Researchers have created a water-soluble fluorescent spray that can visualize latent fingerprints in just ten seconds. The new dye-based technology is non-toxic, biologically compatible, and reduces the risk of damaging DNA evidence.
Researchers developed a machine learning-based method to estimate chemical attributes of spice extracts by measuring fluorescence emitted by polyphenols and flavonoids. The approach integrated data from multiple dilution levels, achieving highly accurate results.
Researchers develop a new technique to detect circulating tumor cells in blood, overcoming noise issues with existing methods. The dual-ratio approach enhances penetration range and accuracy, paving the way for quicker diagnosis of metastasis.
A novel fluorescence probe successfully quantifies trace components like hydrogen sulfide in whole blood, overcoming autofluorescence interference. The probe uses a borodipyrromethene-based dye that quenches the interfering light, allowing for accurate measurements.
Researchers have found a possible new target for therapies aimed at treating age-related neurological diseases by linking increased presence of immune cells to conditions like Alzheimer's disease. Microglia, specialized immune cells in the brain, can adopt a dysfunctional state that contributes to neurodegenerative diseases.
Researchers developed a multimodal imaging-based tool, the active biopsy guidance system (ABGS), to improve oral cancer diagnosis. The ABGS provides clinically actionable direct visible guidance for biopsies, enhancing precision and potentially saving lives.
Mount Sinai researchers discovered that age-related macular degeneration (AMD) may be caused by two distinct types of deposits in the retina: drusen and subretinal drusenoid deposits (SDDs). Early intervention with vitamin supplements can slow down drusen formation, while SDDs pose a greater threat to advanced AMD.
A Brazilian research team has developed a novel method to sort specialty and standard coffee beans using multispectral imaging and machine learning. The technique, which does not require roasting or human intervention, uses images of the beans at different wavelengths to distinguish between quality levels.
Researchers at the University of Bonn have tested color-coded fundus autofluorescence as a supportive novel diagnostic method for posterior uveitis. The results indicate that this ratio can be very characteristic and helpful in differentiating various posterior uveitis subtypes.
A team of Brazilian researchers has developed a novel technique using light and artificial intelligence to identify the maturity stages of soybean seeds. The method utilizes chlorophyll fluorescence and machine learning algorithms to classify commercial seeds with high accuracy. This innovation avoids destroying seeds, which are then c...
Researchers developed a novel biologically-inspired intraoral camera with a wide-angle insect eye structure, increasing field of view and resolving optical aberrations. The device provides multifunctional dental imaging, including high dynamic range, 3D depth, and autofluorescence, without discomfort or image blur.
Researchers developed a cost-effective protocol for plant sample preparation and visualization, eliminating the need for stains and dyes. The new method harnesses the natural autofluorescence of tissues in plants, allowing for rapid visualization of plant anatomy across diverse taxa.
A new study describes a novel label-free imaging technique that can differentiate active T cells from those in a quiescent state. The method, which uses autofluorescence detection, is non-damaging and doesn't alter the behavior of the cell, offering advantages over traditional antibody-based methods.
Researchers found increased AGE levels in eyes of people with type 2 diabetes and prediabetes, indicating potential for early detection through lens autofluorescence measurement. A new biomicroscope can detect these levels without invasive procedures.
Researchers found that non-invasive skin autofluorescence measurement can predict future risk of type 2 diabetes, cardiovascular disease, and mortality. A single measurement was associated with a 3-fold increase in risk of type 2 diabetes or CVD.
Researchers have developed a non-destructive sensing method to determine fish freshness in frozen state using autofluorescence spectroscopy. This technique offers high sensitivity and accuracy, allowing for rapid detection of freshness conditions.
The National Institute of Standards and Technology (NIST) is developing testing standards for lab-on-a-chip devices to ensure accurate measurements and product quality. Key findings include the importance of controlling multiple factors, such as materials and measurement methods, in determining autofluorescence levels.
