Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy

open access: yesAdvanced Functional Materials, EarlyView.
In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.

Enhanced Near-Infrared-Excitable Organic Afterglow Nanoparticles for Deep-Tissue Multimodal Imaging via Singlet Oxygen-Mediated Energy Transfer

open access: yesResearch
Afterglow imaging offers exceptional signal-to-background ratios (SBRs) by circumventing real-time excitation and autofluorescence, yet conventional systems rely on visible-light excitation, limiting tissue penetration and signal intensity.

Size-selective molecular recognition based on a confined DNA molecular sieve using cavity-tunable framework nucleic acids

open access: yesNature Communications, 2020
Size-selective discrimination is an issue in biosensing. Here, the authors report on a size selective DNA nanocage which excludes agents based on size and protects the probes against degradation, and demonstrate the discrimination between mature and ...

Engineering an asymmetric rhodamine dye suitable for developing ratiometric fluorescent probe

open access: yesSmart Molecules, 2023
Fluorescent probes based on rhodamine skeleton are extensively used in biological imaging. However, the construction of ratiometric fluorescent probes based on the rhodamine skeleton without introducing additional fluorophores is still challenging ...

Biosensing platform combining label-free and labelled analysis using Bloch surface waves [PDF]

open access: yes, 2015
Bloch surface waves (BSW) propagating at the boundary of truncated photonic crystals (1D-PC) have emerged as an attractive approach for label-free sensing in plasmon-like sensor configurations.

Classification of analytics, sensorics, and bioanalytics with polyelectrolyte multilayer capsules [PDF]

open access: yes, 2020
Polyelectrolyte multilayer (PEM) capsules, constructed by LbL (layer-by-layer)-adsorbing polymers on sacrificial templates, have become important carriers due to multifunctionality of materials adsorbed on their surface or encapsulated into their ...

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

open access: yesAdvanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

General (hetero)polyaryl amine synthesis via multicomponent cycloaromatization of amines

open access: yesNature Communications
(Hetero)polyaryl amines are extensively prevalent in pharmaceuticals, fine chemicals, and materials but the intricate and varied nature of their structures severely restricts their synthesis. Here, we present a selective multicomponent cycloaromatization

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.
