The efficacy of antimicrobial photodynamic therapy, using various distinct photosensitizers, has been studied since the 1990s. [ 9 ] [ 7 ] Most studies have yielded positive outcomes, often achieving disinfection levels, as defined by infection control guidelines, exceeding 5 log 10 (99.999%) of microbial inactivation.

Photodynamic therapy (PDT) is a form of phototherapy involving light and a photosensitizing chemical substance used in conjunction with molecular oxygen to elicit cell death (phototoxicity). [ 1 ] PDT is used in treating acne , wet age-related macular degeneration , psoriasis , and herpes .
Examples of biomedical optics techniques and technologies include optical coherence tomography (OCT), fluorescence microscopy, confocal microscopy, and photodynamic therapy (PDT). OCT, for example, uses light to create high-resolution, three-dimensional images of internal structures, such as the retina in the eye or the coronary arteries in the ...
Photodynamic therapy (PDT) is a form of phototherapy using nontoxic light-sensitive compounds (photosensitizers) that are exposed selectively to light at a controlled wavelength, laser intensity, and irradiation time, whereupon they generate toxic reactive oxygen species (ROS) that target malignant and other diseased cells.
In the United States, a pattern day trader is a Financial Industry Regulatory Authority (FINRA) designation for a stock trader who executes four or more day trades in five business days in a margin account, provided the number of day trades are more than six percent of the customer's total trading activity for that same five-day period.

Huang et al. investigated the feasibility of using gold nanorods for both cancer cell imaging as well as photothermal therapy. [2] The authors conjugated antibodies (anti-EGFR monoclonal antibodies) to the surface of gold nanorods, allowing the gold nanorods to bind specifically to certain malignant cancer cells (HSC and HOC malignant cells).
