Feasibility of quantitative determination of doxorubicin with surface-enhanced Raman spectroscopy

, 2001
Surface-enhanced Raman spectroscopy (SERS) was performed using excitation at 488 nm in a blood plasma-doxorubicin-silver colloid system. With a blood plasma content of 1%, a partial least-squares calibration of the doxorubicin was made in the 10-750 nM ...

Unique Role of Microstructure of a Bioimplant Zinc Alloy and Protein Content of Simulated Body Fluid in Corrosion and Fracture

Advanced Functional Materials, EarlyView.
BSA addition to physiological solutions enhances resistance of a Zn alloy to stress corrosion cracking (SCC) but reduces its corrosion resistance. Extended surface characterization explains the contrasting influences on corrosion and SCC. Unexpectedly, the alloy suffers transgranular SCC (TGSCC), despite extensive grain boundary precipitation. Thorough

Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

Advanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

High‐Efficiency Quantum Defect Generation in Carbon Nanotubes via Oxygen‐Free Photochemistry

Advanced Functional Materials, EarlyView.
We show that oxygen plays an important role in quantum defect formation in carbon nanotubes and identify reaction conditions to create a range of different quantum defects for photonics and biosensing. ABSTRACT Single‐walled carbon nanotubes (SWCNTs) offer potential for a wide range of applications from optoelectronic devices to biomedical diagnostics.

Surface enhanced Raman spectroscopy of biomolecules in buffer solution

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
Controlled creation of SERS-active hot spots in liquid is a challenge in which optical forces can play an important role by promoting the aggregation of metal nanoparticles by optical trapping or by exploiting the radiation pressure.

Particle‐Level ZrO2 Atomic Layer Deposition Enables Fast‐Cycling and Long‐Life Graphite Cathodes for Dual‐Ion Batteries

Advanced Functional Materials, EarlyView.
A spatial location of atomic layer deposition (ALD)‐derived ZrO2 coatings is demonstrated to be a critical design parameter for stabilizing graphite cathodes in DIBs. Direct particle‐level ALD (PALD) screening of representative metal oxides identified ZrO2 as the coating that provides the most favorable balance of high‐rate capability and interfacial ...
