Rigid polymer matrix enables direct red afterglow from rhodamine dyes without energy transfer

FlexMat, EarlyView.
This work presents a universal and facile strategy to achieve direct red room‐temperature phosphorescence from commercial rhodamine dyes by harnessing the superior rigid confinement of a novel phosphorus‐containing polymer (DOBP), effectively bypassing the complex TS‐FRET process.

Viability of Tumor Cells in Bone Dust: Implications for Oncologic Skull Base Surgery

Head &Neck, EarlyView.
ABSTRACT Background Head and neck tumors with skull base involvement may require drilling of tumor infiltrated bone. We hypothesize that bone dust generated during this process contains viable tumor cells that may seed the surgical field. Methods Tumors with gross bone invasion were drilled, and dust was collected for H&E, cell viability analysis, and ...

Confocal Ex Vivo Margin Assessment in Transoral Laser Cordectomy: A Pilot Diagnostic Accuracy Study

The Laryngoscope, EarlyView.
ABSTRACT Objectives Margin assessment in transoral laser microsurgery (TLM) for glottic squamous cell carcinoma is challenging due to specimen size, fragmentation, and artifacts. This study evaluated the feasibility and preliminary diagnostic performance of the Histolog Scanner, an ultra‐fast ex vivo confocal microscopy system, for intraoperative ...

Designing Thermally Stable DNA Hydrogels via Entropically‐Driven Acridine Intercalation

Macromolecular Rapid Communications, EarlyView.
Environmental variables are shown to systematically tune the network dynamics of entropy‐driven, acridine‐based DNA‐intercalating supramolecular hydrogels. Adjusting the buffer composition, ionic identity, and salt concentration impacts electrostatic screening and counterion release of the DNA backbone, offering a powerful handle to tune elasticity and

The Partner Does Matter: The Structure of Heteroaggregates of Acridine Orange in Water

Molecules, 2019
Self-assembly of organic molecules in aqueous solutions is governed by a delicate entropy/enthalpy balance. Even small changes in their intermolecular interactions can cause critical changes in the structure of the aggregates and their spectral ...
