous emission) all the ...

IEEE Photonics Journal, 2012 Recent progress in the field of semiconductor nanolasers is discussed. New designs have emerged that eliminate the need for a conventional Fabry–Perot cavity, bringing down the physical dimensions of the lasers below the diffraction limit. Semiconductor nanolasers are critical components for nanophotonics and offer possible integration with Si ...

Lasing from a circular Bragg nanocavity with an ultra-small modal volume [PDF]
, 2005 We demonstrate single-mode lasing at telecommunication wavelengths from a circular nanocavity employing a radial Bragg reflector. Ultra-small modal volume and Sub milliwatt pump threshold level are observed for lasers with InGaAsP quantum well active ...
