Abstract: This review article is intended for the development of nanoparticles in cosmetics and the application of the nanoparticles in the cosmetic industry. The development of nanotechnology is going on at a steady pace for past few decades. The science of controlling molecules, atoms, particles in the nanoscale is called Nanotechnology, which is 80,00 times thinner than the diameter of a human’s hair. The world nanotechnology market size was valued USD 1.76 billion in 2020, and is forecasted to grow at a compound annual growth rate (CAGR) of 36.4 % from 2021 to 2030. Almost every cosmetic product is having nanoparticles as their constituents. The applications of nanotechnology in cosmetic products are called Nano-cosmetics. Nano-cosmeceuticals are utilized to fight against wrinkles, hyperpigmentation and dandruff. Nanotechnology offers various novel nanocarriers such as solid lipid nanoparticles, micro-emulsion, nano-vesicles, liposomes, fullerenes, nano-somes, nanostructured lipid carrier, nano-emulsions and nanospheres that act as transporters in order to eliminate the problems linkedto conventional dosage form. These nanocarriers prevent cosmetic agents from degradation, leakage, ultraviolet radiations and stability problems and hence increase the formulation efficacy, skin penetration and controlled delivery of active ingredients. On the contrary, the use of nanoparticles in cosmetic products can raise safety concerns and can cause environmental and health issues. Agencies like USA Food and Drug Administration, European commission ECHA, Nanotech in Brazil implemented laws for continuous testing and transparency based on researchesin order to ensure safety, effectiveness, quality of the cosmetic products containing nanoparticles. Food and Drug Administration(FDA) in the United States will be in charge of consumer products that include nanoparticles in cosmetics, food and pharmaceutical products.

Abstract: Tissue culture techniques have revolutionized the field of plant regeneration, with in vitro multiplication through shoot tip culture emerging as a pivotal method for generating pathogen-free planting materials. This technique is of paramount importance in mitigating field inoculum sources and rejuvenating disease-infested areas. This research explores recent developments in shoot tip culture techniques for Musa spp. cultivar Kabri, employing specific formulations of plant growth regulators, including cytokinins (BAP, Kin, 2ip) and auxins (NAA, IAA, IBA). This study investigates key aspects of banana micropropagation, with a focus on sterilization, in vitro shoot tip culture, and root formation and transfer in the field. Surface sterilization, crucial for eliminating contaminants, faces challenges, with ongoing research refining protocols to minimize risks. Evaluating survivability and contamination, the study found optimal results with 70% ethyl alcohol and 0.01% HgCl2 for 25 seconds and 10 minutes. In in vitro shoot tip culture, formulations involving BAP, Kin, 2iP, and Ads were explored. Among the hormones used, the combination of 3.0 mg/l BAP and 2.0 mg/l Ads demonstrated the best results with a 60% success rate for shoot initiation. This formulation resulted in an average of 2.65 ± 0.21 shoots per explant and a shoot length of 2.40 ± 0.42 cm. Root formation experiments revealed that 2.0 mg/l IAA induced an 81% root induction rate, with an average of 4.80 roots/explant and a length of 4.20 cm. Conversely, 2.0 mg/l IBA exhibited a superior 95% root induction rate, producing an average of 5.25 roots/explant with a length of 4.78 cm. Plantlets that had well-developed roots were effectively transferred to the field after undergoing comprehensive acclimatization procedures, achieving a 90% survival rate. These advancements carry significant implications for sustainable banana cultivation practices, providing researchers and practitioners with valuable tools for optimizing banana yields while ensuring pathogen-free crops.

Abstract: Human being get immune primer from birth during vaginal delivery; caesarean babies are debarred from this dose that is why they suffer more with infectious diseases during their early childhood period. In this paper we described methods of priming the c-section babies with mother’s microbiota for developing their immune system. It is now well established that mother’s faecal micobiota is the most appropriate immune primer for caesarean babies. We have also discussed here the mode of delivery of mother’s microbiota to the new born.
