Nanoparticle thin films have emerged as a game-changing technology in the fields of medicine and biomedical imaging. These single-atom-thick layers of nanoparticles are proving to be invaluable in drug delivery and enhancing imaging techniques for medical diagnostics and treatment.
In drug delivery, nanofilms are being explored for their potential to significantly improve therapeutic outcomes. Recent research from China showcased the development of a nanoparticle thin film for the oral administration of cancer treatment. This film, utilizing graphene as a nanocarrier alongside an anticancer drug, demonstrated the potential to effectively deliver drugs to tumor tissue while limiting impact on normal tissue, showing promise for targeted and efficient drug delivery.
Furthermore, studies have shown that nanoparticle thin films, particularly those that are stimuli-responsive, hold potential for use in photothermal therapy as a potential cancer treatment. These films, using materials such as graphene oxide, can effectively target and kill cancer cells without harming healthy tissue, presenting a promising avenue for cancer therapy.
In the realm of biomedical imaging, nanoparticle thin films are enhancing imaging techniques, particularly in oncology. Their small size and efficient fluorescence efficiency make them ideal for high-contrast imaging. Additionally, the layer-by-layer technique has been used to produce graphene oxide-containing films, which have shown promise in improving fluorescent imaging, positron emission tomography (PET), and ultrasound techniques. The potential of nanoparticle thin films extends further, with research demonstrating the development.
