Abstract

fetched live from OpenAlex

Abstract DNA‐based enzymes, also known as deoxyribozymes or DNAzymes, are single‐stranded DNA molecules with catalytic activity. DNAzymes do not exist in nature but can be isolated from random‐sequence DNA pools using in vitro selection. To date, many DNAzymes that collectively catalyze a diverse range of chemical transformations have been reported. Here, examples of new DNAzymes engineered to mimic some intriguing functions of naturally occurring protein‐based enzymes are discussed. This is followed by discussions of recent examples of a particular class of DNAzymes, known as “RNA‐cleaving DNAzymes”, that have been derived specifically so that their activity is strictly dependent on a given chemical or biological stimulus. Some unique ways to employ ligand‐responsive DNAzymes for the design of bioanalytical assays and biosensors are then highlighted. Being DNA molecules, DNAzymes have proven to be entirely compatible with DNA amplification. Several approaches are then discussed, which relay the activity of an analyte‐activated DNAzyme into the production of massive amounts of DNA amplicons, via “rolling circle amplification”, in biosensing applications designed to deliver very high levels of detection sensitivity.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
