Harnessing biomaterials for advanced biosensor and bioelectronic devices development: From natural chromophores to biodegradable substrates and peptide-based detection of nanoplastics

Biomaterials play a crucial role in advancing biosensor technologies for medical, environmental, and food safety applications. This study investigates natural biomaterials, such as food-derived chromophores, cellulose, and peptides, for high-performance biosensors and bioelectronic devices. Chromophores, namely grape anthocyanins, are potential candidates for the development of artificial retinal devices showing light-responsivity at 435 nm, close to the human blue cone photoreceptors (420 nm...

A secure and quality of service-aware solution for the end-to-end protection of IoT applications

Internet of Things (IoT) applications increasingly rely on lightweight publish–subscribe protocols (e.g., MQTT) to exchange a considerable amount of sensitive data. However, such data are often threatened by external attackers, malicious insiders, and honest but curious Edge and Cloud providers. Typical security mechanisms — such as Transport Layer Security (TLS) or centralized data authorization management — may expose messages to intermediate nodes and fail to enforce Access Control (AC) po...

World Health Organization Evidence-Based Self-Help Plus Intervention for Stress Management via Chatbot: Protocol for Adaptation to a Tech-Enabled Model

Background: This paper describes the adaptation of an evidence-based intervention for mental health, Self-Help Plus (SH+), to a digital platform, aiming to expand mental health support through innovative technological solutions. The SH+ intervention, designed by the World Health Organization (WHO), is a low-intensity, self-guided program aimed at improving mental well-being. The intervention has been integrated into a chatbot-driven mobile app called "ALBA" (Automated Well-Being Assistant). O...

Habitat drivers and predicted distribution shifts of Anopheles coluzzii under climate change: Results from the systematic review

The two main Afrotropical malaria vectors - Anopheles coluzzii and An. gambiae, formerly known as M and S molecular forms - play a crucial role in malaria transmission in Sub-Saharan Africa. Despite their recent divergence, they exhibit distinct larval habitat preferences and micro-geographic distribution in West and Middle Africa. We performed a systematic literature review to retrieve studies that report counts of An. coluzzii and An. gambiae in their sympatric range since 2001, the year of...

Irradiation studies of the Resistive AC-coupled Silicon Detector (RSD/AC-LGAD)

Resistive AC-coupled Silicon Detectors (RSDs) are silicon sensors which provide high temporal and spatial resolution. The RSD is a candidate sensor to be used in future tracking detectors with the objective of obtaining ’4D’ tracking where timing information can be used along with spatial hits during track finding. 4D tracking will be an essential part of any future lepton or hadron collider and may even be feasible at the HL-LHC. For applications at hadron colliders, RSD sensors must be able...
