“…152 Thus, PHA particles can serve as drug vectors that can release drugs only inside the body since drug release from such drug-loaded PHA particles cannot occur without the PHA decomposition. 153 The slow release of anticancer drugs is a significant area of drug delivery. Human PhaP peptide and polypeptide or protein ligands fused to PhaP were advanced.…”

The diseases caused by microorganisms are innumerable existing on this planet. Nevertheless, increasing antimicrobial resistance has become an urgent global challenge. Thus, in recent decades, bactericidal materials have been considered promising candidates to combat bacterial pathogens. Recently, polyhydroxyalkanoates (PHAs) have been used as green and biodegradable materials in various promising alternative applications, especially in healthcare for antiviral or antiviral purposes. However, it lacks a systematic review of the recent application of this emerging material for antibacterial applications. Therefore, the ultimate goal of this review is to provide a critical review of the state of the art recent development of PHA biopolymers in terms of cutting-edge production technologies as well as promising application fields. In addition, special attention was given to collecting scientific information on antibacterial agents that can potentially be incorporated into PHA materials for biological and durable antimicrobial protection. Furthermore, the current research gaps are declared, and future research perspectives are proposed to better understand the properties of these biopolymers as well as their possible applications.

“…For instance, the molecular weight of PHA did not vary at 37 °C in a pH 7.4 phosphate buffer for over 84 days . Thus, PHA particles can serve as drug vectors that can release drugs only inside the body since drug release from such drug-loaded PHA particles cannot occur without the PHA decomposition …”

A novel electrochemical sensor based on Fe 2 O 3 nanoparticles supported on N-doped graphene (Fe 2 O 3 NPs/N-GR) has been fabricated for electrocatalytic oxidation and detection of L-cysteine. The Fe 2 O 3 NPs/N-GR was characterized by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy (XPS), and electrochemical methods. The electrochemical behavior of L-cysteine at Fe 2 O 3 NPs/N-GR was investigated by voltammetry. The Fe 2 O 3 NPs/N-GR showed a very efficient electrocatalytic activity for the oxidation of L-cysteine in 0.1 M phosphate buffer solution (PBS, pH 7.0). The oxidation peak currents increased dramatically at Fe 2 O 3 NPs/N-GR-modified electrode. The potential utility of the sensor was demonstrated by applying it to the analytical determination of L-cysteine. Experimental results showed that the electrocatalytic current increased linearly with L-cysteine concentration in the range of 0.2-400 μM with a lowest detectable concentration of 0.1 μM.

“…Besides that, for clinical use, they should be covered with some biocompatible material, which helps in its colloidal stability without harming its magnetic properties. For this, polymeric coatings, such as poly‐3‐hydroxybutyrate and polylactic acid, have been used. Other polymers, like poly (butylene succinate), can also be exploited for this application.…”

In this work, an extrinsically magnetic composite based on modified magnetite and poly (butylene succinate) (PBS) is prepared. The magnetic composite is obtained by the emulsion–solvent evaporation method. Several analytical tests confirm the synthesis of the composites. Among them, Nuclear magnetic resonance (NMR) results in comparison with literature confirms the synthesis of PBS. X‐Ray Diffraction (XRD) shows the characteristic peaks of PBS, in its monoclinic structure. The crystallite size (Lc) of magnetic particles inside the composite, is equal to 13 nm. Thermogravimetric analysis (TGA) reveals the presence of 5.3 wt% magnetite in the composite and demonstrates that the inclusion of magnetite does not affect the thermal stability of the polymer. The analysis of Fourier transform infrared attenuated total reflection spectra (FTIR‐ATR) indicates the synthesis of desired products as well as the encapsulation of magnetite in PBS polymer matrix. The composite presents magnetic force, which allows its magnetic guidance to a target area. Besides, the magnetic induction heating test promotes heating within the therapeutic range from 40 to 45 °C, being able, according to literature, to promote the death of several types of cancer's cells. Therefore, the material here presented possesses potential to be deeply researched as a future cancer treatment tool.
