Ectopic pregnancy (EP) is the leading cause of maternity-related death in the first trimester of pregnancy. Approximately 98% of ectopic implantations occur in the fallopian tube, and expedient management is crucial for preventing hemorrhage and maternal death in the event of tubal rupture. Current ultrasound strategies misdiagnose EP in up to 40% of cases, and the failure rate of methotrexate treatment for confirmed EP exceeds 10%. Here the first theranostic strategy for potential management of EP is reported using a near-infrared naphthalocyanine dye encapsulated within polymeric nanoparticles. These nanoparticles preferentially accumulate in the developing murine placenta within 24 h following systemic administration, and enable visualization of implantation sites at various gestational stages via fluorescence and photoacoustic imaging. These nanoparticles do not traverse the placental barrier to the fetus or impact fetal development. However, excitation of nanoparticles localized in specific placentas with focused NIR light generates heat (>43 °C) sufficient for disruption of placental function, resulting in the demise of targeted fetuses with no effect on adjacent fetuses. This novel approach would enable diagnostic confirmation of EP when current imaging strategies are unsuccessful, and elimination of EP could subsequently be achieved using the same nano-agent to generate localized hyperthermia resulting in targeted placental impairment. 相似文献

Agricultural residues are the most available biomass resources in the world and can be exploited to produce various activated carbons at low cost. The textural properties of activated carbon, including surface area, pore size, pore size distribution, and certain surface functionalities are the main factors in the application of bio-based electrode materials for energy storage devices and electrochemical catalyst for CO2 reduction reactions, gas adsorption and separation, in water and wastewater treatment. This paper reviews the physical characteristics of activated carbons produced from various biomass resources using different methods. The effects of different activation methods, sources of biomass, and other parameters on the surface properties such as specific surface area and pore volume of activated carbon are discussed. The differences in the characteristics of activated carbon made from different agricultural biomass resources under the same parameters are evaluated. Eventually, the application of abundant agricultural residues for fabricating supercapacitors' electrode materials is also discussed. 相似文献
