Abstract
The main purpose of the experiment is to develop a greener low cost SNP fabrication steps using factories of secondary metabolites from Passiflora leaf extract. Here, the leaf extraction process is omitted, and instead a leaf disc was used for stable SNP fabricated by optimizing parameters such as a circular leaf disc of 2 cm (1, 2, 3, 4, 5) instead of leaf extract and grade of pH (7, 8, 9, 11). The SNP synthesis reaction is tried under room temperature, sun, UV and dark condition. The leaf disc preparation steps are also discussed in details. The SNP obtained using (1 mM: 100 ml AgNO3+ singular leaf disc: pH 9, 11) is applied against featured room temperature and sun condition. The UV spectroscopic analysis confirms that sun rays synthesized SNP yields stable nano particles. The FTIR analysis confirms a large number of functional groups such as alkanes, alkyne, amines, aliphatic amine, carboxylic acid; nitro-compound, alcohol, saturated aldehyde and phenols involved in reduction of silver salt to zero valent ions. The leaf disc mediated synthesis of silver nanoparticles, minimizes leaf extract preparation step and eligible for stable SNP synthesis. The methods sun and room temperature based nano particles synthesized within 10 min would be use certainly for antimicrobial activity.
Highlights

Summary
The nanoparticles formulation is beneficial for several fields that include electronic, textile, mobile phones, geo sensing technology, robotics, paper, space, food, construction, fertilizers, pesticides and agrochemical industries. The noble silver (Ag) is the metal of choice for synthesis of nano particles across the field of the biological system, living organisms and medicine. It is used for storing drinking water in ancient times. The silver nanoparticles are the vintage and preferred target of the green method related to against bacteria property of zero valent silver and easy reduction of silver salt to form zero valent silver (Singh et al 2014; Kharissova et al 2009) These Ag-NP (\100 nm) are used for wound healing, burns and other medical purposes. The silver nano particles possessed antibacterial property which makes it suitable for development into novel curative, pharmaceutical, textile, paint, food and agriculture industries
