DNA Origami‐Templated Aptamer Chiral Structures Realize Cellular Enantioselectivity

Advanced Materials, EarlyView.
Aptamers displayed on tubular DNA origami nanostructures in defined chiral orientations (left‐ or right‐handed) exhibit enantioselective interactions with cell surface target proteins. While the right‐handed configuration supports only transient binding, the left handedness energetically favors protein dimerization and promotes subsequent ...

DNA Nanostructure‐Templated Multivalency Enables Broad‐Spectrum Virus Inhibition

Advanced Science, EarlyView.
A honeycomb‐shaped DNA nanostructure is introduced that organizes nanobodies or aptamers into trimeric clusters mirroring the native hemagglutinin arrangement on influenza viruses. This geometry‐matched multivalency enhances binding avidity by up to 1000‐fold, resulting in robust, broad‐spectrum viral neutralization and a 30–55% improvement in host ...

APOE‐stratified Proteomic and Metabolomic Analysis Reveals Mitochondrial Dysfunction Inflammation and Lipid Dysregulation in Alzheimer's Disease

Advanced Science, EarlyView.
A large‐scale multiomic dataset (proteomic and metabolomic) comprising 3,060 plasma samples were analyzed to identify proteins, metabolites, pathways, and protein‐associated drugs linked to Alzheimer’s Disease (AD) independently of apolipoprotein E (APOE). AD was associated with a distinct molecular signature that captures.

Design and Characterization of DX‐Tile DNA Nanostar‐Based Hydrogels

Advanced Science, EarlyView.
In this study, the authors demonstrated that DNA DX‐tile‐based multi‐arm motifs can be used to assemble pure DNA hydrogels, offering greater design flexibility and enhanced control over their mechanical properties and functionalization capabilities compared to single duplex‐based DNA hydrogels.

DNA Nanoflower LYTACs Enable Efficient VEGF Degradation and Verteporfin Loading for Combined Therapy of Wet Age‐Related Macular Degeneration

Advanced Science, EarlyView.
An integrated approach that combines a DNA nanoflower VEGF degrader with photodynamic therapy is developed for the treatment of wet age‐related macular degeneration, which reduces the risk of VEGF reactivation‐induced CNV recurrence and minimizes the systemic side effects associated with photodynamic therapy.

Stimuli‐Responsive Supramolecular Biomaterials for Cancer Theranostics

Advanced Science, EarlyView.
The ultimate goal of cancer theranostics is to get imaging agents and therapeutic cargo to tumor sites when and where they are required. “Smart” systems should be developed. This review discusses the characteristics of physiological stimuli, types and action modes of external stimuli, construction approaches and working principles, as well as ...

Efficient Reverse Transcription Using Locked Nucleic Acid Nucleotides towards the Evolution of Nuclease Resistant RNA Aptamers

PLoS ONE, 2012
Modified nucleotides are increasingly being utilized in the de novo selection of aptamers for enhancing their drug-like character and abolishing the need for time consuming trial-and-error based post-selection modifications. Locked nucleic acid (LNA) is one of the most prominent and successful nucleic acid analogues because of its remarkable properties,

A Novel Aptamer LL4A Specifically Targets Vemurafenib-Resistant Melanoma through Binding to the CD63 Protein. [PDF]

, 2019
Melanoma is a highly aggressive tumor with a poor prognosis, and half of all melanoma patients harbor BRAF mutations. A BRAF inhibitor, vemurafenib (PLX4032), has been approved by the US Food and Drug Administration (FDA) and European Medicines Agency ...

MARPLE: A Proximity‐Triggered CRISPR‐Cas13 Platform for Ultrasensitive Antibody Detection

Advanced Science, EarlyView.
MARPLE is a modular CRISPR‐Cas13 immunoassay that uses antibody‐induced proximity to trigger a toehold‐exchange reaction, releasing an RNA activator for Cas13. This one‐pot, isothermal architecture enables ultrasensitive (femtomolar) and highly specific detection of diverse antibodies, including therapeutic, pathogen‐specific, and cancer‐associated ...
