“…Silica nanoparticles combined with composites are widely used for various applications (Soundharraj et al 2020) such as glucose biosensors when combined with gold nanoparticles to form mesoporous silica composite, by incorporating silica nanoparticles to carbon dots for bioimaging applications, in drug delivery when mesoporous mobil composition of matter (MCM)-41-silica is loaded with ibuprofen, monodispersed silica with uniform hollow-core mesoporous shell carbon nanospheres for supercapacitor applications. Different types of metal and metal oxide nanoparticles including silver, copper, palladium, zinc oxide, magnesium oxide, tin oxide are synthesized with various polymers and used for antimicrobial activity, food packaging, and improving shelflife of food (Rai et al 2018).…”

The rising use of radioactive elements is increasing radioactive pollution and calling for advanced materials to protect individuals. For instance, polymers are promising due to their mechanical, electrical, thermal, and multifunctional properties. Moreover, composites made of polymers and high atomic number fillers should allow to obtain material with low-weight, good flexibility, and good processability. Here we review the synthesis of polymer materials for radiation protection, with focus on the role of the nanofillers. We discuss the effectivness of polymeric materials for the absorption of fast neutrons. We also present the recycling of polymers into composites.

The development of fluorescent silica nanoparticles (SNP-RB) from natural amorphous silica and its performance as an Escherichia coli (E. coli) biosensor is described in this paper. SNP-RB was derived from silica recovered from geothermal installation precipitation and modified with the dye, Rhodamine B. The Fourier Infrared (FTIR) confirms the incorporation of Rhodamine B in the silica matrix. Transmission Electron Microscopy (TEM) micrographs show that the SNP-RB had an irregular structure with a particle diameter of about 20–30 nm. The maximum fluorescence spectrum of SNP-RB was recorded at 580 nm, which was further applied to observe the detection performance of the fluorescent nanoparticles towards E. coli. The sensing principle was based on the fluorescence-quenching mechanism of SNP-RB and this provided a wide linear E. coli concentration range of 10–105 CFU/mL with a limit detection of 8 CFU/mL. A rapid response time was observed after only 15 min of incubation of SNP-RB with E. coli. The selectivity of the biosensor was demonstrated and showed that the SNP-RB only gave quenching response only to live E. coli bacteria. The use of SNP-RB as a sensing platform reduced the response time significantly compared to conventional 3-day bacterial assays, as well having excellent analytical performance in terms of sensitivity and selectivity.

“…Silika (SiO2) merupakan salah satu material yang memiliki banyak aplikasi diantaranya sebagai bahan superhydrophobic, penguat beton, katalis, biosensor, bioimaging, drug delivery dan superkapasitor [1][2][3][4]. Secara alami silika memiliki tiga fasa utama yaitu kuarsa, tridimit, dan kristobalit.…”

“…Selama ini sebagian besar penelitian menggunakan TEOS (tetraethyl orthosilicate) sebagai prekursor untuk memperoleh silika. Namun beberapa diantaranya juga mensintesis silika dari biomassa seperti daun bambu, sekam padi, tongkol jagung, dan ampas tebu [4]. Selain biomassa beberapa penelitian juga menggunakan pasir yang memiliki kandungan silika yang kemudian dimurnikan untuk memperoleh silika kristal maupun amorf [1], [5][6][7].…”

Analisis komposisi unsur, senyawa oksida, dan fasa pasir pantai Citra, Kabupaten Sukamara berhasil dilakukan. Proses identifikasi komposisi unsur dan senyawa oksida menggunakan XRF, sedangkan identifikasi fasa menggunakan analisis XRD. Analisis XRF menunjukkan bahwa Si dan SiO2 mendominasi komposisi unsur dan senyawa oksida masing-masing sebesar 95,6% dan 98,1%. Selain itu, analisis kualitatif pola XRD menunjukkan bahwa SiO2 pada pasir pantai Citra adalah kuarsa. Hasil ini memberikan informasi bahwa pasir pantai Citra memiliki potensi yang sangat baik sebagai sumber SiO2.
