Povidone Iodine (PVPI) is a well known broad spectrum anticeptic for wound treatment and irrigation. PVPI, however, is a very hydrophilic substrance having poor resistance against water. Wound treatments with PVPI are, therefore, short lived. We have developed a simple and inexpensive method to directly incorporate PVPI in alginic (sodium & calcium) polymer matrices to enable its slow and controlled release into infected areas. The process also prolongs antiseptic effects of PVPI considerably. Aqueous PVPI solutions are blended with sodium alginate solutions at any proportion from which films can be cast. Droplets or continuous liquid streams of the blend solutions can be cross-linked in calcium salt solutions to form PVPI encapsulated beads and fibers.
A complete Lab-On-Chip (LOC), based on a microfluidic piezoelectric chip able to steer surface acoustic waves (SAWs) passively and with minimal losses depending on the position of the fluid microdroplets on the chip. LOCs are one of the most promising technologies in the biomedical field. Miniaturized, portable diagnostic and analysis system are expected to constitute the next-generation tool for medicine and other fields. The liquid handling system is at the base of every LOC. It must enable loading, actuation and precise positioning of very small liquid volumes. LOC technologies are attracting the biomedical market thanks to the new capabilities introduced by the microfluidic chips and by optimized performances in terms of liquid consumption, waste production, scalability and high-throughput analysis.
A structure based on 30 nm gold nanospheres conjugated to (bio)molecules by a triazole ring formed through click-chemistry is developed. 30 nm gold nanospheres (AuNs) offer a number of attractive properties such as maximum efficiency in terms of cellular uptake, and an extinction band peaked at 530 nm. The AuNs are coated with an alkyne-modified peptide (CLPFF-Propargylglycine; G), in order to obtain stable bifunctionalized gold colloids with both carboxylic acid and alkyne groups on the metallic surface (AuNsG), so that the system can be easily conjugated with multiple molecular species. The alkyne groups can be readily coupled to azide-probes, such as azide-fluorescein (Fn), by click-chemistry reactions, obtaining the 1,2,3-triazole ring linkage between the metallic nanostructures and the probe. Owing to the field enhancement effect occurring in proximity of the metallic nanostructure for the localized surface plasmon resonance (LSPR) stimulation, this system can effectively release the probe through a 3-photons effect by irradiation with 561-nm laser light. In this way it is possible to control both spatially and temporally the release of a probe internalized in living cells by the use of visible light close to the red part of the spectrum.
In the research field of the Cognitive Sciences, the RBCS department has developed compact multi-channel single and multi-unit in vivo neural recording system. This device permits both a very precise electrode positioning with respect of the brain tissue and the application of a finely, dinamically controlled pressure in the recording site. This device allows the surgeon to monitor the pressure exerted by the recording device on the brain tissue while a separate control adjust gradually this pressure, dynamically following and limiting the brain tissue bulging and pulsation. In this way dangerous interruptions of brain blood supply in the recording site due to excessive pressure produced by the recording device are avoided while brain pulsations are reduced.

Method to synthesize in aqueous solution branched gold nanoparticles by which it is possible to control the size and the degree of branching at the same time. The method does not use cytotoxic capping agents, such as CTAB, organic thiol molecules or others. A further coating can also be realized on the surface of branched nanoparticles. It also allows to control with extreme precision the optical properties of the nanoparticles in a broad region of UV-visible and near-ir spectrum. The nanoparticles can be used for application based on the Surface Enhanced Raman Scattering phenomenon, or as Metal Enhanced Fluorescence or Metal Enhanced Chemiluminescence materials. Due to the finely optical absorption in certain region of spectrum, these nanoparticles can be applied also for the therapeutic treatment of neoplastic diseases through a photo-thermal effect.

The free-standing nanofilms can be manipulated, folded and unfolded in water many times without suffering from cracks, disaggregation or from loss of conductive properties. After collecting them onto rigid or soft substrates, they retain their functionality.Possible applications are foreseen in the field of sensing and actuation, as well as in the biomedical field, e.g. as smart substrates for cell culturing and stimulation.
The invention is related to the obtainment of free-standing nanofilms of conductive polymers. The method to obtain these films comprises four steps. In the first one there is the sequential deposition of, respectively, a sacrificial material, a layer of an electrolyte, a layer of the conductive polymer and, eventually, a further layer of polyelectrolyte. The second step is a thermal treatment of the multilayer structure; in the third step the sacrificial support is removed and in the last step the free-standing multilayer structure is transferred in solution. Due to their characteristics of flexibility, robustness, adhesion to different substrates and biocompatibility, are particularly useful in biomedical applications, e.g. as support for cell grow.

The invention is related to the generation of magnetic fields, particularly for magnetic resonance imaging (MRI). MRI requires a high strength and uniformity magnetic field over a range of interest and in the case of human subjects it is also necessary that the shape of the magnet be suitable for easy positioning of the subject under examination; the volume occupied by the subject has to be located in a region of homogeneous field, i.e. in a region where the magnetic field exhibits equal intensity and is unidirectional. The invention is able to produce an open structure magnetic assembly characterized by producing a homogeneous magnetic field in an easily accessible region. The principle is to obtain homogeneous magnetic fields by adding magnetic fields originating by different structures.

The present invention relates to antimicrobial biocompatible nanocapsules constituted of cellulose acetate and lemongrass oil, which maintain its antimicrobial action, for biomedical applications. Said nanocapsules are suitable for safer drug delivering because of their high stability in water due to the lemongrass encapsulation in cellulose acetate nanoparticles by a hemiacetal bond between the aldehydes contained in the essential oil and the OH groups of the polymer. The method for obtaining the antimicrobial nanocapsules comprises a first step where cellulose acetate and lemongrass are dissolved in appropriate amounts of acetone and a second step where they are subsequently mixed with an appropriate amount of water; during this last step the in-situ nanoprecipitation of the product occurs and the size of the nanocapsules can be optimized tuning the acetone/water ratio. Finally the acetone is removed by evaporation in air under stirring and the obtained aqueous nanocapsules can be employed as prepared or as powder which is provided using spray dry technique.

The present invention provides a method to produce controllable sizes of protein nanoparticles (NPs), including gadolinium, in a sub-100 nm size range. The method uses a desolvation process by which bovin serum albumin (BSA) molecules self-assembly into NPs, during the addition of desolvation agents (i.e., ethanol or acetone).

After the desolvation and cross-linking processes, hybrid NPs containing both BSA and Gd3+ ions are formed in a controlled size range of 35-200 nm. The NPs are made to entrap magnetic resonance contrast agents (e.g., gadolinium chloride, GdCl3 or Gd-DTPA) and can be used as novel drug formulation for magnetic resonance imaging (MRI). Moreover, the formulation can be applied for enhancing the MRI signal of tumours in mammals.
