The new sensor uses a single CRISPR enzyme, Cas12a, to spot damaged DNA without extra steps. A specially designed double‑stranded DNA keeps Cas12a quiet until the enzyme uracil‑DNA glycosylase (UDG) removes a uracil base. When UDG cuts the uracil out, the balance of the DNA changes and Cas12a
Cancer treatment is tricky. Doctors struggle with seeing deep into tissues. They also have trouble getting clear, real-time pictures of tumors as they change during treatment. Traditional imaging methods just don't cut it. They lack the detail and speed needed to track the dynamic tumor environm
Picture this: tiny, glowing tools that can help us understand and treat diseases like cancer and brain disorders. These tools are called miniaturized fluorescent probes, and they are designed to target a specific enzyme called monoacylglycerol lipase (MAGL). MAGL is crucial because it helps control
Ovarian cancer presents a serious challenge. It is hard to catch early and even harder to treat. The low survival rates speak volumes about the need for more effective diagnostic and therapeutic tools. This is where a type of new nanomaterial -- carbon dots or CDs -- shows huge promise. Carbon do
Optical molecular imaging in clinical settings often faces a challenge: balancing patient safety with image quality. High frame rates and low excitation doses can lead to noisy images, making it crucial to find effective denoising methods. Most current deep learning techniques fall short because the
Simulating medical images with nuclear detectors, known as Monte Carlo simulation codes like SIMIND, are really handy tools for scientists. This study was all about checking if SIMIND could be a good substitute for real nuclear medicine experiments. They used a cardiac phantom, called HL, which is l
