Heart failure (HF) represents a cardiovascular disease that significantly threatens global well‐being and quality of life. Electroactive nanomaterials, characterized by their distinctive physical and chemical properties, emerge as promising candidates for HF prevention and management. This review comprehensively examines electroactive nanomaterials and their applications in HF intervention. It presents the definition, classification, and intrinsic characteristics of conductive, piezoelectric, and triboelectric nanomaterials, emphasizing their mechanical robustness, electrical conductivity, and piezoelectric coefficients. The review elucidates their applications and mechanisms: 1) early detection and diagnosis, employing nanomaterial‐based sensors for real‐time cardiac health monitoring; 2) cardiac tissue repair and regeneration, providing mechanical, chemical, and electrical stimuli for tissue restoration; 3) localized administration of bioactive biomolecules, genes, or pharmacotherapeutic agents, using nanomaterials as advanced drug delivery systems; and 4) electrical stimulation therapies, leveraging their properties for innovative pacemaker and neurostimulation technologies. Challenges in clinical translation, such as biocompatibility, stability, and scalability, are discussed, along with future prospects and potential innovations, including multifunctional and stimuli‐responsive nanomaterials for precise HF therapies. This review encapsulates current research and future directions concerning the use of electroactive nanomaterials in HF prevention and management, highlighting their potential to innovating in cardiovascular medicine.

Vanadium pentoxide (V2O5) thin films were grown on porous silicon (PS) layer by electron beam evaporation technique under an oxygen partial pressure. The morphology of the porous surface before and after V2O5 deposition for different evaporation times was observed by the Scanning Electron Microscope (SEM). The predicts changes of the chemical composition and bonds at the porous surface have been studied by FTIR and Raman spectroscopies. Photoluminescence (PL) spectroscopy was carried out to study the effect of vanadium pentoxide thickness on the optical properties of V2O5/PS nanocomposites. The PL spectrum of PS show a red-shift of 90 nm following the deposition of vanadium pentoxide while a quenching of the PL intensity was observed. Referring to FTIR and Raman results, the origin of this shift can be attributed to the formation of oxidized vanadium elements at PS surface as well as the creation of localized states by V2O5 molecules inside the band gap of PS. The wavelength dependence of optical transmittance, reflectance and absorption coefficients were investigated. An increase in the optical band gap from 1.95 eV to 2.18 eV was obtained due to Moss-Burstein effect as well as the presence of vacancy defects in V2O5 film.
