Singlet oxygen luminescence detector based on low-cost InGaAs avalanche photodiode
HardwareX, 2021 Molecular oxygen excited to singlet state (Singlet oxygen, 1O2) becomes highly reactive and cytotoxic chemical. 1O2 is commonly generated by photoexcitation of dyes (photosensitizers), including the photodynamic therapy and diagnostics of cancer. However,
