Abstract

Tip‐enhanced Raman spectroscopy (TERS) is a powerful nano‐optical approach that allows the extraction of nanometer resolved chemical information. The key to a successful TERS measurement is the quality of the TERS tip. However, tip contamination, which usually occurs during measurements on samples that include organic molecules or after long‐term storage, remains a critical problem for TERS experiments. It not only affects the reliability of TERS results but also hinders the long‐term development of the TERS technique. Herein, we propose a method that enables the regeneration of contaminated TERS tips. For this purpose, we prepared a TERS tip contaminated by stable organic molecules, which was subjected to a simple and rapid ultraviolet (UV) cleaning procedure to remove the contaminants and to regenerate the tip. This method is demonstrated to be effective in removing the contaminants from the TERS tip by directly breaking the bonds in the contaminated molecules and oxidizing organic compounds with the generated reactive oxygen atom. This simple method could propel the development of the TERS technique. [ABSTRACT FROM AUTHOR]

Abstract

Nanographene C 222 , which consists of a planar graphenic plane containing 222 carbon atoms, holds the record as the largest planar nanographene synthesized to date. However, its complete insolubility makes the processing of C 222 difficult. Here we addressed this issue by introducing peripheral substituents perpendicular to the graphene plane, effectively disrupting the interlayer stacking and endowing C 222 with good solubility. We also found that the electron-withdrawing substituents played a crucial role in the cyclodehydrogenation process, converting the dendritic polyphenylene precursor to C 222 . After disrupting the interlayer stacking, the introduction of only a few peripheral carboxylic groups allowed C 222 to dissolve in phosphate buffer saline, reaching a concentration of up to 0.5 mg/mL. Taking advantage of the good photosensitizing and photothermal properties of the inner C 222 core, the resulting water-soluble C 222 emerged as a single-component agent for both photothermal and photodynamic tumor therapy, exhibiting an impressive tumor inhibition rate of 96%.
