In this installment, I primarily discuss considerations to keep in mind when choosing buffering additives that will be used ...

Absorption spectra obtained at higher oxygen concentrations revealed the spectrum of a new species, which we interpret as that of a naphthalene-oxygen charge-transfer complex. The binding energy of ...

An optical spectroscopic technique, surface-enhanced Raman spectroscopy (SERS), mostly used in the research setting for liquid sample analysis, has recently been applied to breath-based diagnostics.
