Animal tissues are extensively used as scaffolds for tissue engineering and regenerative therapies. They are typically subjected to decellularization process to obtain a cell-free extracellular matrix (ECM) scaffolds. It is important to identify chemical structure of the ECM scaffolds and Fourier transform infrared (FTIR) appears to be a technique of choice. In this chapter, FTIR spectra of native and decellularized buffalo aortae, buffalo diaphragms, goat skin, and native bovine cortical bone are presented. The transmittance peaks are that of organic collagen amide A, amide B, amide I, amide II and amide III chemical functional groups in both native and decellularized aortae, diaphragms and skin. In bone, the transmittance peaks are that of inorganic ν1, ν3 PO43−, OH− in addition to organic collagen amide A, amide B, amide I, amide II and amide III chemical functional groups. These important transmittance peaks of the tissue samples will help researchers in defining the chemical structure of these animal tissues.

Palm Kernel Meal

Increased demand for wood adhesives, environmental concerns, and the uncertainty of continuing availability of petrochemicals have led to recent attention on protein-based adhesives. This study was conducted to investigate the physico-chemical interaction of palm kernel meal (PKM) with melamine urea formaldehyde (MUF) resins in adhesive formulation by using Fourier Transform Infrared (FTIR) Spectroscopy. The effect of hot press on PKM extender has been investigated by FTIR and blue shift is observed due to the hot press indicating that the functional groups (such as C=O, -OH and NH) are become more free in the samples. In the case of PKM-MUF blend bonding interactions observed where, PKM played the role as an extender. Red shift of C=O and N-H groups stretching in PKM-MUF-Wood blend is observed which suggests the interaction of these functional groups through hydrogen bonding. The results suggest that PKM extender-based MUF adhesive resins have potential application for the production of exterior plywood.

This work focused on a detailed assessment of lung tissue affected by metastasis of breast cancer. We used large-area chemical scanning implemented in Fourier transform infrared (FTIR) spectroscopic imaging supported with classical histological and morphological characterization. For the first time, we differentiated and defined biochemical changes due to metastasis observed in the lung parenchyma, atelectasis, fibrous, and muscle cells, as well as bronchi ciliate cells, in a qualitative and semi-quantitative manner based on spectral features. The results suggested that systematic extracellular matrix remodeling with the progress of the metastasis process evoked a decrease in the fraction of the total protein in atelectasis, fibrous, and muscle cells, as well as an increase of fibrillar proteins in the parenchyma. We also detected alterations in the secondary conformations of proteins in parenchyma and atelectasis and changes in the level of hydroxyproline residues and carbohydrate moieties in the parenchyma. The results indicate the usability of FTIR spectroscopy as a tool for the detection of extracellular matrix remodeling, thereby enabling the prediction of pre-metastatic niche formation.

The research aim was to study the effect of adding % weight alumina on the conductivity of polymer electrolyte chitosan-PVA-lithium. The characterization of functional groups was determined using fourier transform infrared spectrometry (FTIR). The Ionic conductivity of polymer electrolyte chitosan-PVA-lithium-alumina was measured by using impedance spectroscopy. The measurement results show the polymer electrolyte with the addition of 5% alumina provides the highest ionic conductivity of 3.991 x 10-3S/cm. Battery characteristics of electrolyte polymer of chitosan-PVA-lithium with the addition of alumina have a voltage of 1.4 Volts compared to commercial batteries which have a voltage of 1.5 Volts. These results indicate that alumina can be used as a filler to increase the ionic conductivity.

The purpose of the present research work is to investigate the functional group and category of secondary metabolites present in the essential oil (Eo) from Pogostemon benghalensis using Fourier transform infrared (FTIR) spectrometry, HPTLC and GC-MS technique. FTIR measures the vibrations of bonds within the functional groups and yields a spectrum that can be considered as biochemical or metabolic fingerprint of the plant product. Using FTIR spectra, it is possible to find out the minor changes of primary and secondary metabolic characteristic functional groups which are responsible for their biological feature of the species. FTIR is a nondestructive, cost effective, user and eco-friendly tool. Pogostemon benghalensis, a wild relative of P. cablin, the highly utilized and adulterated medicinal herb by the native people for the extraction of essential oil Patchouli. The fresh leaves were subjected to hydro distillation for the extraction of the essential oils and were analyzed using the above techniques. The FTIR spectral lines have shown diverse unique peaks of functional groups. FTIR confirmed the volatile compounds and indicated by their functional groups of the essential oils such as C-H (Alkene), C-H (aromatic) and C=C. Similarly, the analysis proved the presence of alcohols, p-substituted alcohols or phenols, alkanes, alkynes, alkenes, aldehyde, ester, ether, aliphatic amines, carboxylic acids, aromatics, ketones, disulphide, alkyl halides, halogen, and nitro derivatives. The intensity and estimation of predominant volatiles were analysed by   HPTLC, which showed 8 peaks with max Rf values ranged from 0.07 to 0.96. Further, the Eo was fractionated by with GC-MS technique and identified 41 volatile fractions in the oil.  Thus, the obtained data provides the biochemical profiles with overlapping signals of a wide array of molecules that are present in the cells. So, the usage of essential oils in pharmacy, cosmetology and aromatherapy industries may be substantiated. Further advanced spectroscopic analysis is required to identify the structure and nature of active principles present in the Eo.

 Parrot fish (Scarus sp) is a commodity which commonly consumed in North Sulawesi. High consumption of this fish has caused the high amount of fish scales as wastes. As parrot fish scales contain protein that could be transformed into commercial products such as collagen. Collagen could be applied in the industrial fields including cosmetics and pharmaceutics.  The purpose of this study was to determine molecular structure of collagen derived from the wet and dry parrot fish (Scarus sp) scales, based on molecular absorption of electromagnetic in the infrared region of the fourier transform infrared spectroscopy.Preparation of collagen of fish scales both in wet and dry forms, was initially performed with pre-treatment of raw materials by maceration in sodium hydroxide (NaOH) solution for 48 hours. Then hydrolysis process was conducted in hydrochloric acid (HCl) solution again for 48 hours to remove mineral contents of the scales.  Collagen yield of fish scales in wet and dry forms was 2.23% and 3.00%, respectively, with pH 7, and the respective  water content was  13% and 12%. For collagen derived from the wet scales, the functional groups of amide A and B absorb the electromagnetic at infrared region of 3429 cm-1 and 2930 cm-1), respectively. Also amide I, II and III absorb the electromagnetic at infrared region of 1657 cm-1, 1452 cm-1 and 1242 cm-1, respectively. It was comparable to that of collagen derived from the dry scales, the functional groups of amide A and B absorb the electromagnetic at infrared region of 3425 cm-1 and 2910 cm-1), respectively. Also amide I, II and III absorb the electromagnetic at infrared region of 1653 cm-1, 1402 cm-1 and 1244 cm-1, respectively.  The amide  III group of  the wet scales derived collagen as well as the dry scales derive collagen absorb the electromagnetics at infrared region in the range of 1309-1229 cm-1 indicating that the fish scale derived collagen has not denatured yet, but still in triple helix structure. Molecular functional groups detected for the parrot fish scales derived collagen are in the range of those for  collagen standard.Keywords : fish scale, Scarus sp, collagen, molecule structure, proximate  AbstrakIkan kakatua (Scarus sp) merupakan salah satu jenis komiditi ikan yang banyak dikonsumsi di Sulawesi Utara.
