Despite the outstanding progress in photonic sensor devices, a major limitation for its application as label-free biosensors for biomedical analysis lies in the surface biofunctionalization step, that is, the reliable immobilization of the biorecognition element onto the sensor surface. Here, we report the integration of bottom-up synthesized nanoporous graphene onto bimodal waveguide interferometric biosensors as an atomically precise biofunctionalization scaffold. This combination leverages the high sensitivity of bimodal waveguide interferometers and the large functional surface area of nanoporous graphene to create highly sensitive, selective, and robust biosensors for the direct immunoassay detection of C-reactive protein (CRP), an inflammatory biomarker widely used in the clinical diagnosis of infections and sepsis.

Objective: To identify under what circumstances a university student should be allowed academic accommodation for ADHD. To frame an evidence-based policy for use in Brazil based on a worldwide experience.
Methods: We reviewed the literature to acquire information on what documents are commonly required by disability services before accommodation for ADHD is made (including malingering detection).
In the modern world, animal and plant protein may not meet the sustainability criteria due to their high need for arable land and potable water consumption, among other practices. Considering the growing population and food shortage, finding alternative protein sources for human consumption is an urgent issue that needs to be solved, especially in developing countries. In this context, microbial bioconversion of valuable materials in nutritious microbial cells represent a sustainable alternative to the food chain.
