Mesoporous silica coated upconverting nanoparticles are loaded with the anticancer drug doxorubicin and grafted with ruthenium complexes as photoactive molecular valves. Drug release was triggered by 974 nm light with 0.35 W cm(-2). Such low light intensity minimized overheating problems and prevented photodamage to biological samples.
Abstract Thylakoid membranes of young leaves consist grana and stroma lamellae (stroma‐grana [SG] structure). The SG thylakoid is gradually converted into isolated (IG), almost lacking the during growth. This morphological alteration was found to cause a reduction in maximum photosynthetic rate an enhancement photoinhibition photosystem II (PSII). In situ microspectrometric measurements chlorop...
While population screening for melanoma is not recommended, those at high risk could lead to earlier detection and improved patient outcomes. Current stratification largely based on subjective clinical assessment self-report. This time-consuming dependent the experience understanding of person reporting. Therefore, improved, standardized methods are required. We developed an automated skin surf...
By eliminating the photodamage and photobleaching induced by high intensity laser fluorescent molecular, label-free scanning microscopy shows powerful capability for imaging dynamic tracing to biological tissues cells. In this review, three types of microscopies: coherent Raman scattering microscopy, second harmonic generation localized surface plasmon are discussed with their fundamentals, fea...
BACKGROUND Apoptotic cascades may frequently be impaired in tumor cells; therefore, the approaches to circumvent these obstacles emerge as important therapeutic modalities. METHODOLOGY/PRINCIPAL FINDINGS Our novel derivatives of chlorin e(6), that is, its amide (compound 2) and boronated amide (compound 5) evoked no dark toxicity and demonstrated a significantly higher photosensitizing effica...
