If you have never heard of it, you can find out on our website how nanotechnologies play an important role in various fields; from the administration of drugs with nanoparticles, to regenerative medicine, to diagnostics, up to the creation of safer and less toxic pharmaceutical products.

The interaction between nanotechnology and medicine has given way to a completely new field with its own name: nanomedicine. The goal is precisely to use nanotechnological principles and tools to make a significant contribution to health.

Nanotechnology provides technology platforms and monitoring tools that can be used in terms of detection, diagnostics, bioanalysis and imaging. It also provides relevant skills and tools in the field of drug delivery and tissue engineering.

The use of quantum nanodots (or nanocrystals), semiconductor quantum dots (or semiconductor nanocrystals) and compound quantum dots for biological labeling and imaging is also growing.

Future applications include their use as fluorescent labels for cell labeling, intercellular biosensors for deep tissue and tumor imaging agents, and sensitizers for photodynamic therapy, while due to their surface chemistry, their use can be extended into biological applications due to their low cytotoxicity. Recently, there has been great interest in their applications, for the study of nanoparticles used as nanoparticle-mediated drug release.

Drug deliver

Nanoparticulate drug delivery systems increase the likelihood that a drug will reach its target, this is because instead of relying on the physicochemical properties of the drug itself to reach the destination site, they leverage a specially engineered structure that incorporates and carries the principle. pharmaceutical directly where it is needed. The characteristic of this structure is that as a nano it is extremely small and this makes it invisible to body barriers such as those of tissues.

These systems can be made for different purposes, in fact by simply changing their morphological and chemical characteristics, they can be used in the treatment of very different pathologies. For example, nanotechnological drug delivery mechanisms that are designed in research laboratories for cancer are a useful and less toxic alternative to chemo and radio therapies. These systems are equipped with the properties of nanomaterials and those of biomaterials, making them compatible with the tissues of the body, moreover they are capable of guaranteeing greater biochemical protection of the therapeutic agent, so as to prevent it from being dispersed even in tissues that are not interested. Furthermore, the novelty of these systems is not only linked to the way in which the drug is transported but also to the possibility of modulating the bioactive load, in order to control the release speed of the molecules.

Scaffold

Another important field for the application of nanotechnologies to biomedicine is that of orthopedic implants and scaffolds for tissue engineering. In this way it is possible to restore cell, tissue and organ populations. The scaffolds are indeed able to stimulate molecular cascades that activate the procedures responsible for tissue regeneration. The synthetic constructs of these scaffolds should meet certain requirements: they must be biodegradable and biocompatible to prevent long-term side effects, they must be able to bind to the cells whose tissue is to be rebuilt. As for orthopedic prostheses, for example, the use of nanotechnologies allows the construction of implants very similar to natural ones.
