A Semiconducting Polymer NanoCRISPR for Near-Infrared Photoactivatable Gene Editing and Cancer Gene Therapy
Bibliographic record
Abstract
Clustered regularly interspaced short palindromic repeat (CRISPR) gene editing has poor efficacy and off-target side effect concerns. We herein report a semiconducting polymer (SP)-based nanoCRISPR system to improve CRISPR delivery efficacy and allow for near-infrared (NIR) photoactivatable gene editing for cancer therapy. An amphiphilic SP acts as a photothermal converter, and its backbone is grafted with single-stranded deoxyribonucleic acid (DNA), which enables hybridization with single guide ribonucleic acid (sgRNA) via complementary base pairing to form sgRNA/SP-DNA. This sgRNA/SP-DNA nanosystem (nanoCRISPR) can effectively deliver sgRNA into cells and generate heat under NIR laser irradiation via the photothermal effect. The localized heat triggers the dissociation of single-stranded DNA and sgRNA to control the release of sgRNA, thereby achieving precise regulation of CRISPR activity. This NIR photoactivatable gene editing technology is able to precisely regulate the expression of green fluorescent protein (GFP) and polo-like kinase 1 (PLK1) gene for precision gene therapy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
