“…The energy range is characteristic of phosphorene, [ 52 ] also previously reported by our group. [ 49 ] It should be noted that both of these samples were kept in Ar atmosphere, and were only exposed to air during transport and mounting at the spectroscope. Nevertheless, the time appears to be sufficient for partial phosphorene oxidation, with several oxidation forms emerging and identified as P‐O‐P and O‐P = O.…”

Few‐layer black phosphorus (FLBP) is a 2D material that gains worldwide interest for its possible applications, mainly in electronics and optoelectronics. However, as FLBP is prone to a degradation process under environmental conditions, there is a need for a monitoring method allowing investigation of its surface quality. Among many techniques, optoelectronic ones have unique advantages of fast response, non‐contact, and non‐invasive operation. In this paper, a photonic method is presented for this purpose with a focus on the earliest stages of the degradation process. Measurements are performed using a fiber‐optic interferometer working at the wavelength of 1310 nm. Series of material characterization measurements, including scanning electron microscopy, X‐ray photoelectron spectroscopy, and Raman spectroscopy investigations are performed to examine the FLBP using a well‐established methodology. Two samples—with liquid exfoliated FLBP and with layers of supernatant—prepared in two different production processes are investigated over 3 h. A detailed presentation of the degradation process is provided. The results prove that the surface monitoring of FLBP is possible by registering optical signal changes correlated with the changes in optical parameters caused by the proceeding degradation process.

Due to its unique in‐plane anisotropic structure, high carrier mobility, and adjustable direct bandgap, 2D black phosphorus (BP) has emerged as an important graphene‐like material for various micro‐ and optoelectronic, energy, catalytic, and biomedical applications. However, its lack of environmental stability severely limits its processing in ambient conditions. Chemical functionalization is an effective method for increasing the ambient stability of the material. Herein, the main approaches for chemical functionalization of 2D BP with various organic and inorganic substrates, as well as the routes for the preparation of 0D/2D and 2D/2D heterostructures, are discussed. Furthermore, the recent advances of 2D BP‐based materials in energy and catalysis fields are summarized. Finally, the challenges and future prospects for the preparation and functionalization of 2D BP are also highlighted.

The novel procedure of few-layer black phosphorus (FLBP) stabilization and functionalisation was here proposed. The cationic polymer PLL and non-ionic PEG have been involved into encapsulation of FLBP to allow sufficient time for further nanofabrication process and overcome environmental degradation. Two different spacer chemistry was designed to bind polymers to tumor-homing peptides. The efficiency of functionalisation was examined by RP-HPLC, microscopic (TEM and SEM) and spectroscopic (FT-IR and Raman) techniques as well supported by ab-initio modelling. The cell and dose dependent cytotoxicity of FLBP and its bioconjugates was evaluated against HB2, MCF-7 and MDA-MB-231 cell lines. Functionalisation allowed not only for improvement of environmental stability, but also enhances therapeutic effect by abolished the cytotoxicity of FLBP against HB2 cell line. Moreover, modification of FLBP with PLL caused increase of selectivity against highly aggressive breast cancer cell lines. Results indicate the future prospect application of black phosphorus nanosheets as nanocarrier, considering its unique features synergistically with conjugated polymeric micelles.
