Archives of dermatology, 1985 A 55-year-old woman developed a dermatitis confined to light-exposed areas while taking quinidine gluconate, warfarin sodium, furosemide, spironolactone, and digoxin after cardiac surgery. Phototesting indicated a normal erythematous response to 290- to 320-nm ultraviolet radiation, but she developed erythema from 6 joules/sq cm of 320- to 400-nm ...

Fluorescence Lifetime of PDT Photosensitizers [PDF]
, 2008 Photodynamic therapy (PDn is an effective treatment option for various types of invasive tumors, the efficacy of which depends strongly on selective cell uptake and selective excitation of the tumor, which relies on proper dosage.

Advanced Science, EarlyView.This review explores how hemoglobin‐based oxygen carriers (HBOCs) combined with nanozymes create multifunctional materials that deliver oxygen while maintaining redox homeostasis. Beyond artificial blood substitutes, these constructs enable wound healing with light‐triggered oxygen release, cancer therapy through enhanced oxygenation and reactive ...

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices
Advanced Science, EarlyView.Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Advanced Science, EarlyView.A non‐covalent chirality‐induced strategy via chiral solvents is presented to synthesize helical 2D COF nanofibers with high crystallinity, high chirality, and high spin polarization. The helical structure enhances the concentration of photogenerated charges, suppresses exciton recombination, and extends carrier lifetimes, thereby significantly ...

Molecular design for efficient triplet photosensitizers [PDF]
, 2021 학위논문(박사) -- 서울대학교대학원 : 공과대학 재료공학부, 2021.8. 김재필.유기 도너 억셉터 기반 광감응제는 유가 감응형 태양전지, 열활성 지연 형광재료, 광역동치료, 삼중항-삼중항 소멸에 의한 광에너지 향상 등 다양한 분야에서 많은 관심을 받아왔다. 광감응제의 도너와 억셉터는 각각 전자를 밀어내고 당기는 능력을 갖고 있기 때문에 빛을 조사하였을 때 흡수된 전자가 도너에서 억셉터로 이동하게 되고 이는 전하분리 준위를 만들어낸다.

Advanced Science, EarlyView.We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...
