Evaluating Quantum Dot Performance in Homogeneous FRET Immunoassays for Prostate Specific Antigen

open access: yesSensors, 2016
The integration of semiconductor quantum dots (QDs) into homogeneous Förster resonance energy transfer (FRET) immunoassay kits for clinical diagnostics can provide significant advantages concerning multiplexing and sensitivity.

Distance‐Dependent Energy Transfer Between Organic Fluorophores and Single‐Walled Carbon Nanotubes

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 12, 16 March 2026.
We demonstrate that the dsDNA part adopts a perpendicular orientation to the SWCNT and present a distance‐dependent energy transfer of single fluorescent dyes to SWCNTs. Carbon nanotube energy transfer (CNET) obeys a d−5 distance dependence with a characteristic distance of 7.4 nm (± 0.7 nm) for 50 % energy transfer.

Differential virulence and immune recognition of Klebsiella pneumoniae O-antigen subtypes O2α and O2β

open access: yesInfection and Immunity
Klebsiella pneumoniae infections are sharply on the rise among at-risk populations. K. pneumoniae has nine serogroups of O-antigens. Recently, additional O-antigen subtypes within these serogroups have been identified; the contributions of these subtypes

Proximity‐Induced Ligation of Noncomplementary Oligonucleotides Triggered by Charge‐Transfer Interactions

open access: yesChemistryEurope
While DNA‐templated ligations typically rely on the sequence‐specific hybridization of complementary strands to bring reactive groups into close proximity, charge‐transfer assisted ligation (CTAL) is proposed as a fundamentally different strategy. Rather

One‐Pot Transition‐Metal‐Free Methods for the Synthesis of All Three Bonds of the Alkyne's Triple Bond

open access: yesChemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
One‐pot transition‐metal‐free methods for the synthesis of all three bonds of the alkyne's triple bond are reviewed. After analysis of several named reactions and discussion of improvements, recent advances in the synthesis of alkynes are discussed. Each section contains a proposed reaction mechanism and analysis of the strengths and weaknesses of the ...

Peptomer Linkers Enable Kinetic Control over Co‐Delivery of Multiple Chemotherapeutics

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 11, 20 March 2026.
A key challenge in combinatorial chemotherapeutic drug delivery is independent control over release kinetics, especially with drugs of similar size and structure. Here, peptoid substitutions to proteolytically degradable peptides enabled the design of fast and slow‐releasing drug linkers.

Directed Functionalization of Recombinant Spider Silk Nonwoven Membranes with Antibodies Using Non‐Canonical Amino Acids

open access: yesAdvanced Materials, Volume 38, Issue 14, 6 March 2026.
A recombinant spider silk protein was functionalized by incorporating genetically encoded bio‐orthogonal reactive azido‐groups. The azido‐functionalized proteins were produced in a scalable biotechnological process, and particles, films, as well as nanofibers were established as anchorage for fully functional antibodies via site‐specific bio‐orthogonal
