Body fluid traces recovered at crime scenes are among the most important types of evidence
to forensic investigators. They contain valuable DNA evidence which can identify a suspect …

Raman spectroscopy was used to compare body fluids commonly found at crime scenes in
a nondestructive manner. The dry traces of semen, vaginal fluid, sweat, saliva, and blood …

Detection and identification of blood, semen and saliva stains, the most common body fluids
encountered at a crime scene, are very important aspects of forensic science today. This …

Knowing the time since deposition (TSD) of an evidentiary bloodstain is highly desired in
forensics, yet it can be extremely complicated to accurately determine in practice. Although …

Trace evidence materials are small quantities of chemical or physical evidence that are
found at a crime scene, on a suspect, or on a victim. According to the guidelines set by the …

We developed a carbohydrate sensing material, which consists of a crystalline colloidal
array (CCA) incorporated into a polyacrylamide hydrogel (PCCA) with pendent boronic acid …

We demonstrate a colorimetric glucose recognition material consisting of a crystalline
colloidal array embedded within a polyacrylamide−poly(ethylene glycol) (PEG) hydrogel, or a …

Many problems exist within the myriad of currently employed screening and diagnostic
methods. Further, an incredibly wide variety of procedures are used to identify an even greater …

Femtosecond time-resolved UV−visible absorption spectroscopy has been used to study the
UV photochemistry of trans-azobenzene (t-AB) in solution at 30 C. Photolysis of t-AB at 303 …

Amyloid fibrils are β-sheet rich protein aggregates that are strongly associated with various
neurodegenerative diseases. Raman spectroscopy has been broadly utilized to investigate …
