Theranostic nanoplatform for high‐performance dual‐modal magnetic resonance imaging‐guided therapy of orthotopic hepatocellular carcinoma

open access: yesBMEMat, EarlyView.
This article introduces a biomimetic Mn‐doped polydopamine nanoplatform (HAMM NPs) coated with cancer cell membranes. It enables targeted hepatocellular carcinoma theranostics via T1/T2 dual‐mode magnetic resonance imaging and tumor microenvironment‐triggered sonodynamic therapy/chemodynamic therapy, achieving potent antitumor efficacy in subcutaneous ...

Protein hydrolysates in cell culture: Toward multi‐omics characterization

open access: yesBiotechnology Progress, EarlyView.
While protein hydrolysates are widely used in cell culture applications, they remain undefined and variable products. Multi‐omic characterization evaluating composition and function can transition hydrolysates toward semi‐defined media components.

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

open access: yesArchaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

DSSC Anchoring Groups: A Surface Dependent Decision [PDF]

open access: yes, 2014
Electrodes in dye sensitised solar cells (DSSCs) are typically nanocrystalline anatase TiO2 with a majority (101) surface exposed. Generally the sensitising dye employs a carboxylic anchoring moiety through which it adheres to the TiO2 surface.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

open access: yesChemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Fluorescent Diarylethenes With Polar Groups: Synthesis, Spectra, and Optical Microscopy Applications

open access: yesChemistry – A European Journal, EarlyView.
Blinking green and flashing red: photo‐switchable and photo‐activatable probes emitting green and red light were prepared and applied as bioconjugates in super‐resolution optical microscopy. ABSTRACT The use of photoactivatable fluorescent diarylethenes (fDAEs) in biology‐related light microscopy has been restricted by the lack of probes having freely ...

Non-Empirically Tuned Range-Separated DFT Accurately Predicts Both Fundamental and Excitation Gaps in DNA and RNA Nucleobases [PDF]

open access: yes, 2012
Using a non-empirically tuned range-separated DFT approach, we study both the quasiparticle properties (HOMO-LUMO fundamental gaps) and excitation energies of DNA and RNA nucleobases (adenine, thymine, cytosine, guanine, and uracil).
