1. Introduction Nano-bioformulations are innovative delivery systems that bring together the principles of nanotechnology with biological components to enhance the effectiveness of drugs, biomolecules, and agrochemicals. At the nanoscale (1–100 nm), molecules behave differently compared to their bulk forms, showing enhanced stability, solubility, bioavailability, and targeted delivery. These unique properties make nano-bioformulations a powerful tool in modern science, especially in medicine, agriculture, and biotechnology. The idea of working at the nanoscale was first envisioned by physicist Richard Feynman in 1959, who suggested that manipulating matter at the atomic level could open new scientific possibilities. 2. Types of Nano Bioformulations 2.1 Nanoparticles (NPs): Tiny solid particles (1–100 nm) made of polymers, lipids, or metals that are able to encapsulate drugs or biomolecules, protecting them from degradation and allowing slow, controlled release. Example: PLGA nanoparticles for anticancer drug delivery. 2.2 Nanoemulsions: Stable mixtures of oil and water at the nanoscale, stabilised by surfactants, can improve the solubility of hydrophobic compounds and are widely used in food, agriculture, and cosmetics. Example: Neem oil nanoemulsion for pest control. 2.3 Liposomes: Bilayered phospholipid spherical vesicles can mimic cell membranes and can carry both water-soluble (inside core) and fat-soluble (within bilayer) molecules. Example: Liposomal vitamin C for enhanced absorption. 2.4 Polymeric Nanocarriers: Biodegradable polymers such as chitosan or PLGA can form nanospheres or nanocapsules. They are...

कृषि में कार्बन नैनोट्यूब के साथ इन विट्रो दृष्टिकोण Nanotechnology, like tissue engineering, is built on assembling essential elements to create more complex structures. The process of creating structures and systems with new properties by using materials with at least one physical dimension between 1 and 100 nm is known as nanotechnology. Carbon nanotubes are vital in plant biotechnology because they affect the growth and differentiation of cells, tissues, organs, and entire plants. Carbon nanotubes can also be used to strengthen the structure of scaffolds and give them new properties, such as electrical conductivity, which may help direct cell growth. Carbon nanotubes may be a key biomaterial for making and keeping track of engineered tissue. They have various electronic, thermal, and structural properties that can be described by their diameter, length, chirality, or twist. Carbon nanotubes can be used in four ways that are important for tissue engineering: Tracking and labelling cells. Detecting how cells behave. Changing how cells behave. Improving tissue matrices. Carbon nanotube (CNT) is a versatile allotrope form of carbon with a cylindrical, long, tubular structure of rolled-up graphene sheets. CNTs can have a variety of structures based on their length, thickness, and number of layers. CNTs have become prominent due to their unparalleled mechanical, electrical, thermal, and chemical capabilities. Carbon nanotubes (CNTs) are nanostructured carbon...
