Caltech scientists have developed DNA origami-based sensors for rapid protein detection in bodily fluids, paving the way for affordable lab-free testing.

"Our work provides a proof-of-concept showing a path to a single-step method that could be used to identify and measure nucleic acids and proteins," says Paul Rothemund ... used to create shapes ...

Imagine if antibodies, proteins such as insulin, or even COVID-19 and flu vaccines could be consumed orally instead of via injection. This vision is closer than ever, according to a new study by ...

WE have formulated a structure for the nucleic acids which is compatible with the main features of the X-ray diagram and with the general principles of molecular structure, and which accounts ...

which can predict protein structure from a protein's amino acid code, the linear string of building blocks within it that folds to create its structure. AlphaFold and models like it have become widely ...

An example of this is the trp operon which contains structural genes coding for proteins that create tryptophan, an amino acid. The trp operon shown below illustrates a summary of how the ...

The seemingly limitless diversity of proteins in nature arose from only a few thousand ... These fragments are widespread in the most ancient folds and enriched for iron-sulfur- and nucleic ...
