Large-scale sensitivity adjustment for Gd-HMME room temperature phosphorescence oxygen sensing
Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2022The oxygen sensing enhancement based on room temperature phosphorescence (RTP) of Gd-HMME adjusted by imidazole was studied. The phosphorescence intensity IP0 and the Stern-Volmer equations under different imidazole concentration were obtained, and the physical mechanism of imidazole regulating the oxygen quenching constant KSV was analyzed.

Growth inhibition effect of HMME-mediated PDT on hepatocellular carcinoma HepG2 cells
Lasers in Medical Science, 2014Photodynamic therapy (PDT) is considered a promising new strategy for liver cancer treatment. Three elements of PDT--optical output power, irradiation time, and photosensitizer concentration--play important roles in promoting cell death. This research aimed to characterize the effects of hematoporphyrin monomethyl ether (HMME)-based PDT on ...

Sonodynamic therapy (SDT), which involves the activation of sonosensitizers to generate cytotoxic reactive oxygen species under ultrasound irradiation, is a promising noninvasive modality for cancer treatment. However, the clinical translational application of SDT is impeded by the lack of efficient sonosensitizers, the inefficient accumulation of ...

Inactivation of bovine immunodeficiency virus by photodynamic therapy with HMME
Chinese Optics Letters, 2008To investigate the effect of photodynamic therapy (PDT) with hematoporphrin monomethyl ether (HMME) on bovine immunodeficiency virus (BIV) can provide the basis theory for photoinactivation of human immunodeficiency virus (HIV). To assess the protection of HMME-PDT on the cell line Cf2Th infected with BIVR29 by 3-(4,5)-dimethylthiahiazol-2-y1-3,5-di ...

Effect of concentration on photobleaching of hematoporphrin monomethyl ether (HMME) in solutions
SPIE Proceedings, 2010To analyze the effect of concentration on the photobleaching of HMME, the loss of HMME absorption in simplex solution (PBS) and complex solution (albumin buffer) was monitored using steady-state absorption spectra during 532nm laser irradiation. Three concentrations (4, 10, 80μmol/L) were set for each type solution.

We report on some of the optical properties of hematoporphyrin monomethyl ether (HMME), a relatively new photosensitizer that has been in clinical trials in China since the early 1990s. We characterized the photosensitizer on the basis of one photon absorption and emission.
