Nanoporous Gold in Therapy, Drug Delivery, and Diagnostics
Nanoporous gold (np-Au) has promising applications in therapeutic delivery. The promises arise from its high surface area-to-volume ratio, ease of tuning shape and size, ability to be modified by organic molecules including drugs, and biocompatibility. For the demands of a real patient, light-triggered on-demand pulsatile release from a reservoir containing highly enriched medicines has been demonstrated to be provided by versatile drug delivery devices using nanoporous membranes made of gold nanorods and dendrimers.

Nanopore Technology in Gene Sequencing
Nanopore technology refers to nano-scale holes embedded in a thin membrane structure to detect the potential change when charged biological molecules smaller than nanopore pass through the hole. Therefore, nanopore technology has the potential to sense and analyze single-molecule amino acid, DNA, RNA, etc.. In this review, we will focus on the applications of nanopore technology in gene sequencing.

Nanoplasmonics Enabling Cancer Diagnostics and Therapy
Advances in the state of the art for early cancer detection and therapy have led to a paradigm shift in the way the disease is detected and treated. In particular, treatments have become much more targeted and localized to minimize systemic body-wide side effects common in traditional treatment methods such as chemotherapy. At the forefront of this revolution is the utilization of plasmonic gold nanoparticles, which have gained increasing attention as a highly effective nanoplatform ranging from drug delivery to plasmonics-enhanced treatments such as photothermal therapy.

Nanophotocatalysts
Biomedical waste management is getting significant consideration among treatment technologies, since insufficient management can cause danger to medicinal service specialists, patients, and their environmental conditions. The improvement of waste administration protocols, plans, and policies are surveyed, despite setting up training programs on legitimate waste administration for all healthcare service staff. Most biomedical waste substances do not degrade in the environment, and may also not be thoroughly removed through treatment processes. Therefore, the long-lasting persistence of biomedical waste can effectively have adverse impact on wildlife and human beings, as well. Hence, photocatalysis is gaining increasing attention for eradication of pollutants and for improving the safety and clearness of the environment due to its great potential as a green and eco-friendly process. In this regard, nanostructured photocatalysts, in contrast to their regular counterparts, exhibit significant attributes such as non-toxicity, low cost and higher absorption efficiency in a wider range of the solar spectrum, making them the best candidate to employ for photodegradation. Due to these unique properties of nanophotocatalysts for biomedical waste management, we aim to critically evaluate various aspects of these materials in the present review and highlight their importance in healthcare service settings.

Nanoparticles-Loaded Hydrogel System
Hydrogels are three-dimensional porous structures produced with hydrophilic polymers through physical or chemical cross-linking methods and can be prepared from a wide range of natural and synthetic polymers. Nanoparticles (NPs) are colloidal structures designed and produced to transport drugs across biological barriers. Their optimal size range is approximately between 100 and 200 nm. They protect drugs from degradation, increasing their half-life, improving drugs’ bioavailability, and providing a sustained and localized release.

Nanoparticles Used in X-Ray Photodynamic Therapy
Photodynamic therapy (PDT) has long been known as an effective method for treating surface cancer tissues. Deeper penetration of X-rays into tissues has been implemented, which is now known as X-ray photodynamic therapy (XPDT). The two methods differ in the photon energy used, thus requiring the use of different types of scintillating nanoparticles. These nanoparticles are known to convert the incident energy into the activation energy of a photosensitizer, which leads to the generation of reactive oxygen species.

Nanoparticles Migration from Food Packaging
Packaging containing nanoparticles (NPs) can increase the shelf life of products, but the presence of NPs may hazards human life. Nanomaterials that enter the body in a variety of ways can be distributed throughout the body and damage human cells by altering mitochondrial function, producing reactive oxygen, and increasing membrane permeability, leading to toxic effects and chronic disease. The diffusion and migration of nanoparticles can be analyzed by analytical techniques including atomic absorption, inductively coupled plasma mass spectrometry, inductively coupled plasma atomic emission, and inductively coupled plasma optical emission spectroscopy, as well as X-ray diffraction, spectroscopy, migration, and titration. Inductively coupled plasma-based techniques demonstrated the best results.

Nanoparticles in Polyelectrolyte Multilayer LbL
Originally regarded as auxiliary additives, nanoparticles have become important constituents of polyelectrolyte multilayers. They represent the key components to enhance mechanical properties, enable activation by laser light or ultrasound, construct anisotropic and multicompartment structures, and facilitate the development of novel sensors and movable particles.

Nanoparticles in Drug Delivery
Nanoparticles exhibit unique physical, chemical, and biological properties, which have led to their widespread applications in various fields. The properties of nanoparticles, including size, surface area, surface chemistry, optical properties, magnetic properties, and mechanical properties, can be tuned by changing the size, shape, and composition of nanoparticles. With ongoing research and development, nanoparticles are expected to play an increasingly important role in various fields, including medicine, electronics, energy, and environmental science.
