“…Many different routes have been explored to synthesize NMs and NPs, from deposition of polymeric films [19,21,45,[49][50][51] with incorporated bactericidal agents [21,[52][53][54][55], or metallic or oxide films [2,21,56,57], to metal decoration of nanostructures [58][59][60]. The strategies are based on wet synthesis (spin-coating [61], sol-gel [57,61,62]), photochemical [52], biological [63][64][65], biotechnological [24] and physical methods (laser ablation [66], magnetron sputtering (MS) [2,44,[67][68][69], gas phase beams [70,71]). Surprisingly, the literature available on nanostructured coatings obtained by physical methods is scarce.…”

Counteracting the spreading of multi-drug-resistant pathogens, taking place through surface-mediated cross-contamination, is amongst the higher priorities in public health policies. For these reason an appropriate design of antimicrobial nanostructured coatings may allow to exploit different antimicrobial mechanisms pathways, to be specifically activated by tailoring the coatings composition and morphology. Furthermore, their mechanical properties are of the utmost importance in view of the antimicrobial surface durability. Indeed, the coating properties might be tuned differently according to the specific synthesis method. The present review focuses on nanoparticle based bactericidal coatings obtained via magneton-spattering and supersonic cluster beam deposition. The bacteria–NP interaction mechanisms are first reviewed, thus making clear the requirements that a nanoparticle-based film should meet in order to serve as a bactericidal coating. Paradigmatic examples of coatings, obtained by magnetron sputtering and supersonic cluster beam deposition, are discussed. The emphasis is on widening the bactericidal spectrum so as to be effective both against gram-positive and gram-negative bacteria, while ensuring a good adhesion to a variety of substrates and mechanical durability. It is discussed how this goal may be achieved combining different elements into the coating.

Cardiovascular diseases (CVDs) are a primary cause of death globally. A few classic and hybrid treatments exist to treat CVDs. However, they lack in both safety and effectiveness. Thus, innovative nanomaterials for disease diagnosis and treatment are urgently required. The tiny size of nanomaterials allows them to reach more areas of the heart and arteries, making them ideal for CVDs. Atherosclerosis causes arterial stenosis and reduced blood flow. The most common treatment is medication and surgery to stabilize the disease. Nanotechnologies are crucial in treating vascular disease. Nanomaterials may be able to deliver medications to lesion sites after being infused into the circulation. Newer point-of-care devices have also been considered together with nanomaterials. For example, this study will look at the use of nanomaterials in imaging, diagnosing, and treating CVDs.

“…Antimicrobial nanoparticles have been reported to be applied to mechanical valves to prevent infection of prosthetic heart valves after heart valve replacement. Angelina et al (112) coated the surface of pyrolyric carbon (PyC) on a prosthetic heart valve with a thin film of AgNPs to inhibit bacterial colonization. AgNPs are capable of interfering with the cell membrane and affecting bacterial viability.…”

“…AgNPs are capable of interfering with the cell membrane and affecting bacterial viability. Furthermore, roughness at the nanoscale owing to the coating of Ag-NPs on the PyC heart valve surface contributes to preventing bacterial adherence to the surface (112). Therefore, nanoparticles with antimicrobial properties are capable of inhibiting bacterial growth, which shows a promising future for the use of nanoparticles for IE and other chronic infectious diseases.…”

INTRODUCTIONNanotechnology is a novel method of producing and manipulating substance at the molecular scale, which can provide for more efficiently functioning mechanical, chemical, and biological components and bring great value to the development of medicine (1). The term "nano," first presented by the famous material scientist Richard P. Feynman (2) in 1959, is a unit used to describe 10 −9 of parameter in the microcosm. Over the past few years, nanotechnology has sparked intense interest among scientists and has been used to overcome biomedical difficulties and treat various diseases such as cancers (3), infectious diseases (4), and cardiovascular diseases (5). Nanoparticles, nano-carriers or nano-materials, defined as substances with a size of 1 to 100 nm, have specific functions at the cellular, atomic and molecular levels and are widely used in the fields of diagnosis and treatment of diseases (6). Nanoparticles or nano-carriers exhibit many advantages, including excellent drug stability and solubility, prolonged half-life of drug systemic circulation, stable and sustained drug-releasing rate, and lower frequency of drug administration, thus minimizing side effects of drug (6). As a result, they have become a promising alternative strategy to improve drug efficiency and minimize side effects in the treatment of diseases.Infective endocarditis (IE) is an infectious disease defined by an infection of the heart valve and the endocardial surface, such as a prosthetic heart valve or an indwelling cardiac device (7). IE remains an infectious and life-threatening disease with an incidence of approximately 3-10 per 100,000 person-years (8, 9). With more prosthetic valve replacements or cardiac electronic device implantations performed for patients who suffer from heart valve diseases or arrhythmia, the incidence of IE is rising (8). IE is still a challenging disease bringing stupendous health and economic burden to the world.With IE recognized as an infectious disease characterized by biofilm formation, the core of antimicrobial therapy for IE has focused on eradicating biofilm and drug-resistant bacteria.
