Lithium‐Charged Gold Nanoparticles: A New Powerful Tool for Lithium Delivery and Modulation of Glycogen Synthase Kinase 3 Activity

open access: yesAdvanced Materials, EarlyView.
This study introduces glutathione‐stabilized gold nanoparticles for targeted lithium delivery (LiG‐AuNPs), enabling the controlled modulation of Glycogen Synthase Kinase‐3 (GSK‐3β). These non‐toxic, 2‐nm particles release lithium intracellularly, effectively inhibiting GSK‐3β in the brain without significant plasma lithium alterations.

Fiber Bragg Gratings with Micro‐Engineered Temperature Coefficients

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Fiber Bragg gratings (FBGs) are intrinsically responsive to temperature and strain simultaneously. In this research, low‐loss FBGs with micro‐engineered temperature coefficients are fabricated, utilizing refractive index liquid‐filled microchannels in the cladding.

A polynomial delay algorithm for the enumeration of bubbles with length constraints in directed graphs and its application to the detection of alternative splicing in RNA-seq data

open access: yes, 2013
We present a new algorithm for enumerating bubbles with length constraints in directed graphs. This problem arises in transcriptomics, where the question is to identify all alternative splicing events present in a sample of mRNAs sequenced by RNA-seq ...
