Types of ultraviolet filters and their combination used in sunscreen determine the appropriate sun protection factor values in vivo

Journal of the Egyptian Women’s Dermatologic Society
Background The application of sunscreen has been shown to prevent the detrimental effects of ultraviolet. The effectiveness of a sunscreen formulation protection against ultraviolet B is measured by sun protection factor (SPF) and its value determined by

Polyfluoroalkyl‐Tagged Cell‐Penetrating Peptide‐Additives Enhance Intracellular Protein Delivery via Sustained Monomeric Lipid Interaction

Angewandte Chemie International Edition, Volume 65, Issue 23, 1 June 2026.
We introduce cell‐penetrating peptides (CPPs) with polyfluoroalkyl‐tags that drastically enhance intracellular protein delivery by promoting membrane retention. Via the combination of live‐cell imaging, biophysical analysis, and computational simulations, we reveal how fluorous CPPs interact with membranes via monomeric interactions and dynamic tag ...

Pharmaceutical Compounds as Photostabilizers

Journal of Al-Nahrain University-Science, 2016
n this paper, some pharmaceutical compounds were used and their impact on the photostability of polymer poly (vinyl chloride) (PVC) was study. The PVC films containing a variant concentration of compounds 0.25, 0.5, 1% by weight were produced by casting method from tetrahydrofuran (THF) solvent. The photostabilization activities of these compounds were

DNA‐Based Exciton Collider to Monitor Exciton Diffusion and Annihilation

Small Structures, Volume 7, Issue 4, April 2026.
We used DNA origami to build one‐dimensional photonic wires with up to nine precisely positioned organic dyes. Excitons are injected from both ends via FRET and diffuse along the wire; their encounters trigger singlet‐singlet annihilation, leading to single‐photon emission.

Applications of functional dyes in biomedicine and life sciences [PDF]

, 2020
Functional dyes are useful tool in Biomedical and Life Sciences. In chapter 2 and 3, we introduced a general and simple design concept using unnatural amino acids (UAAs) as flexible scaffold to link organic fluorophore covalently to a photostabilizer on ...

Impact of Docking Strand Design on Spatial Resolution in DNA‐Points Accumulation for Imaging in Nanoscale Topography

ChemPhysChem, Volume 27, Issue 5, 13 March 2026.
The design of DNA‐PAINT docking strands critically influences spatial resolution and signal stability. By comparing single (1 × R1) and repetitive (5 × R1) docking architectures on PCNA, we reveal how binding kinetics and localization precision determine the accuracy of sub‐10 nm imaging in protein nanostructures. DNA points accumulation for imaging in

Inclusion Complexes of Sunscreen Agents with β-Cyclodextrin: Spectroscopic and Molecular Modeling Studies

Journal of Spectroscopy, 2013
The inclusion complexes of selected sunscreen agents, namely, oxybenzone (Oxy), octocrylene (Oct), and ethylhexyl-methoxycinnamate (Cin) with β-cyclodextrin (β-CD) were studied by UV-Vis spectroscopy, differential scanning calorimetry (DSC), 13C NMR ...

Chewable Soft Gelatin Capsules: Design and Formulation Strategies for a Patient‐Preferred Dosage Alternative

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
Chewable softgels are a patient‐preferred alternative to conventional oral forms, offering pleasant taste, fast onset, and suitability for children or patients with swallowing difficulties. However, they present relevant challenges in their formulation: the shell must balance chewability, machinability, and stability, while the fill must mask the ...

A Simple, Ultrastable, and Cost‐Effective Oxygen‐Scavenging System for Long‐Term DNA‐PAINT Imaging

Small, Volume 22, Issue 9, 12 February 2026.
A simple, enzyme‐free, and cost‐effective oxygen scavenging system enhances DNA‐PAINT super‐resolution microscopy by increasing photostability, minimizing docking strand degradation, and enabling faster, high‐precision localizations. Its long‐term stability supports extended imaging, yielding improved spatial resolution and image quality.
