In the present study, cellulase has been immobilized by two different methods of entrapment viz. encapsulation in calcium alginate and matrix entrapment in agar. The calcium alginate encapsulated beads showed an immobilization efficiency of 92.

The banana fibers were modified using ultrasonication and cellulase enzyme, individually and in combination. Both native and modified banana fibers underwent physical, morphological, FTIR, and crystallinity analyses.

Starch is a natural, renewable, affordable, and easily available polymer used as gelling agents, thickeners, binders, and potential raw materials in various food products. Due to these techno-functional properties of starch, food and non-food industries are showing interest in developing starch-based food products such as films, hydrogels, starch nanoparticles, and many more. However, the application of native starch is limited due to its shortcomings.

There has been growing interest in the use of botanicals as alternatives to insecticides due to their widespread insecticidal properties, biodegradability, and adaptability to ecological conditions. In this study, we investigated the larvicidal activity and cytotoxicity effects of solvent extracts from three aromatic plants- (turmeric), (hoary basil), and (parsley)-against .

- - This study presents a new type of flexible electrode array designed for non-invasive monitoring of cervical nerve activity, using silver-silver chloride electrodes and a custom data acquisition system with real-time visualization.
- - Preliminary tests showed that this electrode design provides a high signal-to-noise ratio for capturing cervical neural recordings, and it has been named Cervical Electroneurography (CEN).
- - The research identified distinct firing patterns during stress tests on the autonomic nervous system, suggesting potential for future development of a portable CEN device for tracking autonomic regulation changes in both healthy individuals and patients with clinical conditions.
