This paper focuses on the application of forensic science in latent fingerprint detection by the usage of distinct nanomaterials and their benefit with respect to the quality of fingerprint images. Nanotechnology is involved with the study of nanoscale materials, it is having a substantial impact in every industry. It is a widely used technique because of its ability to change and characterize matter down to individual and tiny atoms. Nanoparticles have recently showed considerable potential in the production of nano-fingerprints i.e. the nextgeneration of fingerprint development procedures. Silica nanoparticles were produced to detect invisible finger impressions on non-absorbent surfaces. Silicon usually has been obtained from mineral in rock and sand, however, silicon also can be obtained in organic material such as risk husk, bamboo leaf, wheat husk and another agricultural waste. Bamboo is a source of organic silica (bio-silica). The bamboo absorbs silicic acid from the water and then convert it into SiO2 hydrate in the root branches and leaves

Sodium alginate is a commonly used encapsulation matrix for variety of materials such as plant cells, food products, oil and flavor. This compound is biodegradable, biocompatible and non-toxic. Also, it is cheap, available, has chelating ability and forms stable reversible gels. However, plant extracts have challenges of poor utilization, poor stability, chemical degradation, low bioavailbility and high molecular weight. Therefore, this study was aimed at isolation, characterization and use of sodium alginate nanoparticles to encapsulate acetogenin compound isolated from Annona muricata leaf. Sodium alginate nanoparticles loaded with acetogenin compound were prepared and characterized using Transmission Electron Microscope (TEM) and Fourier Transform Infrared Spectroscope (FTIR). TEM revealed a spherical and irregular nature of sodium alginate nanoparticles loaded with acetogenin compound with particle size of 280nm. The encapsulation efficiency was 89% and this result shows that encapsulation in nanosized matrics with different concentrations of sodium alginate nanoparticles produced higher encapsulation efficiencies which therefore, enhances solubility, biovailability of acetogenin compound.
