“…The application of MIR spectra has been increased by the use of the Fourier transform algorithm, several chemometric tools, and different available sampling methods such as transmission, transflection, and attenuated total reflectance (ATR) [ 33 ]. FTIR spectroscopy is a label-free and non-destructive technique [ 4 , 16 , 17 , 20 ].…”

Traditional renal biomarkers such as serum creatinine and albuminuria/proteinuria are rather insensitive since they change later in the course of the disease. In order to determine the extent and type of kidney injury, as well as to administer the proper therapy and enhance patient management, new techniques for the detection of deterioration of the kidney function are urgently needed. Infrared spectroscopy is a label-free and non-destructive technique having the potential to be a vital tool for quick and inexpensive routine clinical diagnosis of kidney disorders. The aim of this review is to provide an overview of near- and mid-infrared spectroscopy applications in patients with acute kidney injury and chronic kidney disease (e.g., diabetic nephropathy and glomerulonephritis).

“…189 Starch is the most abundant, renewable natural biopolymer and a very advantageous raw material that is inexpensively available for the synthesis of innumerable functional polymers. 190 Accordingly, starch is a biopolymer that is both effective as a surfactant agent and ecologically friendly, and its usage as a green capping and stabilizing agent in aqueous solutions has lately grown in importance in the synthesis processes of nanomaterials. 191 Starch was chosen because it is environmentally safe, biocompatible, and has hydroxyl groups in its template that prevent nanoparticles from aggregating.…”

The majority of pharmaceuticals are found in the environment as mixtures. However, a significant amount of these therapeutic compounds cannot be completely metabolized by the human body; thus, they are excreted through feces and urine and end up in wastewater treatment plants (WWTPs). The presence of pharmaceuticals and the degree to which they can be removed during wastewater treatment are now important research topics. Despite the adoption of various alternative technologies for the treatment of wastewater, the adsorption process is still regarded as a promising method due to its high efficiency, increased simplicity, and lower costs. Recent developments in the adsorption process involve the incorporation of an artificial molecularly imprinted polymer (MIP), which is a potent molecular receptor capable of selectively recognizing and removing pollutants. The MIP has advantageous characteristics, which include high affinity, predetermination, high stability, ease of preparation, and low cost. Notably, MIPs can be applied to the cleanup and preconcentration of analytes as the selective adsorbent of solid-phase extraction (SPE), magnetic solid phase extraction (MSPE), and dispersive solid-phase extraction (dSPE). Furthermore, MIPs can be produced as composite nanomaterials by employing nanoparticles (nanoMIP). The advancements of MIPs employed as sorbent materials for quantitative assessment and purification of pharmaceuticals in environmental water have been given most of the focus. Therefore, this study not only aims to present the fundamental ideas about the application of MIPs as sorbents but also gives an overview of the considerable initiatives made in recent years to enhance the performance of MIPs. Considering this, various current approaches to the development of MIP-based extraction techniques are detailed in the present review. This review also demonstrates how kinetics, thermodynamics, and isotherm models can be used to better understand the behavior of adsorbents and the adsorption process.

Polyhydroxyalkanoates (PHAs) as Biomaterials in Tissue Engineering: Production, Isolation, Characterization

Polyhydroxyalkanoates (PHAs) are biodegradable and biocompatible biopolymers. These biomaterials have grown in importance in the fields of tissue engineering and tissue reconstruction for structural applications where tissue morphology is critical, such as bone, cartilage, blood vessels, and skin, among others. Furthermore, they can be used to accelerate the regeneration in combination with drugs, as drug delivery systems, thus reducing microbial infections. When cells are cultured under stress conditions, a wide variety of microorganisms produce them as a store of intracellular energy in the form of homo- and copolymers of [R]—hydroxyalkanoic acids, depending on the carbon source used for microorganism growth. This paper gives an overview of PHAs, their biosynthetic pathways, producing microorganisms, cultivation bioprocess, isolation, purification and characterization to obtain biomaterials with medical applications such as tissue engineering.
