Aluminum Nanoholes: A Cost-Effective Material Platform for Optical Biosensors
Aluminum is much cheaper than gold, but its use as a plasmonic material in biosensors is limited due to its corrosion. This presentation introduces a method to overcome the issue with biosensor applications using aluminum nanoholes.

Conception and Development of Anti-Atherogenic Agents Inspired by Natural Fragments
Low-Density Lipoproteins Oxidized (LDLox) are atherogenic and cytotoxic when they contain large amounts of bioreactive carbonyl and advanced lipid peroxide products. We have developed a series of synthetic (poly)phenolic hydrazones based on vanillin and other related platforms. Their antioxidant, cytoprotective, and radical-scavenging properties in vivo will be presented, along with a proposed rationale.

Data Processing and Statistical Analysis in Experimental Measurements
Signal processing is a key step in converting raw data into useful information. Modern analytical systems produce data volumes that can no longer be processed manually. Moreover, obtaining samples and measuring them takes substantial effort, and it turns out that data matrices have more variables (columns) than measurements (rows). This problem, known as the "curse of dimensionality," leads to overloading mathematical models or pattern recognition systems. In this presentation, we will review preprocessing strategies to overcome the problem and discuss the best mathematical models to avoid overloading and achieve the best possible generalization. Additionally, we will demonstrate how statistical analysis is a key step in testing the generalization of results.

Impedance Model for Sensors with Nanocircuits
Immunosensors provide high sensitivity and selectivity when detecting specific components at low concentrations. One way to achieve this precision is by minimizing the sensor size. This reduces false effects like boundary diffusion or background noise, making it easier to integrate techniques such as impedance analysis in sensors.

Advances and Future Prospects of Functionalized Carbon Nanotubes for Molecular Recognition of Benzene
The weak interaction between carbon nanotubes and volatile organic compounds (VOCs) in general, and aromatic VOCs in particular, is well known. Functionalizing the walls of carbon nanotubes is crucial to improving sensitivity. We will review the use of cold plasma to introduce functional groups on nanotube walls and various methods for decorating them with metals or metal oxide nanoparticles to create gas-resistant sensors. We will also discuss our latest results on using receptors for aromatic compounds with weak interactions, such as CH-π and π-π, to trap aromatic agents (e.g., benzene), thereby achieving high sensitivity and selectivity.

Voltimetric Nanostructured Sensors for Antioxidant Detection
Antioxidants are compounds that prevent or slow down the oxidation of other molecules. Therefore, consuming antioxidant-rich foods (such as olive oil, fruits, and vegetables) is beneficial for health. Additionally, many antioxidants, such as polyphenols, influence the organoleptic characteristics of food and preserve it from oxidation caused by the environment.

Electronic Polymers for Biosensors
The field of biosensors has provided us with materials and instruments with a unique combination of properties, such as mixed ionic and electrical conductivity, mechanical flexibility, and biocompatibility, as well as the ability to refine material properties through chemical synthesis or mimicking active molecules. I will present examples of organic electrodes and transistors, which are gaining increasing attention as elements of a new generation of sensors and prosthetics.

Chemical Vapor Deposition by Aerosol of Functionalized Metal Oxide Nanowires for Chemical-Resistant Gas Sensors
The presentation will focus on the use of aerosol-assisted chemical vapor deposition (AACVD) to synthesize functionalized metal oxide nanowires. This method has recently been used to manufacture highly functional gas microsensors that are resistant to chemicals, based on tungsten oxide nanowires functionalized with second-phase particles (Au, Pt, Cu2O, and Fe2O3). It demonstrates that synthesizing, functionalizing, and integrating nanowires into micro-silicon or polymer devices can be achieved in a single processing step, which could be highly attractive for industry.
