A label-free optical biosensor for rapid bacteria detection is introduced. The biosensor is based on a nanostructured porous Si, which is designed to directly capture the target bacteria cells onto its surface. We use monoclonal antibodies, immobilized onto the porous transducer, as the capture probes. Our studies demonstrate the applicability of these biosensors for the detection of low bacterial concentrations within minutes with no prior sample processing (such as cell lysis).

We developed a technology based on mesoporous silica thin film for the selective recovery of low molecular weight proteins and peptides from human serum. The physico-chemical properties of our mesoporous chips were finely tuned to provide substantial control in peptide enrichment and consequently profile the serum proteome for diagnostic purposes.

In some cases, like the 2005 Banda Ache earthquake in Indonesia, the damage involved large geographic areas and casualties in the six figures. In general, the number and intensity of earthquakes is not increasing, however, the vulnerability of the built environment is...
FAQs
Surfactant and block-copolymer templates direct precursor organization before the solid architecture is finalized. Their molecular assemblies arrange precursor species into an ordered pattern, so the resulting material reflects the template arrangement. Removing the template by extraction or calcination then makes the organized pore network accessible. This approach allows chemists to tune internal geometry rather than produce an unstructured solid.
Pore size, connectivity, surface chemistry, and composition provide the main design variables. Adjusting pore dimensions and connections changes the available internal environment, while surface chemistry and composition influence how the material interacts with molecules or chemical reactions. Controlling these features helps chemists tailor a structure for selective adsorption, heterogeneous catalysis, molecular separation, or controlled release.
After precursor organization has produced the intended solid architecture, the template is removed by either extraction or calcination. This step leaves the internal pore space available for chemical use, including adsorption, catalysis, separation, or release. Template removal is therefore an essential part of the synthesis workflow because the organized architecture cannot perform its intended function while the templating assembly occupies the pores.
A typical workflow begins by assembling a surfactant or block-copolymer template, followed by organizing precursor species around that molecular assembly. The solid architecture is then formed, and the template is removed through extraction or calcination. This sequence connects molecular organization with the final material’s pore arrangement, composition, and accessible internal environment.
Their tunable internal environments make these materials useful when researchers need controlled interactions between a solid and molecular species. Applications include selective adsorption, heterogeneous catalysis, molecular separation, and controlled release. Mesoporous structures also support chemical sensing, energy storage, and environmental remediation, where adjustable pore features and composition can be matched to the intended function.
Mesoporous silica, carbon, and metal oxides provide chemically distinct platforms for studying how confinement and internal surface environments influence material behavior. Their adjustable composition and pore characteristics also support functional-material design. In chemistry, these systems connect structural control at the nanometer scale with practical goals such as sensing, energy storage, catalysis, separation, and environmental remediation.
