Minimally Invasive Delivery of Optical Nanosensors Using Injectable Hydrogels
Injectable peptide hydrogels offer a minimally invasive delivery platform for single‐walled carbon nanotube (SWCNT)‐based near‐infrared fluorescent sensors, enabling real‐time measurement of drug concentrations. Encapsulated SWCNTs show a dose‐dependent fluorescence response across physiologically relevant concentrations and retain their fluorescence ...

Fluorescence Quenching in Porous Silicon/Conjugated Polymer Composites
MEH-PPV and m-LPPP polymers were spin-coated onto porous silicon (PS). Quenching of the polymer and PS fluorescence has been investigated by means of time-resolved and steady state fluorescence spectroscopy.

Development of Nanoflare Nanosensors for Monitoring Cellular Insulin mRNA in Beta Cells and Islets
This study presents the design and application of In2‐NF probes for detecting insulin mRNA in beta cells and islets. Using spherical nucleic acid‐coated gold nanoparticles, the probes offer strong fluorescent signals upon hybridization. Their performance is validated across 2D and 3D cultures and rat islets, demonstrating sensitive, real‐time mRNA ...

Additive Manufacturing of Patient‐Specific Intracranial Aneurysm Cell Culture Models
Patient‐specific intracranial aneurysm models were fabricated using chocolate moulding, 3D printed water‐soluble cores, and direct resin 3D printing. Moulding PDMS around sacrificial cores made of chocolate or 3D printed water‐soluble resin yielded accurate, expandable, and endothelializable models that outperformed resin‐based approaches.

A fully organic UV threshold dosimeter is developed by exploiting the oxygen‐sensitive room‐temperature phosphorescence of a purely organic emitter in a polymer matrix. Upon reaching a specific cumulative UV dose, photochemical oxygen depletion triggers a sharp, high‐contrast emission.

Plasma‐induced ligand polymerization on colloidal quantum dots (QDs) renders them resistant to organic solvents, enabling conventional photoresist‐based photolithography. This approach achieves microscale patterning with feature sizes down to 3 µm, preserving the optical properties of the QDs and offering a simple and scalable route for QD‐based ...

Positional isomerism in dibenzofuran‐based n‐type hosts modulates molecular polarity, charge‐transport balance, and emissive‐layer packing. The higher‐polarity BFPDB‐2 host facilitates efficient energy funneling, reduced aggregation, and preferential dipole orientation, leading to phosphor‐sensitized fluorescence OLEDs with enhanced external quantum ...
