PDT with ML8500 combined to ML7710 resulted in effective in vitro cytotoxicity and with ML7710 in vivo, which was further potentiated with PD-L1 immune checkpoint inhibitors.   Read the article Continue reading →

Motivation of the study In photodynamic therapy (PDT), systemically administered photosensitizer is activated within the tumor using focused near-infrared light, typically a laser with a wavelength matching the absorption peak of the photosensitizer. Several photosensitizers have been clinically approved for the treatment of different cancers; however, their accumulation is non-tumor exclusive which exposes healthy tissues to side effects like daylight-induced phototoxicity. A promising strategy to improve tumor selectivity is to couple photosensitizer to a tumor-targeting agent that binds to a specific antigen expressed on the Continue reading →Customer case Research by: Duke University, founded in 1924, is one of the leading and wealthiest private research universities in the USA.

Published in: ACS Biomaterials Science and Engineering Authors: Rahul S. Tade, Pravin O. Patil  Published in: ACS Biomaterials Science and Engineering Authors: Rahul S. Tade, Pravin O. Patil   Breast cancer (BC) is increasing as a significant cause of mortality among women. In this context, early diagnosis and treatment strategies for BC are being developed by researchers at the cellular level using advanced nanomaterials. However, immaculate etiquette is the prerequisite for their implementation in clinical practice. Considering the stolid nature of cancer, combining diagnosis and therapy (theranostics) using graphene quantum dots (GQDs) is a prime focus and challenge for Continue reading →
